hydraulic and hydrologic analysis

WSP USA’s water resources team is at the forefront of hydrologic and hydraulic analyses, providing comprehensive services for flood mitigation and resiliency projects, transportation hydraulics, and hydraulic structures such as dams and reservoirs. We offer technical excellence and strong regulatory and public involvement experience to provide effective solutions for the most complex issues.


WSP is an industry leader in performing comprehensive, state of the practice hydraulic and hydrologic analyses throughout the U.S.

Our engineers have expertise in a wide array of the latest tools and models, ranging from simple to sophisticated. This expertise allows us to provide high-quality services across a varied range of applications. Using these tools together with high-quality data, our engineers determine flood levels, discharges, flow velocities and other key hydraulic parameters for existing conditions and proposed designs.

Our comprehensive approach and suite of modeling tools increase the level of confidence and reduce conservatism in our analyses, resulting in efficient designs that satisfy applicable guidelines and regulations, while reducing project costs.


Addressing a Changing Climate

Climate trends are increasing flood risks in many areas. Our modeling team routinely supports our clients by helping them understand and adapt to these new conditions.

We quantify the impacts of sea level rise, changing precipitation patterns and intensifying flood events. By assessing increasing flood risks and identifying at-risk assets, we create resilient cities, infrastructure and systems through an integrated, multidisciplinary approach.
