Abstract
In the present study the issue of temporal changes of surface water use pattern has been evaluated by identifying hydrological features and water use of a very important watershed of Swarnarekha River nurturing the major urban area of Gwalior and adjoining areas of Madhya Pradesh using multi-spectral satellite and latest GIS technologies. The satellite images of Landsat 7 (2003), LISS III (2009) and Landsat 8 (2014) have been analyzed for the change detection of features. Images with high classification accuracies have enabled demarcating the changes in water spread areas successively with time from the year 2003 to 2014. The pattern of major drainage lines show that the majority of water requirements of Gwalior are met by the river Swarnarekha. The catchment of the river covers around 250 sq km. This includes urban areas of Gwalior, nearby villages and small settlements. Thus the precipitated water moves overland through surface drainage lines and through the vadose zone to contribute to this river. A gradual temporal change in the water spread area has been noticed. The surface detention of rain water indicates that there is a decrease in hydraulic conductivity of the soil causing depletion of subsurface storages. However, the low drainage density and moderately fine drainage texture indicates the presence of permeable soil strata. The surface water reservoir of Gwalior is Khiraoli, the hydrological state of which is studied by the aid of remote sensing and GIS techniques, it shows that the water spread areas has decreased from the year 2003 to 2014 and the distribution pattern of water has changed.
