Abstract

The fully distributed TOPLATS (TOPographically-based Land-Atmosphere Transfer Scheme) hydrological model was used to explore the detailed representation of the dynamics of hydrological processes in the Little Washita River watershed in Oklahoma, so that the effect of aggregation at the macroscale can be determined. Although the predicted soil moisture patterns were similar to ESTAR microwave radiometer measurements, there were some nonrandom spatial patterns of model errors corresponding quite closely to the spatial soil pattern in the watershed. A better approach would be to use the statistical mode of TOPLATS for long-term modeling and then fine-tune the spatial soil moisture variation in specific time periods using the distributed mode.
