Change in Urban Landuse and its Effect on Natural Drainage System: A Geographical Micro Leveled Study of Bhosari Stream (PCMC)

2017 International Journal of Current Research and Review  
Horizontal and vertical expansion of urban areas has been increasing the rate of exploitation of natural resources, systems and their processes. Now a day, urban landuse has also been changing drastically and primarily affecting the natural set up at very micro level and then spreading it for large areas also. The present investigation is trying to highlight the micro leveled changes by such anthropogenetic activities, basically on physical parameters. For this, the paper mainly focusing on

By selecting Bhosari stream from Pimpri Chinchwad Municipal Corporation (PCMC) area, the changes in landuse have been identified and studied with the help remote sensing (RS) tools and techniques. The Google Earth Images for 2005 and 2016 have been analyzed, compared and presented by using GIS technique. For this, information from SOI toposheet has also been taken as a base of the study. The selected basin area, a study area has mainly undertaken by PCMC and by the Defense Authority. The changes in land use have also considerable difference in both these areas. But the effects of such changes have observed differently. In short, specifically in PCMC area, the drastic changes in morphometric systems have been noticed like vanishing the upper order streams, displacement of channel, change in pattern of slope and deposition etc. Because of unnatural changes in drainage, most of the urban places have facing natural calamities. It is therefore necessary to maintain the natural processes and systems particularly in the urban area
