When a case requires and expert in storm drain system analysis, having a seasoned hydrologist can be the key to a comprehensive understanding of the case. At WRCS (Water Resources Consulting Services), we bring over 35 years of unparalleled expertise, offering top-tier professional witness services tailored to meet the unique demands of your case.

Storm Drain Systems:

WRCS has been modeling storm drain systems for over 30 years. We have worked with numerous storm drain hydraulics models, both one- and two-dimensional, for the analysis of these, sometimes expansive, sometimes highly complex, systems. Our advantage in having experience with so many of these storm drain system computer models is that we can use most pre-existing models for the storm drain system at hand and rerun them to look at “what if” scenarios pertinent to the case.

The highest concentration of flood damages occur in connection with urban flood control and storm drain systems. Storm drain systems are normally designed to provide a certain level of flood protection, e.g., 5-, 10-, 50-, or 100-year protection. Some systems, however, are undersized or under-maintained, as per their own intended level of protection and maintenance standards. And what about that “act of God” flood? Does it apply? We, here at WRCS, can tell you the answer to those questions.
