Baseflow is an important component of streamflow and watershed hydrologic budgets, yet quantifying the baseflow fraction of tile drainage has rarely been reported. In this study, we used two common hydrograph separation methods (local minimum method, recursive digital filter) to separate the discharge hydrographs from three drainage district tiles located in Iowa. Based on data collected from 2009...
The prairie pothole region covers 700,000 km2 of North America and once contained millions of pothole wetlands but agricultural drainage was used to convert many these wetlands to agriculture. Termed “drained wetlands” in this study, groundwater hydrology and quality beneath these pothole depressions is poorly understood. In this study we characterized water table levels and nutrient concentrations...
