| Abstract: | Impact of anthropogenic activities has led to significant changes in riverbeds over a period of time. The objective of the study was to monitor the land use land cover (LULC) of Yamuna riverbed in Delhi and to assess the changes due to natural and anthropogenic activities. The maximum likelihood classification was carried out by using March 1977, April 1999, April 2002 and February 2009 imageries. An overall accuracy of LULC classification of 2009 imagery was around 88.6% based on ground truth data. A significant reduction in the main river course and increase in agricultural activities as well as built up were observed in remote sensing analysis as an outcome of riverbed encroachments. The changed scenario of riverbed not only stresses the riverine ecosystem but also jeopardizes the future consequences on river hydraulics. |
