When legal matters involve a flooding incident, having a seasoned flooding expert witness can be the key to a comprehensive and unbiased understanding of the case. At WRCS (Water Resources Consulting Services), we bring over 35 years of unparalleled expertise in hydrology, offering top-tier professional witness services tailored to meet the unique demands of your case.

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.
