Urban development is a sign of improved life style and socio economic up gradation too, but if it is not well planned it brings adverse impact to the environment. Bhopal city is no exception to it, in the name of development and progress the decision makers are overlooking the basic problems, which has resulted in unplanned growth and invites intervention of Scientists, Engineers, Planners and Administrators
Water resources have become the casualty of intensive urbanization. Pollution of water bodies, lakes, rivers and contamination of precious groundwater has resulted in various problems. Urban population is increasing by leaps and bounds, so as the pollution of water resources, all due to anthropogenic activities. The beautiful scenario of urban development has an ugly face on the other side of the coin. The infiltration of sewage water to groundwater has resulted into high nitrate content in the major parts of the city. Unmanaged filth and refuse from the slums are the main source of pollution of water resources.
The carrying capacity of the water resources within the development area itself should be calculated and the ways of its recharging (utilizing maximum precipitation) before preparation of development plan of any urban area for its sustainable development, rather than importing water from a long distance which will definitely disturb the Eco system of that area.
The interpretation of satellite data in conjunction with sufficient ground truth information, it is possible to derive significant information in Geology, Geomorphology, Soil, Structural pattern and recharge conditions which ultimately defines the ground water regime based on various iteration and analysis on different variables undertaken for present study.
The major objective of the study being:
- To demarcate good ground water potential area, which can be conserved for the future.
- To delineate surface water bodies and suitable areas for sub surface storage depending upon the area.
- Detailed drogeomorphological studies for the assessment of land use, land capability on water shed basis.
- Preparation of water resources action plan for overall impact assessment due to urbanization, excessive exploitation of water resources and suggest suitable methods for sewage and solid waste disposal.
