Abstract: The abrupt flood event at Gali Anjaneya Temple in Vrishabhavathi sub watershed disrupts the normal life and cause loss to economy. Main objective of the study is to characterize the morphometric parameters near the Gali Anjaneya Temple, based on toposheets 57/H 9 and 57/H/ 9/1(scale 1:25,000) used for morphometrical analysis. The morphometric parameters were delineated through STRM data using ArcGIS-10.1software. The sub watershed is covering about 34.4 Km2 consists of valleys and plains mainly in urban area. The longest flow path is calculated and found to be 9.3 Km. The study reveals that Remote sensing technology can be employed for . watershed modeling for the study region. The paper highlights the key parameters of watershed such as morphometry and slope analysis by using GIS/RS data.
