ABSTRACT
Flooding is one of the serious natural hazards in the world (Seyedeh 2008), and accounts for 40% of deaths caused by natural disasters, with most flood events occurring in developing tropical regions of India. About 4,00,000 km2 of land is prone to flooding, which is about 12% of the total geographical area of 32,80,000 km2. About 1,20,000 km2 of the flood-prone land has been provided with some reasonable protection against floods by providing flood embankments and drainage channels (Apte 2009). Advances in Geographical Information System (GIS) and Remote-Sensing (RS) technologies, and a new satellite platform developed by recently launched sensors have widened the application of satellite data. These technologies can be applied to validate flood inundation models (Samarsinghel 2010). GIS not only facilitates model development and analysis, but also is critical in helping local residents and municipal engineers to understand the existing flooding extent, as well as its potential changes, as a result of the proposed improvements (Baumann 2011).
