DDG’s expertise in hydrology and hydraulics engineering was developed through our years of experience with site development activities across the State, together with our support of local municipalities with flood risk assessments and regional drainage improvement projects. From the retrofit of local drainage infrastructure to the design of regional detention facilities, to conveyance improvements in major waterways, to complete drainage designs for thousands of acres of development, we have done it all. Water Resources modeling tools include: USACE HEC-HMS / HEC-RAS, EPA SWMM / PCSWMM, Autodesk Storm and Sanitary Analysis (SSA), Autodesk Storm Sewers, Autodesk Hydraflow / Hydraflow Express, Streamline Technologies ICPR 4, Bentley PondPack, and FHWA HY-8.
