%X A catchment-scale distributed hydrological model is developed for coupled simulation of surface and subsurface runoffs.Interactions between surface runoff,soil water and groundwater are realistically simulated.In particular,characteristics of the lake-catchment system are considered in the model so that the model is more flexible to be applicable to lake catchments than other existing models.The model can simulate multiple river sub-catchments within a lake catchment,as well as direct overland flow and subsurface flow into the lake.Preliminary model application was undertaken in Fuxianhu Lake catchment,Yunnan Province,China.Comparison of predicted results with the observed ones in terms of stream flow,soil water content and groundwater level demonstrates a satisfactory agreement.The modelled results are also compared with those from the SCS model to further validate the model.The model can be used to investigate various hydrological processes of the lake-catchment system,to simulate the response of catchment hydrological processes to the change of natural conditions or human activities,and to explore the interactions between surface runoff,groundwater and lake.The model would also be a useful tool for water balance analysis of the lake-catchment system to facilitate water resources management.
