In this study, Water Quality Analysis Simulation Program (WASP) was used to simulate the impacts of various phosphorus (P) load reduction scenarios on nutrient concentrations in Lake Uluabat, a Ramsar site (a wetland of international importance designated under the Ramsar Convention), including sediment dredging options and source reduction. The model was calibrated for various water constituents including ortho-phosphate (PO43-) and nitrate (NO3-). The calibrated model was used as a management tool to predict the nutrient concentrations and water quality conditions in the lake for different P management alternatives. Results indicated that due to heavy sediment load, sediment dredging may be required to improve the water quality and control eutrophication in short term. However, it was observed that partial sediment dredging combined with other P load reduction alternatives could have similar overall effects compared to full sediment dredging in long term. Therefore, partial sediment dredging could be used as an alternative P control strategy when applied together with other P load control options. (C) 2012 Elsevier GmbH. All rights reserved.
