Geospatial techniques for assessment of bank erosion and accretion in the Marala Alexandria Reach of the River Chenab, Pakistan

Remote Sensing (RS) and Geographical Information Systems (GIS) are widely used for change detection in rivers caused by erosion and accretion. Digital image processing techniques and GIS analysis capabilities are used for detecting temporal variations of erosion and accretion characteristics between...
