the onset of monsoons, for five years, in safe operation and maintenance of associated river training works of the Bangabandhu Bridge using state-of-the-art mathematical modelling and survey technologies. The working methodology of the project is as shown below.

Numerical Modelling in connection with River Bank Improvement Program (RBIP)The Joint Venture of Fichtner GmbH & Co KG (Germany) and Northwest Hydraulic Consultants Ltd (NHC, Canada) has been contracted by Bangladesh Water Development Board (BWDB) to carry out Consultancy Services for Technical Feasibility Studies and Detailed Engineering Design for River Bank Improvement Program (RBIP) for Assignment A.

Assignment A of the project includes, among others, technical and hydraulic modelling studies of the Jamuna River starting near Bangabandhu (Jamuna) Bridge and extending up to Kurigram upstream of the Teesta River (approximately 150 km), with detailed design studies focused on the 50 km reach between Bangabandhu (Jamuna) Bridge and Sariakandi. IWM was sub-contracted by the JV of NHC-Fichtner to provide consultancy services for numerical modelling of the Jamuna and its right bank floodplain.

Two-dimensional (2D) model was used to predict the possible impact induced by the proposed river training works, which had been planned to be constructed to restrain the right bank propagation towards the Brahmaputra Right Embankment (BRE), thus ensuring its safety. Such river training works (RTW) along the right bank of the Jamuna, proposed by NHC-Fichtner, were incorporated into the existing two-dimensional model of 2011 (available with IWM) to assess the impact on scour and erosion patterns of the Jamuna in the vicinity of the structures.

Six revetment-type structures of different lengths, stretching from Sariakandi to Shuvogacha, had been proposed by the JV Consultants, and these were included in the 2D model of the Jamuna in addition to the existing structures of the Jamuna for post-monsoon 2011 field condition. Incorporation of the structures was made on the available coarse grid model of 2011, thus making evaluation of impact difficult. However, it was found that, in general, the proposed structures do not cause major change in flow regime of the Jamuna.

Mathematical Morphological Modelling for the Kalni-Kushiyara River Management Project

Kalni-Kushiyara is one of the major river systems in the North-East region of Bangladesh. Over nearly four decades, it has been experiencing channel instability and sedimentation problems, which have led to

increased pre-monsoon flood damage, deterioration of navigability, and loss of productive lands and settlements. In this connection two-dimensional (2D) mathematical morphological model for the Kalni-Kushiyara river system has been developed using MIKE 21C river modelling software to investigate the sustainability of proposed river engineering options like dredging and loop cuts.

The Kalni-Kushiyara river system comprises number of branches, tributaries and floodplains. These features are also considered as transverse boundary in the 2D model. But discharge and water level vary significantly at the boundary locations due to significant flood plain flow. Thus, the model domain was subdivided into six reaches.

Under the framework of the study, Kalni-Kushiyara 2D model has been simulated, for the base condition as well as several options, to generate desired outputs. The outputs have been generated assessing the sustainability of the dredged channels and impact of options on the hydro-morphological behavior of the overall model domain. The hydro-morphological behavior and sustainability have been evaluated in

terms of bed level change, bank stability due to thalweg shifting tendency and flow obliquity; aggradations/degradation at different reaches; back fill volume of dredging; changes in flow distribution due to loop cuts, and erosion vulnerable reaches.

Chittagong WASA is embarking on construction of a water treatment plant at Modunaghat for production of 90 million litre per day treated water to meet its growing demand. During the dry season the salinity at the proposed Madhunaghat intake on Halda River sometimes (i.e., a number of weeks per year) crosses acceptable limit for drinking water. It may, therefore, be necessary to augment the water intake from Halda with lower salinity water for the proposed water treatment plant during high salinity periods to maintain the salinity within the prescribed limits. In

this background CWASA engaged IWM (1) to investigate potential rainwater harvesting options to augment the water supply to Chittagong city and (2) to investigate the groundwater aquifer system near the proposed Modunaghat water treatment plant, with the aim of using groundwater to augment the water intake of Modunaghat WTP to lower the salinity level of raw water from Halda River during high salinity periods to maintain the salinity within the prescribed limits.

Irrigation Management (IRM) division has achieved a leading position in the field of integrated management of land and water resources through mathematical modeling studies and detailed hydrological and hydrogeological investigations for Bangladesh and abroad. IRM plays an important role in agricultural productivity through improved irrigation by adopting (sustainable) water resources management. Using mathematical modeling, IRM supports water managers at home and abroad in structuring complex decision-making processes and provide technical know-how for effective evaluation of planning alternatives. Information management systems, decision support systems and simulation models are important tools in this respect. IRM provides technical support in different stages of project cycle i.e pre-feasibility stage, feasibility & planning stage. Implementation stage, operation and maintenance stages are also monitored by using diversified tools such as MIKE SHE, MIKE-11,MIKEGIS, MODFLOW, FEFLOW, HYMOS, CROPWAT etc., supported by ICT and sophisticated data collection systems.

During the year 2014, IRM division completed several critical projects of national and international interests. Successful completion of studies includes Hydro-geological Study and Groundwater Modelling for "Northern Part of Barapukuria Coal Basin Area, Availability of Groundwater Resources in the State of Selangor, Malaysia, Groundwater Resources Study and IIS Development for 8 Districts of Rajshahi Division, BMDA Phase-II", Salt Water Intrusion in Groundwater in the Coastal Area, etc.

Hydrogeological Study and Groundwater Modelling for Northern Part of Barapukuria Coal Basin Area

Barapukuria Mine is the only underground coal mine in Bangladesh. This mine is underlain by thick (Avg. 107 m) water bearing strata (Aquifer) and located in Dinajpur district of North-West Bangladesh. The depth of coal is between 118 m to 509 m with 6 Nos.

of coal layers. The average thickness of coal seams is near about 36 m with a reserve of 390 MMT. The present underground mining area covers 3 Km2 in central point out of a total 6.68 Km2 reserve area. No coal extraction is carried out from the Northern 2.81 Km2 (Reserve 135 MMT Approx.) area.

The study is conducted to develop a preliminary mine plan, dewatering requirements, impacts of dewatering of groundwater, water quality analysis, preliminary mine water management plan for the proposed open pit in the Northern Part of Barapukuria Coal mine area. The major activities that has been performed under this study includes hydrogeological investigations, preliminary mine plan and development of mathematical modelling.

Hydrogeological investigations illustrates that in the northern part, coal Seam VI is directly connected to Upper DupiTila aquifer formation comparatively at shallower depths and there is no existence of coal beyond the outcrop as defined by Wardell Armstrong. The coal seam water quality is alkaline in nature due to low sulpher content (0.53%) of coal composition.

The preliminary mine plan was conceived for 25 years considering 5 phases and each phase duration is 5 years (Figure-I). The proposed mine plan covers an area of about 2.03 Km2 for an extractable coal amounting to 116 million tons. Model output reveals that about 6216 Mm3 of groundwater is required to be dewatered for the proposed open pit mining for a period of 25 years. Based on the Depth to Groundwater Table (DGT) 4 nos. of influence zone has been demarcated as shown in Figure-2. For Zone-1 (DGT<7m) agricultural demand will be fulfilled by existing irrigation facilities. In that case, for Zone- 2 (DGT within 7m to 22m) existing STW needs to be replaced by DTW. Where as in Zone-3 (DGT within 22m to 30m) all the tubewells has to be rehabilitated by deep set DTW. In case of Zone-4 (DGT>30m), the dewatering water will be delivered to farmers and other domestic users by large diameter pipelines and trenches/canals from the mine dewatering system.

A number of minor canals and ponds exists surrounding the proposed mining area which may be used to drain out and storage used for the dewatering water. This water can be used as irrigation water and it also

reduces the impacts of dewatering. A flow barrier option along the periphery of mine up to the bottom of UDT has also been investigated which reveals that the impact zone will be confined within the proposed barrier and only 800 Mm3 of water will be required to be dewatered for a duration of 25 years.

A detail study is recommended to implement this option. To identify the impacts of reinjection on dewatering and zone of influence, an option has been tested considering 42 nos. of reinjection well with a capacity of 1 cusec. The option reveals that about 13% of impact will be reduced due to dewatering in comparison with no reinjection. The post-mining model runs show that groundwater level will recover to the base condition within about 6-7 years of cessation of mining. This study covers only the technical part of preliminary mine design and requires further detailed feasibility including environmental viability, economic feasibility and social acceptability before implementation of the proposed project.

Assessment of Impacts of Anticipated External Drivers of Change on Water Resources in the Coastal ZoneThe study was undertaken to identify key drivers of changes in surface water resources in the Ganges delta, The objective included to prioritise likely future scenarios and to assess the likely impacts of these scenarios on salinity intrusion and fresh surface water availability. Drainage congestion along with storm surge inundations and out-scaling research results for changing knowledge. Attitude and skill of planners, implementing agencies other stakeholders were also included in the study.

The process for identification and prioritization of external drivers of change for scenario analysis involves a wide range of stakeholders. It includes farmers, fishermen, researchers, academics, and representatives of planning and implementing agencies working in Bangladesh. The list and rank of identified drivers of changes are; Change in transboudary flow,population growth, change in water mangament practices, land use change, climate change etc.

The change in trans-boundary flow in last forty years has shaped the water availability in the coastal Ganges tidal plains. The annual minimum flow in the Ganges decreased from 1920m3/s in 1974 to 730m3/s in 2013. The salinity monitoring results shows that salinity was as high as 9.3 ppt in 2013 whereas it was less than 0.5ppt before 1975. Reduction in trans-boundary flow reduces the area extent of river water usages in irrigation (0-2ppt salinity) especially in the Gorai dependent area. At present, there is enormous amount of freshwater suitable for irrigation practices for agricultural crops throughout the year in Barisal Division.

The quantity of freshwater in the coastal zone is likely to decrease due to the combined effects of external drivers and inadequate trans-boundary flows which will increase river salinity during the dry seasons. By 2030, the area suitable for irrigation (less than 2 ppt river water salinity) is likely to be decreased by about 11% under a moderate climate change scenario (A1B). However, under this scenario, in 2030, salinity of rivers in Barguna, Patuakhali and Jhalokathi districts will not exceed 2 ppt, meaning continued high availability of river water for irrigation in these regions, even with 22 cm sea level rise.

However, the fresh water pocket in the south central zone is likely to become more saline (2-4 ppt) with climate change and 52 cm sea level rise in 2050, damaging fish habitat and sources of irrigation water. If the proposed Ganges barrage is built in the Ganges river to divert flow through the Gorai river, an additional 2660 km2 area would be exposed to river water salinity of less than 2 ppt compared to the base condition i.e. a larger land area would have access to irrigation. With sea level rise of 22 cm, the Ganges barrage would still result in an additional area of 886 km2 with river water suitable for irrigation.

In moderate saline area (Polder-30), storage of freshwater in improved internal drainage canals can meet irrigation demand of Boro rice for 20% area of fallow land. In high saline areas, brackish water can be considered as a resource that, if properly managed, can be used for high-income aquaculture without affecting production of Aman rice. Existing informal structures can be replaced by a smaller number of formal structures and improved canal system for both drainage and flushing. Present drainage system needs to be revisited to meet the demand of flushing brackish water. The study analyzes the potentials of drainage improvement by sub-polderization/sub-hydrological units considering land level, canal system, tidal characteristics of peripheral rivers and road network. Sub-poldering can provide better drainage management reducing high/low land conflicts and improvement and easy maintenance over the years.

The division has been providing technical backstopping support to Flood Forecasting and Warning Centre (FFWC) of BWDB in its routine flood forecasts in the past decades. The division developed and continuously updating the Ganges Brahmaputra Meghna (GBM) basins model which is capable of increasing the lead time of flood forecasts as well as a tool to assess climate change impacts and making water resources assessments on a regional context.

World wide accepted modelling tools such as MIKE 11, MIKE GIS, MIKE FLOOD, MIKE BASIN, FLOOD WATCH, MIKE CLIMATE CHANGE are being used in the division to address a wide range of water management issues. Other modeling tools such as SWAT and WRF are also being used for developing and assisting hydrological activities carried out by the division.

Important projects carried out by FMG in 2014 includes, Implementation Support Services for 'Kalni-Kushiyara River Management Project', 'Bangla-Dutch Research Initiative on Flood Risk Management', 'Water availability, demand and adaptation option assessment of the Brahmaputra River Basin under climate change' in joint collaboration with ICIMOD-HICAP, 'Index based flood insurance', 'Satellite based Flood Forecasting System at FFWC', 'Development of Water Management Model for Selangor and Langhat River basins' of Malaysia etc. In addition, the division contributed to train IWM professionals and clients in the field of weather research and forecast model, disaster risk reduction and advanced mathematical modeling technology for flood management applications at home and abroad.

Satellite based Flood Forecasting System at FFWC The main objective of this study is to implement Satellite Altimetry Based Technology (SABT) in the presently operational Flood Forecasting and Warning System in Bangladesh. It is expected that through introduction of SABT, dependency on hydro-meteorological information from the transboundary regions would be reduced and this would also help contribute in increasing the lead time (up to 8 days) of present flood forecast.

The 8 day forecast for Bahadurabad and Hardinge bridge is based on the trend of forecast derived from a period spanning 2008-2013 (6-years) in which JASON-2 flew over the Ganges-Brahmaputra basins. The JASON-2 data pertains to the GDR (Geophysical Data Record) and not the IGDR (Interim Geophysical Data Record). While producing forecast using this data, some human judgment is also applied.

Bangla-Dutch Research Initiative on Flood Risk Management

With a view to enhancing the cooperation between UNESCO-IHE and Bangladeshi knowledge institutes in the water sector a research project titled 'Bangla-Dutch research initiative on flood risk management and morphological assessment' has been initiated under DGIS UNESCO-IHE Programmatic Cooperation. The Dutch-Bangla joint research initiative shortly titled as "MorphoFlood" carried out by UNESCO-IHE (The Netherlands), and BUET (Bangladesh), CEGIS (Bangladesh) and IWM (Bangladesh). The overall study

has been planned to cover two broad thematic areas: flood risk management and morphological assessment. In this joint research initiative, Bangladesh has been chosen as the research case, and partnerships between the academicians (UNESCO-IHE and BUET) and applied researchers (IWM and CEGIS) helped in blending the theoretical and practical research experiences to achieve an implementable and sustainable research outcome.

The research component 'Flood Risk Assessment of Haor Area' conducted by FMG division focuses on the flooding issues in the Haor region in the North-east of Bangladesh. Limited studies on the region, particularly

with the help of numerical models, have been carried out in the past. Therefore, an objective of the current research was to set up numerical models capable of reasonably emulating the physical system. Such models could, for example, associate different gauges to the spatio-temporal variation of hydrodynamic variables and help in carrying out a systemic study on the impact of climate changes.

A 1-2D model, with 1D model for the rivers and a 2D model for the haors were developed. In order to keep

the computing load within feasible limits the most-flood prone area of the region, often loosely defined as the deeply flooded area, consisting of about 15 haors were chosen as the model domain. Based on the simulation results corresponding to the 2004 pre-monsoon and monsoon floods, the flood propagation within the model domain was studied and characteristics of rivers (and areas) with fast and slow responses to flood waves were identified. Initial studies on climate change indicate substantial impact on the region. Future studies will evolve around making use of remotely sensed data in improving the understanding of the hydro-meteorological characterization of the area.

Local Level Flood Forecasting Applying Remote Sensing Technology in River Basin Management of Bangladesh

Flood Forecasting and Warning Centre (FFWC) of BWDB provides flood forecast with lead time of five days at 54 gauge stations located in the major rivers of the country. The procedure of boundary estimation is critical and accuracy of it is quite dependent on the personal skill of the engaged professional. Real time hydrological and meteorological data of cross border catchments is insufficient in quantity and are very much essential for generating quality flood forecast in the country. In the same time, it is also envisaged that making the availability of real time data from cross border catchments is a great challenge. However,

different types of satellite estimated information are being popular in the world these days. This study has been carried by Institute of Water Modelling (IWM) for application of near real time satellite estimated precipitation in order to strengthen the existing flood forecasting system and capacity development of FFWC for effective flood management in the country. The specific objectives of the study is to improve existing flood risk management systems in BWDB in two target areas with the earth observation satellite data; applying satellite-based geographical models to the local flood models and evaluating its effectiveness and training & capacity building of FFWC professionals. Two target areas: Kulkandi Union of Jamalpur district (Pilot area 1) and Jadurchar Union Kurigram district (Pilot Area-2) were selected for

developing local level flood forecasting system under this study. A local flood forecasting system for the target areas has been developed under the study. The system needs real time GSMap made available by JAXA, real time water level and rainfall available at FFWC, BWDB and rainfall prediction made available from various web based sources or produced through simulation of WRF model. The system is developed using the software: MIKE ZERO of DHI, Denmark. In addition, an Interface has also been developed for management of data, generation of flood forecasts, and processing of forecast outputs for greater circulation.

The local flood forecasting model generates flood forecasts with lead time of five days in the target

areas. The outputs of the local flood model includes flood forecast hydrographs, bulletins along with flood inundation maps of Kulkandi and Jadurchar Unions of the target areas. The model is facilitated to generate flood forecast at important locations like office complexes, institutions, structures, or any other desired locations in the two target areas. The GSMap is itself under calibration, and it is expected that better performance of flood forecast may be achieved if calibrated GSMap data is used. Besides, apply correction in rainfall prediction produced by WRF model or calibration of WRF model or both together may produce a better flood forecast for the target areas.

Research & Development

Research Project: A Study on the Effect of Oblique Flow and Char Movement in River Bank and Bank Protection Work

Bangladesh is an alluvial delta of the Ganges, the Brahmaputra and the Meghna rivers. Rivers are very active in nature in this country. The enormous amount of discharge and heavy sediment load cause the rivers

to be unstable, and the channels are constantly migrating laterally. As a result there are active bank erosions all over the country at different reaches of the rivers. The rivers are generally meandering and/or braided in nature. For meandering rivers, normally erosion occurs in concave bank. But, there is no systematic pattern of erosion in the braided river system. Erosion pattern in a braided river have a unique nature due to the presence of numerous bars and islands (chars) within the channel that create oblique flow in the channels.

There are a number of variables in a braided river, and it is very important to understand its complex behaviour to prevent erosion in the vulnerable banks, especially which are under threat of oblique flow. Different studies on braided river are mostly qualitative. But there is a significant lack of quantitative studies on the effect of oblique flow for braided rivers. This study has been carried out to understand the process of oblique flow in a braided river.

Physical modelling along with mathematical modelling is a better way to perceive the nature of rivers due to flow current interactions. The research has been conducted by physical and mathematical modelling to understand the behaviour of a part of a braided river when it is under the threat of oblique flow.

The physical model for this research was developed in River Research Institute (RRI), Faridpur. The physical model was developed in a scale ratio of 1:50 for a straight bank with variable oblique channel angles and different discharge ratios. Each setup was developed to understand the effect of oblique flow on main channel.

Mathematical modelling was carried out using different data such as initial and final bed level of cross-sections, velocity, water surface slope, flow line, scour pattern and flow on bank line as obtained from physical model runs. As physical model is a scaled model, before using the input data in mathematical model, all the data, except grain size, were converted. In both physical and mathematical models, effect of oblique angle 20°, 40° and 60° with different discharge ratios 1:1.2, 1:1.4 and 1:1.6 were investigated. Mathematical model have been calibrated with respect to physical model.

Effect on unprotected bank, bank protection works and launching behaviour of different protection material due to oblique flow has been assessed. Stone boulder and geo-bags have been used as river bank protection material. Bank shifting tendency and bed scour in unprotected bank have been observed and measured. Some factors for design of bank protection work have been reassessed according to the results obtained from the models. Relation of oblique flow angle and discharge ratio with respect to main channel on scour has also been established.

Two Master of Engineering (M. Engg.) degrees, based on this research work, have been awarded by the Department of Water Resources Engineering (DWRE),

BUET, and another student is still working for Master of Science (M.Sc.) program. It is noteworthy that the current research work is the joint contribution of different institutions/organizations (BUET, IWM, RRI and BWDB) with a view to carry out a purely scientific research work. IWM arranged for the requisite funds for the whole research work.

Though minor but it is expected that the research work, carried out with the help of physical and mathematical model, would add to knowledge bank and guide other researchers intending to explore this field of research. This may be termed as the beginning of research on oblique flow. As oblique flow changes and accelerates the erosion process in a braided river than that in a meandering river, so, further research is required to generate conclusive results for determination of definite parameters, which can be used in designing bank protection work considering the effect of oblique flow on the main channel.

Some photographs of the workshop on this research project are as follows. The workshop was presided over by the Executive Director of IWM, Professor Dr. M. Monowar Hossain, and the Chief Guest was the Secretary of the Ministry of Water Resources, Government of Bangladesh.
