Abstract:
We extend the ZlotnikOlaguera (2007) lake-aquifer model that considered aquifer anisotropy, flow geometry, and regional flow by including lakebed properties in the groundwater model. Sensitivity analysis shows that previous studies underestimate the importance of lakebed properties that strongly influence lake equilibrium with climate, and more specifically, annual evaporation and precipitation. Incorporating lakebed properties and climate data in the generalized lake-aquifer model at an instrumented site at Alkali Lake provides internally consistent results for lake water budget and salinity. This approach has promise in applications to a system of numerous lakes in the largest vegetated dune field in the Western Hemisphere, the Nebraska Sand Hills.
