Environmental Impact Assessment for Dam Construction Using GIS/Remote Sensing
Track: Environment Management
Author(s): Shibani Maitra
GIS and remote sensing play an important role in generating automated spatial data sets and in establishing spatial relationships. The Environmental Impact Assessment for the dam construction on the Man River, Gujarat, India, was performed using GIS and remote sensing software--ARC/INFO and ERDAS IMAGINE. Efficient management of irrigation water was suggested using recent information of the command area by processing imageries through ERDAS IMAGINE. The impact of the dam in terms of submergence area and command area was computed to assess the net benefit to society. GIS can also help in site selection for the rehabilitation and infrastructure location.
