Watershed Analysis using GIS

The course is designed for explore and download of SRTM Digital Elevation Model (DEM) data of specific study area. The Shuttle Radar Topography Mission (SRTM) DEM is unique product which was produced by NASA and NGA in cooperation with German and Italian space agency. Further, using of hydrology tools of ArcGIS, watershed area is delineated for given pour point and identification of streamline network with stream order within watershed area. Watershed is the area of land on the earth surface that collects and drains all the rainfall within its coverage area and streams to a common outlet along the high order stream channel. And the term pour point is the lowest point in term of elevation along the streamline within watershed at which all the water flows out of the watershed area. The analyzed data is used for estimation of storage area and storage volume capacities at a series of elevation range (a variable dam heights). The course is ended with the preparation of an informative and comprehensive watershed area map layout design. The proper compilation of each analyzed data into ArcGIS platform finally concluded into a better and informative map design and preparation. The process of map composition starts with preparing a layout for the map. Apart from the data, a map has certain other things that make map a package of effective and clear communication.
