ResumoA Coupled Land Atmosphere Simulation Program (CLASP), capable of evaluating surface water-aquifer-atmosphere interactions at the regional scale (up to 400×400 km2), will be used to evaluate paleo-watershed conditions at 6000 BP. The CLASP model couples a single-column vertically-discretized atmospheric model to a finely discretized land surface and subsurface hydrologic model (MODFLOW). The model can be driven by observational data or atmospheric general circulation model (AGCM) output. By simulating the hydrologic fluctuations of individual lakes and streams, the model permits a comprehensive evaluation of paleo AGCM model reconstruction of Holocene climate change at the regional scale. Calculated lake level fluctuations will be compared to lake core records. Preliminary results illustrate the importance of aquifer hydraulic conductivity in paleo-lake level response.
