Paper Title
Watershed Catchment Analysis
Abstract
This study looks into how Geographic Information System (GIS) technology affects ungauged watershed
simulation. At each sampling location, the ground water quality was examined using the APHA standard laboratory
procedure. Using Garmin GPS, the location of the sampling point was ascertained. The Inverse Distance Weighed (IDW)
spatial interpolation method was used to estimate the geographical distribution of ground water parameters and WQI. A map
of potable areas was made using the WQI map. Using Google Earth, the Land Use and Land Class (LULC) image was
produced. The WQI findings are assessed in view of the LULC. The research area's groundwater is safe for domestic use and
drinking, as indicated by the potable index map.
Keywords - Geographic Information System (GIS), ungauged watershed simulation, runoff characteristics, watershed
