Application of geographic information system in water quality study on a road construction project

According to the Malaysian Department of Environment’s (DOE) Water Quality Index for 2005, 52 river basins were polluted. Non point source pollution is a major pollution that has been affecting the quality of these river basins. It has been considered as the major pollution for river as the source c...
