Research Demonstration of a Decomposition Approach for Large-Scale, Coupled Surface-Subsurface Watershed Model Calibration and Validation

摘要

This paper proposed a decomposition approach in order to calibration and validate a large-scale, coupled surface-subsurface watershed model in an effective and efficient manner. With this approach, the entire watershed system is subdivided into several sub-domain systems with existing channels as the "cut" boundary between sub-domains. This paper uses a hypothetical example as a proof of concept to verify the decomposition approach. It also describes how the approach was applied to a watershed system in South Florida that covers an area over 8,000 square miles as part of a research demonstration project.
