Hydraulics + Hydrology
Demands placed on highway systems can cause or exacerbate flooding issues. Whether your project is a new highway on new alignment or improvements to existing roadways, HR Green’s professionals have extensive experience addressing the conveyance of stormwater.
We perform coordination and detailed hydrologic and hydraulic modeling to improve geometrics of intersections, analyze impervious areas and alleviate existing drainage problems. We also analyze highway culverts, complete stream and structure surveys, engineer stream crossings and develop detailed plans for drainage alternative analysis.
Our highway drainage services include location drainage studies, bridge and culvert hydraulics and design, scour analysis and unique stormwater collection and conveyance systems.
