INTEGRATED APPROACHES ARE USING WATERSHED MANAGEMENT SYSTEM WITH REMOTE SENSING AND GIS

05032023

Watershed Definition ldquoWatershed can be defined as a unit of

area covers all the land which contributes runoff to a common point or outlet and surrounded by a ridge linerdquo

Deterioration of watershed takes place due to faulty and bad management through the activity of man and his animals

05032023

WATERSHED-is a natural hydrological unit

-Topographically delineated area drained by a stream system from which runoff resulting from precipitation flow past from a point into single stream

-Development is not confined just to agriculture lands but covers entire catchments area

- Watershed approach is holistic linking upstream anddownstream areas

-Practical approach in planning directed at preservationconservation development management and exploitation ofnatural resources for the benefit of people

WATERSHED-is a natural hydrological unit

-Topographically delineated area drained by a stream system from which runoff resulting from precipitation flow past from a point into single stream

-Development is not confined just to agriculture lands but covers entire catchments area

- Watershed approach is holistic linking upstream anddownstream areas

-Practical approach in planning directed at preservationconservation development management and exploitation ofnatural resources for the benefit of people

B Feasibilities Alternatives amp recommendations Some of the techniques can be used in watershed management as given below

1 Broad beds and furrows2 Artificial recharge3 Check dames 4 Terracing5 Grassland development6 Tree plantation 7 Lift irrigation schemes8 Stopping ground water flow9 Storage of rain water 10 Connecting to other water body etc

1 Broad beds and furrows

bull Function To control erosion and to conserve soil moisture in the soil during rainy days

2 Artificial recharge Function To increase ground water level so that it can be used in scared condition To augment the ground water recharge

Percolation canal

05032023

Percolation pond

4 Check dams

Function To conserve water by constructing check dams and use it when required

5 Bench Terracingbull Function It helps to bring sloping land into different level strips to enable cultivation

05032023

Remote sensing makes it possible to collect data of dangerous or inaccessible areas

Remote sensing also replaces costly and slow data collection on the ground ensuring in the process that areas or objects are not disturbed

A technique of obtaining information about objects through the analysis of data collected by special instruments that are not in physical contact with the objects of investigation

Remote sensing

Remote sensing platforms

Ground-based Airplane-based Satellite-based

05032023

ROLE OF REMOTE SENSINGUseful for generating environmental indicators that can beintegrated with collateral data and social indicators- Synoptic view Multi-resolution multi-spectral repetitiveoffers appropriate method for quick unbiased mapping andmonitoring of natural resources both in space and timedomain- Timely and accurate information on spatial distribution ndashland use soil vegetation density forest geology waterresources etc- RS data in conjunction with collateral data helps indelineation of ridge line characterization prioritizationerosion prone areas etc

GIS Basics Geographic Information System

Allows the viewing and analysis of multiple layers of spatially related information associated with a geographic regionlocation

Remote sensing makes it possible to collect data of dangerous or inaccessible areas

Remote sensing also replaces costly and slow data collection on the ground ensuring in the process that areas or objects are not disturbed

A technique of obtaining information about objects through the analysis of data collected by special instruments that are not in physical contact with the objects of investigation

Remote sensing

Remote sensing platforms

Ground-based Airplane-based Satellite-based

05032023

ROLE OF REMOTE SENSINGUseful for generating environmental indicators that can beintegrated with collateral data and social indicators- Synoptic view Multi-resolution multi-spectral repetitiveoffers appropriate method for quick unbiased mapping andmonitoring of natural resources both in space and timedomain- Timely and accurate information on spatial distribution ndashland use soil vegetation density forest geology waterresources etc- RS data in conjunction with collateral data helps indelineation of ridge line characterization prioritizationerosion prone areas etc

GIS Basics Geographic Information System

GIS Basics Geographic Information System

Allows the viewing and analysis of multiple layers of spatially related information associated with a geographic regionlocation

Both spatial and attribute (tabular) data are integrated

The widespread collection and integration of imagery into GIS has been made possible through remote sensing

Ground Water Water present in the subsurface environment of earth is called

Groundwater an important component of water resource systems

Groundwater is the largest reservoir of fresh water that is readily available to humans( 90 of Earthrsquos fresh water)

Extracted from aquifers through pumping wells and supplied for domestic use industry and agriculture

With increased withdrawal of groundwater the quality of groundwater has been continuously deteriorating

The crop yield has increased by in dry land farming

The soil loss due to erosion was brought down

Large extents of barren hill slopes were covered by vegetation

Large tracts of marginal lands brought under dry land Horticulture

Development of Agro-Horti and Agro-Forestry systems

Water resources were harvested through nala bunds farm ponds gully embankments

Regeneration of grass lands for more fodder and grass

The income of farmers increased considerably

Benefits derived from Watershed Methodology

MONITORING THE WATERSHEDThe following parameters have been considered for monitoring and evaluation purpose which could be derived from satellite data

Cropped Area Changes in areal extent of agricultural crops

Plantations Increase in horticultural and forest plantations

Wastelands Change in areal extent

Alternate Use Switch over of agricultural land

Waterbody Change in number and areal extent

Biomass Overall changes in biomass canopy cover productivity

05032023

POINTS TO BE CONSIDERED BEFORE TAKING UP IMPACT STUDIES

1 SATELLITE IMAGES SHOULD BE OBTAINED ONLY AFTER CONSIDERABLE TIME AFTER IMPLEMENTATION( 6-10 YEARS)

2 CONDITIONS SHOULD BE SIMILAR FOR PRE AND POST TREATMENT

RAINFALL- QUANTUMDISTRIBUTION ETC SOWING SEASON- EARLYDELAY

3 AVAILABILTY OF SATELLITE DATA FOR REQUIRED DATES

4 RESOLUTION OF SATELLITE DATA-

SHOULD BE SAME FOR PRE AND POST
