Abstract— This study aimed at modelling the hydrologic processes of Paya Indah wetlands (PIW). The model includes surface water inflows and outflows, daily rainfall, potential evapotranspiration (ET), and groundwater seepage. An integrated surface water/groundwater systems approach was developed using MIKE SHE software. At this stage of PIW modelling process we calibrated surface water level and groundwater head levels to the extent that permitted by the available data. The model was simulated for both dry and wet seasons. The multi-criteria results reveal that the model performance is satisfactory.
