The present study deals with the urban geology and environmental problems of the Lahore City in Pakistan. It is based on a set of the following thematic maps at 1:100, 000 scale: geology, urbanisation, engineering geology, land use, flood hazard, and aquifer drawdown depth. The major hazards of the Lahore metropolitan area are air pollution, water pollution, noise pollution, and deforestation, which are the result of rapid population growth as well as poor planning. The Lahore metropolitan area comprises the Early Pleistocene to Recent silty loess and silty clay deposits of the Ravi River. The foundation conditions of the Lahore metropolitan area are generally good. The city suffers from periodic floods during the monsoon season. The pavement and drains accelerate and increase the surface runoff and the peak flood. Unplanned groundwater development in the metropolis has caused a rapid lowering of the water table. Subsequently, the sand is dewatered and the water table has dropped to 7-13 m.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
