Hydraulic Analysis and Modeling

We regularly apply our modeling capabilities to evaluating many types of engineered and natural systems, including sanitary collection systems, storm sewer networks, natural channels and coastal zones, stormwater management BMPs, drinking water aqueducts, reservoir watersheds, and treatment plants of all sizes.
Most often, we employ hydraulic surge analysis, computational fluid dynamics (CFD), sewer system modeling, and water quality modeling to help municipalities:

• create water and sewer master plans
• meet EPA regulatory requirements
• eliminate combined sewer overflows (CSO)
• identify methods to improve water quality

Practical experience tying models to the real world is what sets us apart. Our modelers specialize in integrating GIS with models using any commercially available software package, and work closely with field engineers, operators, and designers to bridge the gap between models and reality.
We can help you eliminate:

• Low water pressure
• Overloaded pipes
• Poor turnover in tanks
• Excessive water age
• Closed valves
• Short circuiting in tanks
• Pressure surges
• Sewer overflows

Modeling tools enable planning for potential changes in precipitation, increases in sea level and risk from storm surge on infrastructure. In addition to the existing statistical record typically used to size infrastructure for water quality benefits and flood control, Hazen and Sawyer helps clients stay abreast of the most up-to-date research on climate change, and makes use of these forecasts in sustainable long-term planning. Our suite of modeling programs, which include the InfoWorks series by Wallingford Software and the U.S. Army Corps of Engineers’ HEC models, can help control risks associated with climate change. Regardless of the effects of climate change, our modeling expertise produces designs that minimize the impacts of development and infrastructure on the water environment.
