Abstract: Numerous hydrologic/water quality models of run-off and soil erosion have been coupled to Geographical Information System (GIS) to determine Non-Point Source (NPS) pollutants from watersheds. Hydrology and water-resource engineering rely on observations of environmental conditions and the accuracy of environmental data. This paper focuses on estimation and monitoring of NPS pollutant loads based on an object-oriented hydro-information system, consisting of Java with JfreeChart package, OGIS compatible MySQL Database and visualisation tools OpenMap. With a grid-based approach, the system takes into account land use, Estimated Mean Concentrations and rainfall data to calculate run-off and NPS pollutant loads.
