Abstract:
Remote Sensing and GIS (Geographic Information System) have been used as emerging tools for monitoring and management of water logging and health of crops. Hence, MODIS V6 and SRTM (Shuttle Radar Topography Mission) data were used for visual interpretation, digital image processing, and mapping of the flood affected mango orchards. Results revealed that low land ecology having 10-20 m elevation and < 1% of slope gradient was severely affected due to flood. Maximum inpact of the flood on mango orchards was observed in Naugachhiya (42.50%) followed by Kharik (26.61%), Gopalpur (12.13%), Bihpur (9.08%), Narayanpur (8.15%), Imailpur (0.92%) and Rangra Chowk (0.61%) blocks of Naugachhiya subdivision. However, water logging in mango orchards in Narayanpur (31.47 km²) and Bihpur blocks (28.13 km2) was limited due to moderately high elevation (35m). These findings may be helpful to trace out the water logged mango orchards in lower Gangetic plain of Bihar.
