GIS for Handling of Excess Runoff

Abstract
A GIS based hydrological analysis has been carried
out to explore the possibility of diverting storm runoff
generated from the upper catchment safely through a canal
system constructed at the foothill to avoid flooding at
downstream. The study area consisted of Kalapahar-Udyachal
hills (5.38 km sq) in the Kahilipara- Odalbakra area, situated
in the city of Guwahati, Assam. The Digital Elevation Model
(DEM) of the study area was developed from the Survey of
India(SOI) toposheet (1972) using Arcgis software. Watershed
delineation and derivation of required topographic parameters
for for calculating the peak discharge from different
watersheds were done with the help of the generated DEM.
Based on the hydrological analysis, means of safe diversion
of runoff water from hillocks was found out and canal
design of varying geometry capable of handling the peak
discharge suggested.
