Baseflow is a genetic component of stream flow that comes from groundwater storage or other delayed sources. Thus changes in baseflow can significantly impact the quantity and quality of stream flow and fluvial ecosystems. However, unlike a large number of studies that show the effects of climate and land-use changes on peak stream flow, little work to date has addressed their impacts on baseflow. A total of twenty-two urban and rural watersheds in Indiana with different sets of geology, physiography, and land-use were statistically analyzed for trends in annual stream baseflow for past thirty five years. A significant increasing trend in baseflow was found in Indiana's urban and rural watersheds. For watersheds with no significant [...]
