Drainage Studies

Drainage studies are needed for the design of highway and railroad structures, for housing developments, and for construction projects in floodplains. Bridge & Stream drainage studies typically include a hydrologic analysis to estimate the design peak flow rates and a hydraulic analysis of the project site or the floodplain, with a comparison between the existing and proposed conditions. Study results may include floodplain elevations and boundaries, identification of proposed drainage structures, scour protection recommendations, and permitting requirements. Structural recommendations are generally based on constructability, cost, and environmental considerations.
