Soil Moisture Dynamics, Runoff Generation, And Streamflow Response In A Prairie Hillslope See System, Texas

Abstract

Seeps are unique habitats that provide important hydrologic functions, occurring where bedrock or an impermeable surface inhibits the downward flow of groundwater thereby causing water to discharge along a surface. These seeps and their associated headwater streams are critical elements within landscapes and play an important role in the hydrologic cycle. The hydrologic regime of a central Texas prairie hillslope seep system was analyzed with regards to the responses of soil moisture, precipitation, runoff generation, and streamflow response, and whether or not these seeps contained wetlands characteristics. Our study confirms that, during seasonally normal conditions, Muhly seeps and barrens are hydrologically capable of producing runoff and contributing to stream discharge. With this information, we have a better understanding of how these systems behave as intermittent wetlands which could serve to improve habitat management and conservation of riparian areas within Texas.
