Stormwater and Floodplain Management
& Flood Model
Overland Flow Model
Robust Runoff Routing
(Los Angeles County)
It is the job of Stormwater and Floodplain Manager to plan, develop and manage our resources that provide a response to the hydrologic cycle and our part in it. Water evaporates, falls from the skies onto urban, rural and forested lands, and runs off into streams, rivers and lakes, as well as onto roofs, roads and urban landscapes and is utilisedutilizedutilised by those who live there.
You design the physical infrastructure necessary to meet the needs of society and to preserve the natural environment, and model its ability to withstand the extremes of the hydrologic cycle.
What customers say about using XP Solutions for stormwater management:
"We purchased xpswmm and xp2D for use on a specific urban watershed stormwater management plan project which required the evaluation of the extent of flooding for the 1-through 100-year storm events. Without xpswmm, the extent and height of flooding once water began to surcharge the system were difficult to quantify because of the need to use theoretical ponding nodes and street overflow routes. xpswmm and xp2D tackles this issue head-on and provides a powerful analytic and public informational tool by allowing for the creation of flood extent maps similar to floodplain maps for open channel systems. We have been pleased with the software and are now using it on additional projects."

When dealing with everything from site runoff reduction to water quality concerns to master plans, Stormwater Managers face face many challenges:
- What impact will sustainable drainage stormwater controls have on the water quantity and quality in my system?
- How will I meet regulatory requirements for stormwater?
- How to deliver quality work that can be easily quantified to clients and reviewing agencies?
- Should we build more infrastructure to handle increased flows or require stormwater controls on-site?
- How will we approach stormwater treatment?
With extreme weather conditions being an ever-present possibility, Floodplain Managers must constantly evaluate the resilience of their flood management systems.
- Will dams and levys withstand heavy floods?
- What happens if they don't?
- During massive storms, which homes and businesses will be in the most danger?
- How can people evacuate and which route is the safest for emergency teams?
- Deliver accurate, realistic, complete system analysis, from runoff to pipes and open channels and flooding to water quality
- Yield robust, integrated, fully-dynamic 1D and 2D hydrologic and hydraulic simulations that use the latest analysis methods and provide a realistic view of storm and flood waters
- Meet municipal and federal requirements and benchmark tests, including the U.S. Federal Emergency Management Association and the U.K.’s Environment Agency
- Assist in Emergency Action Planning by providing evacuation route planning and time to inundation information
