Synopsis:

 

Morphometric analysis is more efficiently used in geomorphology and hydrology to interpret basin hydrologic behaviour since Horton’s period. Morphometric analysis concomitant with time of concentration and runoff coefficient are used in this study for the analysis of hydrologic responses of Sirsa basin. Toposheets-based drainage lines are used in this study; while Digital Elevation Model (DEM) data are used for relief and slope analysis. Landsat Thematic Mapper (TM) data was used to prepare land use/cover map. Some selected morphometric parameters and hydrologic behaviour of the basin as well as its twelve sub-basins were analyzed. The overall analysis of the whole basin indicates low to moderate peak flood. A sub-basin wise analysis indicates that only three higher order downstream sub-basins are flood prone. The study is very useful for watershed prioritization.
