Abstract

Karachi is a strategic city in Pakistan that was once known as a fishing village. An increase in industrialization and urbanization had been seen in the city. Karachi’s land use, land cover as well as drainage networks have been changed because of Industrialization and urbanization. Flooding in Karachi because of late summer season monsoon rainfall has resulted in urban flooding. Poor urban planning and management had severely affected both rivers and linked tributaries. This study used secondary data that shows changes in LULC and poorly maintained drainage networks are the factors that caused urban flooding in Karachi. DEM, GIS, and SRTM have been used to mark the boundaries of Karachi and drainage networks on the digitized map. These maps could be utilized for improving the natural drainage networks as well as flood mitigation and preparedness measures. This study may provide a guideline to disaster planning, management, and development authorities.
