Abstract
The present study used remote sensing images and GIS to identify and measure shoreline changes and its impact on Mangroves in Karachi coast. It has been observed that shoreline change in the study area results from both erosion and accretion processes. The accretion occurred at the southern part of Clifton beach as well as on the northern part of the bundal island. Their distribution throughout the world is affected by climate, salinity of the water, fluctuation of the tides, type of soil in the area and, more recently, by development of tidal wetlands for residential use as well as industrial, i.e. shrimp farms. The information extracted from the remote sensing data using digital enhancement techniques can thus play a key role for monitoring and mapping shoreline changes in the coastal area, which may lead for better understanding of coastal processes and help for planning reclamation work in the Bundal Island, for recreational purpose for the people of Karachi city.
