The baseflow of the Wolf River (drainage area of 1,200 km2) in northeastern Wisconsin (USA) has declined by over 30% during the last thirty years, whereas climatic, land cover, and soil characteristics of the basin have remained unchanged. Because groundwater basins do not always coincide with surface water basins, estimating groundwater discharge to streams using variables only pertinent to the surface water basin can be ineffective. The purpose of this study is to explain the decline in the baseflow of the Wolf River by developing a multiple regression model. To take into account variables pertaining to the groundwater basin, withdrawal …
Urbanization And Rainfall-Runoff Relationships In The Milwaukee River Basin, Woonsup Choi, Kathryn Nauth, Jinmu Choi, Stefan Becker

To understand the changing rainfall-runoff relationship, the study examined climate and streamflow data in the Milwaukee River Basin in southeastern Wisconsin, of which four catchments with different degrees of urbanization were selected for analysis. This study analyzed temperature, precipitation, and streamflow data with a range of statistical methods, including the Mann-Kendall test, double-mass technique, and quantile regression. Runoff ratios and extreme flow indices were higher in more urbanized catchments. Catchments with long-term data (>40 years) showed significantly increasing runoff ratios and slopes in double mass curves. Overall, there are signs of changes in the rainfall-runoff relationship, but how much …
