The purpose of hydraulic engineering is to design a structure with the proper capacity to divert or remove water from the roadway and pass collected water under the roadway. The design of a hydraulic structure requires knowing how much water is associated with the design storm (hydrology) and calculating the velocity, depth, and type of flow (hydraulics) that must be accounted for in the design.
One of the functions of the National Hydraulic Team (NHT) is to provide FHWA offices with technical expertise in matters of the hydraulic discipline. This involves providing technical assistance in interpretation of FHWA hydraulic policies, technical publications, software, and recommended guidance in solving difficult and unusual drainage problems. We also are instrumental in the deployment of new technologies and research to the Divisions and state DOT partners.
