Global Perspective
Climate-induced increases in sea level are caused by thermal expansion of the oceans and melting of land ice and ice sheets
Average Rate ~ 1.8 mm/year
0.8 mm/year
2.0 mm/year

2. Mean Sea Level is projected to rise by 0.18 m to 0.59 m by 2100, But with Significant Regional Variations, IPCC 2007)

CoRI Activities
Impact of climate changes on coastal zones was investigated by MWRI, Coastal Research Institute )CoRI( and Delft Hydraulics, Netherlands )1989-1992(
The study at that time has estimated the sea level rise impact on all the entire coastal zones of Egypt )3500 km( in terms of quality and quantity.
The study focused on the Nile Delta coast as it has been considered the most vulnerable area in the coastal zones of Egypt
The study estimated the impacts of sea level rise if water has raisin by 1m, 2m, and 3m as shown in the figure.
Egyptian Coastline15 Coastal Segments for Vulnerability Assessment Study
Results of the study show the vulnerable areas to sea level rise in the Nile Delta with different water levels
1m zone
2m zone
3m zone
Areas of Ecological interest in the Red Sea area
Vulnerability Analysis
Physical Mechanisms Shoreline erosion/accretion Flood frequency Directly exposed hydraulic structures : e.g. ports, commercial
facilities, fish farms Salinity intrusion
Major Impact and possible losses Water level, waves characteristics, sediment flow, salinity levels Ecological sustainability Socio-economic responses, recreational capacity, tourism Agricultural activities and drainage conditions Fresh groundwater availability
Conclusion & Recommendations (1992)
ConclusionsIf no response strategies are planned, major adverse impacts and serious
losses are expected in terms of: Deficiency in infrastructure functionality Community displacement Ecological deterioration Penetration of salt wedge Deficiency in drainage capacity
Recommendations A comprehensive national response strategyCoordinative actions to minimize risks and maintain ecosystemPreparation of integrated coastal zone management schemeRegular monitoring of vulnerable regionsFurther studies & follow up of technological developments
Vulnerable areas defined by CoRI and Delft in 1992.
Vulnerable areas defined by IPCC in 2007
Results by CoRI & Delft )1992( and IPCC )2006( are comparable
Because both studies ignored the morphological features of the
coastal zone of the Nile Delta as )coastal sand dunes and ridges( .

Two Modules have been developed and in each module three scenarios were established
•The first scenario was established by assuming that the same rate of temperature change )0.6 ºC over the last century( will occur till 2100.
•The second scenario was established by temperature projection till 2100. Temperature change is assumed to be 1.8 ºC above 1990 limit till the end of the current century.
•The third scenario was established by temperature projection to be 4.0 ºC above 1990 limit till the end of the current century.
Mediterranean Hydrological Factors
Area = 2.5 million km2
Max Depth = 4400 m
Ave Depth = 1500 m
Water Vol. = 3.7 million km3
Water body comprises 3 layers with different temperature and salinity profiles
• Surface layer )75-300 m depth(
• Intermediate layer )300-600 m depth(
• Lower layer )more than 600 m depth(
Mediterranean Annual Water Balance
Evaporation 4144 km3
Income
rainfall 1000 km3
River flow 230 km3
Black Sea flow 152 km3
Total Inflow 1382 km3
Deficit 2762 km3
This deficit is compensated by 40,000 m3/s from Atlantic Ocean through Gabal Tarek straight in an anti-clockwise flow as water level in eastern side of the sea is 80 cm lower than that in the ocean due to increased evaporation rates difference.

Adaptive Supporting Systems
According to IPCC summary report for decision makers, Nov. 2007, it is recommended to create wetlands in areas vulnerable to the impacts of sea level rise in low lying deltas. )Al-Manzalla, Al-Burullus, Idku, and Maryot Lakes are one of the natural adaptation processes(.
Protection constructions carried out by Shore Protection Authority )SPA( )Damietta, Rosetta, and Al-Burullus(.

•Resources and capacities of Coastal Research Institute )CoRI( built since 1971 and other related-research institutions in Egypt.
•The international road could act as the second defensive line to protect north zone of the country. In this concern, it should be mentioned that UNDP in 1992 had a roundtable meeting about considering the road as a mitigation measure against the impact of sea level rise.
•Al-Salam Canal goes by Al-Manzalla Lake and its banks have levels more that two meters above lake's water level. Aerial-photos used in the study do not consider the canal as they were established before its construction.

Adaptation Process and Policies
Sand dunes systems should be treated as the first defensive line for the Nile Delta.
Decision makers in coastal governorates as well as concerned ministers should be aware of the importance of sand dunes systems and their role in protecting the coastal zone of the Nile Delta.
Consideration should be paid to coastal lakes as one of the most appropriate adaptive measure against sea level rise.
Coastal international road should be considered as the second protection measure and studies to support it are urgently required.
Coastal protection constructions need regular maintenance and should be considered in any coastal zone management plans.
The northwest coast extended from Alexandria to the Egyptian-Libyan borders is not vulnerable as it has elevation more than 10 m above average sea water level.
Recommendations Capacity building in terms of staff, technologies, modeling, ….etc. A comprehensive national and regional response strategy Coordinative actions to minimize risks and maintain ecosystem Preparation of integrated coastal zone management scheme Research budget and funds should be increased to cope with the
national and international crisis regarding climate change and its impacts and adaptation studies.
Building co-operative mechanizm to integrate all efforts Awareness program and media campaign Regional monitoring and observation system Regional data base and knowledge exchange system Regular Maintenance program for protection structures The following aspects are recommended to be covered in further
studies for the coastal zones: Potential impacts on land and groundwater salinity Potential impacts on patterns of waves and currents
Potential impacts on erosion and accretion systems due to currents, waves, and wind actions
Potential impacts on lakes ecosystems Potential impacts on water resources and drainage
systems Potential impacts on fisheries due to changes
expected in current patterns Potential impacts on infrastructures and natural
resources of the coastal zone of the Nile Delta Potential impacts of climate changes on evaporation
from oceans and seas open waters and their role in reducing SLR
Potential impacts of temperature increase on phyto-plankton role in absorbing CO2 and generating A2.
