Abstract

Catchment area and watershed delineation is common task in hydrology. Digital Elevation Models (DEMs)
are spatial grids which are used to automate watershed boundary determination. DEM based Arc-Hydro model was run
on the dataset of the Purna river basin. Several intermediate results were produced while model run and basic parameter
of the Purna river, its catchment area has been defined at the end of model. The result of this study can be used in
Rainfall-Runoff analysis and other advance research on the catchment area. Moreover, it would have support for
decision making on ground and surface water resource, distribution and management. This study of delineated
watershed is further used to calculate hydrologic and topographic features by HEC-geoHMS for developing a RainfallRunoff model in HEC-HMS.
