Abstract
The study presents geomorphological and land use mapping of the north western part of Ishwardi Upazila under Pabna district, Bangladesh. The objective of the research was to identify geomorphologicalunits and to prepare geomorphological and land use mapping based on remote sensing data and extensive field work. The satellite images of SPOT (Band 4) and Landsat TM-2012 were used for interpretation of geomorphological units. Land use elements are mapped using SPOT satellite images (Band 4) incorporated with field observation data.The study area consists of active channels, abandon channels, natural levees, flood plains, flood basins and lateral channel bars. The results revealed the need for regional and local land use policy revision employing a multi-disciplinary approach for sustainable development. The study advocates for the integration of geological factor in initial for land use planning in order to avoid damage of property and loss of lives. However, the study calls for further research work using different and longer data sets.
