Abstract:
In the present investigation, the multi-spectral satellite data viz. IRS LISS III(Pre Monsoon), MODIS V6 and SRTM DEM were used for visual interpretation and mapping of flood affected Tal and Diara lands. However, on screen visualization of the cultivated lands were also visualized for the delineation of the cultivated lands. Hence, data of NDVI, water bodies and relief were superimposed to find out area where water logging was remained impact on the cultivated lands. Results revealed that 45.21% of cultivated lands of Sabour, Sultanganj, Nathnagar, Kahagaon and pirpainti block were highly affected due to flood. However, > 85% of the cultivated lands of Ismailpur, Rangra Chowk and Gopalpur block was damaged due to flood. In these blocks, appurtenance of NDVI (value 0.0-0.1) shows the negligible standing crops (except tree). However, there was negligible appearance of the flood was observed in southern part of Sanhaula, Pirpainti and Sahkund block. The present investigation provided an overview, how the geospatial technology can be used to map the cultivated lands of Tal and Diara lands (low land Physiography) in lower Gangetic plain of Bihar.
