Project ID: 1762
Principal Investigator: D. Nathan Bradley

Research Question

How would the Bureau of Reclamation benefit by collaborating with the U.S. Geological Survey (USGS) to integrate SRH-2D, Reclamation's hydraulic and sediment transport model, into the International River Interface Cooperative (iRIC) river simulation framework?
The iRIC project is a collection of tools for preparing, executing, calibrating, and analyzing simulations of river hydraulics and sediment transport (http://i-ric.org/en/index.html). By incorporating SRH-2D into the modeling framework as a solver, Reclamation would gain access to iRIC's model development and analysis tools while still retaining control over our flow and sediment transport code. iRIC is free and could either replace or complement the commercial software Reclamation currently uses to prepare and analyze hydraulic models.

Need and Benefit

Need:
Reclamation uses SRH-2D to model river hydraulics and sediment transport. Among other things, these models can be used to quantify aquatic habitat, evaluate proposed river restoration designs, identify areas of scour and fill, to predict changes to channel morphology, and to identify threats to streamside infrastructure.
Broadly speaking, there are three steps to creating a computer model of a river: 1) mesh creation, 2) model execution, and 3) analysis of results. The model mesh defines the model domain and discretizes the physical space represented by the model so that the differential equations describing the flow of water and sediment between mesh elements can be solved numerically. Reclamation currently uses a commercial product called SMS to develop the model mesh and to analyze the model results. iRIC is a free tool that could potentially replace SMS. It includes tools for basic mesh generation, elevation and roughness assignment, and visualization and analysis of model results.
