Title:

Application and Validation Study of the HEC-RAS-RVSM Model to the Sacramento River 

Author(s):

Zhonglong Zhang, Billy Johnson, Junna Wang, and Blair Greimann

Purpose/Abstract:

The riparian vegetation simulation module (RVSM) was developed and integrated into the Hydrologic Engineering Center-River Analysis System (HEC-RAS) to predict spatially explicit seed dispersal, seedling establishment, plant growth, and mortality in response to riverine hydraulic conditions. The HEC-RAS-RVSM model is capable of predicting dynamic hydraulic roughness and simulating the interactions of flow and riparian vegetation on floodplains. In this study, the HEC-RAS-RVSM was applied to the Sacramento River reach to evaluate its modeling capabilities with regard to vegetation changes and interactions between flow and riparian vegetation dynamics. The purpose of this Ecosystem Management and Restoration Research Program (EMRRP) technical note is to document the validation study of the HEC-RAS-RVSM model for the Sacramento River reach and provide a user guide for applying this tool.
