Volume : III, Issue : IV, May - 2013 CHANGING COURSE OF SUBARNAREKHA RIVER AND ITS SOCIETAL IMPACT-A CASE STUDY OF GOPIBALLAVPUR-I & II BLOCK USING GEOINFORMATICS JATISANKAR BANDYOPADHYAY , KARTIC BERA AND KRISHNA DUBEY Published By : Laxmi Book Publication Abstract : River is the natural flow of water from upland to plane land. The flow
characteristics depend on the various factors of nature i.e. source of water, climatic
condition, and topography, type of soil, geology, forest, land use / land cover and human
activities. The present paper will focus on course change with societal perspective of
Subarnarekha river in Gopiballavpur- I and II block. The study carried out on
Geoinformatics and field observation environments. Remote Sensing and GIS analysis
and Sinuosity index were used in this study to investigate river meandering and the
associated processes of erosion of river bank and islands, deposition of sediments and
formation of new island. The analysis shows that the Subarnarekha river is a meandering
river. The analysis of Braiding index and result this index the Subarnarekha river are non
braided river in the study area. The lateral erosion on the river banks led to a decrease in
agricultural lands bordering the river banks and decrease in the areas of the river
islands which in turn reduces the agricultural production. The study also suggests that
the local people cause of river shifting and management the natural resources. Keywords : Article : Cite This Article : JATISANKAR BANDYOPADHYAY , KARTIC BERA AND KRISHNA DUBEY, (2013).
