| Summary: | Malacca Straits is recognized worldwide due to its importance as the busiest
waterway in the world. The environmental profile of the Malacca Straits points to
certain stresses in the ecosystem due to pollution load. Pollutants from land-based
sources are probably the most pressing environmental problem. Wastes from
agricultural, industrial, and domestic source discharge directly into the Straits or
indirectly via rivers, which flow into the Straits. As far as land based pollution is
concerned, study on river basin is important. The Malacca River basin is of the rivers
flowing into the Straits of Malacca. Geographic information System (GIS) was used to map the water pollution scenario
due to its ability to analyze spatial and temporal data. Beside that, correlation
coefficient method was used to determine the relationship and variation between
rainfall and water quality parameters. Six parameters selected for this study. namely.
Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD),
Ammoniacal Nitrogen. pH, Suspended Solid (SS), and Dissolved Oxygen (DO). The
output of this study consists of water quality database. maps, and graphs on the water
quality variations. The important of this study is the application of GIS technology in
monitoring water quality. Technology plays an important role for effective
environmental management. |
