Watershed Hydrology:

WRCS has extensive experience in watershed modeling using several different computer models, from simple rainfall-runoff algorithms to complex geo-spatial numerical modeling systems. We can analyze models developed by government agencies or design engineers, used as a basis of design for a project, and then re-run the models for various watershed conditions and storm frequencies.

Watershed hydrology is the study of the rainfall–runoff process, or how rainfall occurring over a watershed will produce a specific flood hydrograph. With watershed hydrology we can model this process to determine the volume of runoff produced by a storm, the shape and peak flow of its flood hydrograph, and what the hydrograph will look like at a downstream location. By adjusting watershed basin parameters or rainfall patterns we can analyze the effects of watershed development or determine what the 100-year flood, or any design flood, would look like at any given location.

Watershed Hydrology Expert Witness Featured Cases

Flood Operations of Two Army Corps of Engineers Reservoirs During Hurricane Harvey Evaluated for Downstream Impacts in Two Cases; Beaumont, Texas. Gate operations and inflow-outflow hydrographs were analyzed at Sam Rayburn and Town Bluff Reservoirs. Dam releases were hydrologically tracked 100-miles downstream, and over four days travel time, to Beaumont. Flood impacts on residential neighborhoods and Neches Port terminals were evaluated by flood hydrograph separation of the hurricane’s total flood flows coming off of numerous tributaries and watershed areas along the lower Neches River.
