Abstract: Urban Water Management is the practice of managing freshwater, wastewater, and storm water as components of a basin-wide management plan. It builds on existing water supply and sanitation considerations within an urban settlement by incorporating urban water management within the scope of the entire river basin. The pervasive problems generated by urban development have prompted, in the present work, to study the spatial extent of urbanization in Bengaluru City and patterns of periodic changes in urban development (systematic/random) in order to develop future plans for (i) urbanization promotion areas, and (ii) urbanization control areas. Remote Sensing, using USGS (U.S. Geological Survey) Landsat8 maps, supervised classification of the Urban Sprawl has been done for during 1900 – 2010, specifically after 2000. This Work presents the following: (i) Impact of Land use/cover on ground water level using well location data and (ii) Morphometric analysis of Bengaluru City. The outcome of the study shows drastic growth results in urbanization and depletion of ground water levels in the area that has been discussed briefly. Other relative outcomes like declining trend of rainfall and rise of sand mining in local vicinity has been also discussed. Research on this kind of work will (i) improve water supply and consumption efficiency (ii) Upgrade drinking water quality and wastewater treatment (iii) Increase economic efficiency of services to sustain operations and investments for water, wastewater, and storm water management, and (iv) engage communities to reflect their needs and knowledge for water management.
Keywords: Land Use Cover Change, Buffer Analysis, Uncertainty Analysis and Urban Sprawl.
