Flood Control and Hydraulic Structures

With increasing uncertainties and changing climates, flood control through carefully planned, designed and operated hydraulic structures play a critical role in saving lives and protecting properties and communities. Our experts in flood control and major hydraulic structures engineering are experienced with a variety of structures and facilities including levees, dams, canals, pump stations, detention basins and impoundments as well as intake, flow diversion and outlet structures. 

WSP USA provides flood risk assessment, complex coastal and riverine hydrologic and hydraulic modeling, planning and design of hydraulic control structures and facilities, floodplain analysis and flood forecasting, FEMA mapping and CLOMR/LOMR preparation.


Our team has a successful track record working with private and public clients for both large and small hydraulic structures including dams, levees and large water impoundments. We provide technical services and expertise that is vital to the success of any hydraulic structures including:
