Hydraulic Reports and Design-Build Projects
Design-build projects present design and schedule challenges so PEOs shall coordinate the hydraulic design with both the RHE and State […]
Hydraulics
Various types of drainage facilities are required to protect the highway against surface and subsurface water. Drainage facilities must be designed to convey the water across, along, or away from the highway in the most economical, efficient, and safe manner without damaging the highway or adjacent property. The purpose of this manual is to provide detailed information on the subjects of hydrologic and hydraulic analysis related to highway design. This manual should be used in conjunction with the Washington State Department of Transportation (WSDOT) Highway Runoff Manual and the WSDOT Design Manual, specifically Section 1210.
Hydraulic Report Revisions and Supplements
An approved hydraulic report may need to be revised because of design changes during the design phase or construction phase
Hydraulic Report Submittal and Archiving
Hydraulic reports shall be submitted to the following offices. 1-3.3.1 Review Copies PEOs shall submit a complete searchable electronic copy

The hydraulic report is intended to serve as a complete documented record containing the engineering justification for all drainage and
USGS Regression Equations
While measured flows provide the best data for design purposes, it is not practical to gage all rivers and streams
The Rational Method
General The rational method is used to predict peak flows for small drainage areas which can be either natural or
