Summary
Many hydrological and geochemical processes associated with lakes and wetlands are poorly understood. Characteristics of wind and vapor profiles over lakes, which are basic controls on evaporation, have been studied in detail for only a few large reservoirs in the western United States. Many commonly used methods of estimating surface runoff to lakes and wetlands, are inaccurate. Hydrogeologic controls on seepage to and from all surface-water bodies have not been studied adequately, either from theoretical or field perspectives. Research on these components of lake and wetland hydrology is especially critical to individuals responsible for management, protection, and restoration of these resources. The major objective of the problem of lake hydrology research is to gain understanding of the basic principles controlling the interaction of lakes and ground water, including associated chemical fluxes. The project emphasizes integration of theoretical and experiment field work. Although research emphasis is on ground water, the project includes state-of-the-art studies of the atmospheric and surface-water components of lake hydrology, as needed in the evaluation of the ground-water component. Evaluation of error in hydrologic methodology for the various aspects of lake water balances is an integral part of the research effort.
