The cell-based\nmodel is developed by considering direct runoff based on the Soil Conservation Service - Curve Number (SCSCN)\nmethod and surplus runoff based on the Thornthwaite water balance theory. After calibration and validation,\nthe model is used to predict LVR discharge under future climate and land-cover changes. The hydrologic\nsimulation results reveal climate change as the dominant factor and land-cover change as a secondary factor in\nregulating future river discharge. The combined effects of climate and land-cover changes will slightly increase\nriver discharge in summer but substantially decrease discharge in winter. This impact on water resources deserves\nattention in climate change adaptation planning. \n\nThis dataset is associated with the following publication:\nChen, H., S. Tong, H. Yang, and J. Yang.
