![]() ![]() Water quality constituents that came under close scrutiny for the modeling included Biochemical Oxygen Demand (BOD 5), Total Suspended Solids (TSS), Ammoniacal Nitrogen (AN), Nitrate (NO 3 -) and Phosphorous (P). The model was then calibrated based on data collected on-site during high-flow conditions. The Event Mean Concentration (EMC) was derived from typical land use classifications coherent to the specific area, whereas the runoff volume was calculated from precipitation using the Rational Equation. ![]() The objective of this study was to identify sources of pollution along Bertam River sub-catchment related to a proposed agricultural development and its impacts towards ambient water quality from surface runoff with primary organic contribution from the fertilizers used. Non-point source pollution (NPSP) modeling using QUAL2E however requires the integration of hydraulic and hydrological principles not apparent to the model. The use of the model for point-source evaluation is relatively straightforward, as the model has the in-built provisions for these types of applications. QUAL2E is a widely used and accepted model in Malaysia in relation to impact assessments, discharge permit allocations and river rehabilitation studies. ![]()
