Climate Impact On Groundwater Flow Processes In The Cedar Creek Watershed And Cedarburg Bog, Jackson Graham

Theses and Dissertations

A local-scale groundwater-flow model of the Cedar Creek Watershed and Cedarburg Bog area was constructed to determine the effects of future changes in temperature and precipitation on water resources. The Cedar Creek Watershed is a 330 km2 sub-basin of the Milwaukee River Watershed located about 30 km north of Milwaukee. The importance of this watershed lies in its location at the sub-continental divide separating the Mississippi River Basin from the Great Lakes Basin. The coupled steady-state and transient flow models incorporate interaction between surface water features and groundwater-surface water interactions. The 4 layer model simulates the influence of recharge on …

Simulating Recharge In A Wisconsin Watershed: The Effect Of Sub Annual Precipitation Patterns, Alice Egan

Theses and Dissertations

A watershed, the Prairie River in north-central Wisconsin was used to analyze why the same annual precipitation generates variable annual recharge rates. Global Climate Models (GCMs) with three greenhouse gas emission scenarios (B1, A1B and A2) for two time series 2047-2065 and 2082-2100 were used to examine the annual and monthly differences between the Prairie River watershed future projections and the Prairie River watershed historical record, 1954-2009. The USGS soil water balance (SWB) model was used to calculate recharge.

In the Prairie River watershed, there is a strong correlation (R²=0.84) between growing season recharge and growing season precipitation, and there …

Comparative Recharge Rates Of Isolated And Riverine Wetlands, Chenille Hargrove Williams

Theses and Dissertations

Isolated wetlands have a slightly depressed topography surrounded by an upland area. There is no direct surface water connection, as with riverine wetlands; however, there is a groundwater connection that allows isolated wetlands to have similar hydrologic functions to riverine wetlands. This study sought to compare surficial aquifer groundwater recharge rates of several isolated and riverine wetlands in the Coastal Plain of the Carolinas by evaluating soil characteristics, water table fluctuations, and precipitation from January 2012 - September 2012. Data analysis indicated no significant difference in mean recharge rates between the isolated and riverine wetlands at each study site. Whereas …
