Morphometric Analysis of Gandheswari River Basin Area in Bankura District, Westbengal, India, Using GIS Techniques

Morphometry is the measurement of geometry of drainage basin or of a part of it. Significant numerical values for the linear, areal and relief features of the area can be concerned obtained from such measurements. Morphometric analysis plays a vital role to know about hydrological balance of drainage basin. It also provides basic knowledge about climate, bed rock, geological features, runoff, and hydrodynamics of river. Morphometric analysis is a quantitative evolution of drainage system. Gandheswari river is a significant tributary of the river Dwarakeswar. Catchment area of Gandheswari river is highly correlate with morpho tectonics activity. This study we have mainly used quantitative analysis based on secondary data source. Various Governmental reports , journals, newspaper reports, SRTM DEM, Toposheet and Google Earth images has been used for secondary data source generation. Statistical and GIS software has been used for tabulation, computational and map generation. Present study is suggested that the selected river is progressing to reach its maturity level. These studies are very useful for watershed management and maintaining the river health.
