Abstract: India is extremely liable to floods and out of the overall region of 329 mha, over 40 mha is flood prone. Floods are recurrent phenomenon, which cause huge loss of lives and damage to livelihood system, loss of domestic animals, property, infrastructure and public utilities. It is a cause for great concern that the increasing trends are noticed to be high in connection with flood damages. This can be attributed to many reasons including rapid increase in population & urbanization coupled with growing developmental and economic activities in the floodplains and global warming. Continuing and large scale loss of lives and damage to public and private property due to floods indicate that it still need to develop an effective response to floods. The present study aims to strengthen the existing criteria for flood preparedness and to minimize the risk analysis in Kapila River floodplains of Nanjangud. Limited field visits are carried out during & after flood impacts and field photographs has been effectively collected. Survey of India (SoI) topomap, IRS-1D, PAN+LISS-III and ASTER G-DEM satellite data are processed through GIS environment. It is hoped that this humble effort will prove useful to decision makers in formulating effective Flood Management Plans in the future for similar geological terrains.
