Description: SWATDRAIN model is being developed by incorporation of subsurface flow model DRAINMOD, into a watershed scale surface flow model, SWAT (Soil and Water Assessment tool) to simulate hydrology and water quality of agricultural watersheds. The model is also capable of simulating hydrology under different agricultural management and climate scenarios. As an application of the SWATDRAIN model the impact of climate change on surface/subsurface flow is being evaluated in the Canagagigue watershed in southwestern Quebec, Canada. Under the assumption of no change in land cover and land management, the model is applied in order to simulate annual, seasonal and monthly changes in surface and subsurface flows at the outlet of the watershed under current and future climate conditions.The climate scenario under consideration in this study for 2015-2044 is based on CGCM2 for future climatic simulation. The simulation results suggest an increase in temperature and precipitation in the region being studied. Those changes result in a significant increase in mean annual and seasonal flow in the watershed.
