Topic: IRIC Pilot Applications for the Potomac River Using BathyLidar Data

Presenter: Jonathan Nelson, USGS

This presentation will illustrate how detailed topographicbathymetric LiDAR data sets can be used within the USGS iRIC (International River Interface Cooperative) software package to compute detailed flow and particle tracking simulations across a range of length and time scales, including capturing the effects of local unsteadiness and turbulent mixing.

While results will concentrate on the recent Potomac River data set, other examples will also be included to illustrate a small subset of iRIC capabilities, including a brief discussion of the new iRICMI model coupling tools, which allow end users to couple ground water, hillslope runoff, tracking and other subsidiary models with detailed river models globally and at the time step level.

iRIC is a river flow and riverbed variation analysis software package which combines the functionality of MD_SWMS (MultiDimensional SurfaceWater Modeling System) developed by the USGS, and RICNays, developed by the Foundation of Hokkaido River Disaster Prevention Research Center.
