Using the hydrologic model mike she to assess disturbance impacts on watershed process and responses across the Southeastern U.S.
A clear understanding of the basic hydrologic processes is needed to restore and manage watersheds across the diverse physiologic gradients in the Southeastern U.S. We evaluated a physically based, spatially distributed watershed hydrologic model called MIKE SHE/MIKE 11 to evaluate disturbance impacts on water use and yield across the region. Long-term forest hydrologic data fiom a southern Appalachian Mountain and a lower coastal plain watershed in South Carolina were used as model inputs. The model captured the temporal and spatial dynamics of shallow groundwater table movement and streamflow. Results suggest climate change and tree removal would have pronounced hydrologic effects; especially during dry periods. We also found that the data parameterization for even small scale distributed watershed-scale modeling remains challenging where spatial subsurface characteristics are often not known. The global change implications on hydrologic processes and response to in the two landscapes are discussed.
