Flooding and Flood Forensics
WRCS has been doing forensic hydrology and hydraulics (H&H) analysis and modeling for over thirty years and in hundreds of cases across the US, Canada and Australia.
Whether your case involves a single historical flood event or a pattern of repeated flooding, WRCS can re-create the hydrology and hydraulics of the flow event using various one- and two- dimensional models. We can then reproduce the flood as if it were to have occurred under various scenarios, whether it’s without bridges or structures, before land development projects, or with different flood control system operation and maintenance standards.
Why Choose WRCS?
We exclusively work in litigation support (Expert Witness Hydrologist) and have done so for 35 years. We have municipal, commercial and professional clients across the U.S., Canada and Australia.
We pride ourselves on our company history of providing unbiased, non-conflicted testimony to both plaintiff and defendant clients.
We are dedicated to helping lawyers, law firms and insurance companies navigate the complex technical world of surface water engineering, and make it understandable to our clients, the judge and the “layman” jury.
No hired guns here.
If there’s problems or weaknesses with your case theory the best thing we can do for you as an expert consultant is to tell you so.
If the technical data backs your case, we will find it, analyze it, model it, report it, and present it with graphics that a judge and jury will understand.
