Abstract: The effect of the pollution load generated internally from a reservoir on the effectiveness of an eutrophication control plan is significant and has gained increasing attention recently. Accurate estimation of the internal load is difficult because of its spatial and temporal variation. A procedure using a dynamic spatial modeling approach is proposed to improve the estimation. A case study of Posan off-stream reservoir is described to demonstrate the implementation of the procedure for data collection and model preparation, field sampling planning and investigation, laboratory analysis for phosphorus releasing rates, model integration of AGNPS and WASP, calibration and verification of the integrated model, and the internal load estimation. The procedure is expected to provide appropriate temporal and spatial phosphorus internal load estimation for an off-stream reservoir. (C) 1998 Elsevier Science Ltd. All rights reserved.
