Identifying Hydrologic Processes in Agricultural Watersheds Using Precipitation-Runoff Models
Joshua I. Linard, David M. Wolock, Richard M. T. Webb, Michael Wieczorek
2009, Scientific Investigations Report 2009-5126
Understanding the fate and transport of agricultural chemicals applied to agricultural fields will assist in designing the most effective strategies to prevent water-quality impairments. At a watershed scale, the processes controlling the fate and transport of agricultural chemicals are generally understood only conceptually. To examine the applicability of conceptual models...
Water Quality and Hydrology of Silver Lake, Barron County, Wisconsin, With Special Emphasis on Responses of a Terminal Lake to Changes in Phosphorus Loading and Water Level
Dale M. Robertson, William J. Rose, Faith A. Fitzpatrick
2009, Scientific Investigations Report 2009-5077
Silver Lake is typically an oligotrophic-to-mesotrophic, soft-water, terminal lake in northwestern Wisconsin. A terminal lake is a closed-basin lake with surface-water inflows but no surface-water outflows to other water bodies. After several years with above-normal precipitation, very high water levels caused flooding of several buildings near the lake and erosion...
Multi-state succession in wetlands: a novel use of state and transition models
Christa L. Zweig, Wiley M. Kitchens
2009, Ecology (90) 1900-1909
The complexity of ecosystems and mechanisms of succession are often simplified by linear and mathematical models used to understand and predict system behavior. Such models often do not incorporate multivariate, nonlinear feedbacks in pattern and process that include multiple scales of organization inherent within real-world...
