HGM Mapping - Groundwater Prospect Mapping at 1:10,000 Scale
Groundwater serves as a major contributor in meeting the demand of water in the Country. With the rapid population growth in Arunachal Pradesh, the demand of water for drinking, domestic and agricultural purposes are increasing day by day and thus the need for groundwater exploration is also increasing.
Groundwater resource is mapped based on derivative techniques involving complex processes. Groundwater prospect maps generated by NRSC under National Rural Drinking Water Program (NRDWP) have their limitations and limited scope because of their scale (50k) and resolution of satellite data used for their preparation.
This study aims at generating Groundwater prospect map of Itanagar township on 1:10,000 scale to locate site for high yielding groundwater wells and to achieve sustainability of groundwater sources in the town.
The study area shows wide range of variation in terms of groundwater prospect. River terraces have the better prospect whereas structural hills have the least prospect.
