GIS technology coupled with remote sensing can be used to understand and predict the changes that may lead to floods.
Abstract: Flood is a complex outcome of an interface between geological, physiographical, hydrological, meteorological and anthropogenic dynamics. It mandates high computational techniques for the analysis of a large volume of hierarchical pictorial data. GIS technology, inseparably interleaved with remote sensing, helps to panoramically beam complex issues involving river floods and the feasibility of detecting and mitigating them.
