Abstract
 GIS-Based Assessment of Water Quality Parameters in Dhaka Rivers Track: Water Resources Author(s): Sayma Rahman, Faisal Hossain This study demonstrates the value of ArcGIS as a tool to spatially analyze the water quality parameters along the peripheral rivers of Dhaka and thereby arrive at a solution for relocation of the intake point for surface water withdrawal. First, a map of the study area showing Greater Dhaka and the peripheral rivers was developed with the aid of existing themes on rivers, lakes, and present intake point of water withdrawal from the rivers. Sampling locations from GPS data were then digitized along with collected WQ data. Attribute tables were updated with relevant water quality data for the proposed spatial analysis. Next, the WQ parameters at the sampled locations were compared with the Bangladesh standards to identify locations that appeared suitable for water intake. GIS analyses facilitated the derivation of water quality profiles (as a function of distance) along the downstream and upstream reaches of the current intake location.
