![]() ![]() Maximum erosion and management plan are critical for area at section 2 right bank 1955 to 1973. The satellite images were collected during winter and dry seasons (from November to January), when stream flow is limited for a lower amount of rainfall. Results of long-term river channel migration showed that the land area is influencing with river erosion, settlement area is increasing, vegetation area is decreasing, but sand bar, water body and cultivated land area are oscillating. The maximum likelihood supervised image classification was applied to detect the land-use/land-cover type and identify erosional impact with best accuracy. Normalized difference of water index technique was used for identification of land and water boundary. ![]() ![]() This studied has been carried out in three steps: (1) analyzed migration rate from 1955 to 1973 (2) analyzed migration rate from 1973 to 2016 and (3) assessed migration rate impact on land-use/land-cover change using GIS and RS techniques. Impact assessment on land use/land cover around 5 km from the stream centerline of 1973 was obtained. The standard topographical map of 1955 and satellite images of 1973, 1987, 1999, 20 were used in the study. Alluvium is eroding chronically due to the rushing stream flow therefore, people of this region are poor and government loss national assets each year that reflects the direct effect on the economy. This study has been carried out to evaluate the river shifting and assessment of related effect on the land-use/land-cover using geographic information system (GIS) and remote sensing (RS) techniques between 19 for Padma River at Bangladesh. ![]()
