GIS and Remote Sensing technology is being used to perform the hydrological analysis in support of highway and transportation projects. The delineation of catchment area of all river/drainage is being created using DEM data which is the part of the study to identify the length of the bridge/culvert on the river/drainage. Our watershed analysis highlights problem areas and summarizes current water status largely by the use of Arc GIS software. The resulting information and maps are very beneficial for making accurate management decisions concerning lake quality issues and our reports provide background information for comparison in the future.
