-Watershed delineation is a process for creating an area from which runoff is collected and drained through common convergence point for a study area.
Simmerized Watershed Delineation Steps Using ArcGIS
Step 1: Fill DEM sinks
Step 2: Determining flow direction
Step 3: Flow Accumulation
Step 4: Snapping Pour point and
Step 5: Watershed Delineation
Factors Considered for Watershed Delineation
-Biophysical elements (Climate, Water, Drainage, Soil ,Vegetation, Slope, Status of erosion, LULC, Land capability classes etC.)
-Socio-economic elements (People, Farming system, Social set up, Economic activities, Vulnerability profile, Gender etc.)
-Softwares used for this tutorial are Global Mapper, ArcGIS, DEM, Google Earth
