Calibration of a Field-Scale and a Watershed-Scale SVAT Models for prairie wetland in Florida

Improved quantification of the energy, moisture, and momentum fluxes at the land atmosphere interface is critical to studies in hydrology, meteorology, and biogeosciences. Soil Vegetation Atmosphere Transfer (SVAT) models have historically been used within the Atmospheric models to provide estimates of the land surface fluxes. SVAT models. They simulate 1-D energy and moisture transport at the land surface with one or more canopy layers and in the vadose-zone with multiple soil layers. They differ in the number of layers, the treatment of interception and in the methodologies used to estimate canopy ET, soil temperature, and soil moisture transport, depending on their intended applications. In this study, two SVAT models were calibrated for a highly variable convective atmospheric conditions and the atypical hydrogeology of the southeastern US. The two models, Common Land Model and the Land Surface Process model, are structurally different and were developed for different applications. This study examines the utility of increased sophistication in parameterization as it relates to differences in scale and their application in the southeastern US.
