Hydraulic Engineering Services

At Omni Civil Engineering Solutions, our Hydraulic Engineering services are designed to protect life, property, and infrastructure by managing how water moves across, through, and around a site. Whether it’s designing culverts under roadways, modeling stormwater runoff, or safeguarding developments from flash flooding, our firm provides technically sound, environmentally responsible, and regulation compliant solutions.

We specialize in evaluating both natural and man-made water systems to ensure your project is not only functional but resilient. By analyzing site topography, rainfall patterns, drainage flow, and soil characteristics, we develop intelligent water management strategies that mitigate risk and comply with FEMA, local drainage districts, and environmental permitting standards.

Most importantly, our hydraulic designs are focused on safeguarding against unexpected hydraulic circumstances such as flooding, wash-out, and erosion which can lead to costly damage, safety issues, and construction delays. We integrate cutting-edge hydraulic modeling with practical engineering expertise to ensure your site withstands real world storm events and long-term environmental exposure.

Our Hydraulic Engineering Services Include:

Stormwater Management & Flood Control

  • Hydrologic and hydraulic modeling (HEC-HMS, HEC-RAS, SWMM, etc.)

  • Design of detention and retention basins to control runoff

  • Sizing and placement of culverts, swales, and storm sewers

  • FEMA floodplain analysis, Letters of Map Change (LOMC), and elevation certifications

  • 2D overland flow modeling for large or complex drainage areas

  • Compliance with local and regional stormwater ordinances

Drainage Infrastructure Design

  • Site-wide stormwater conveyance systems (storm drain pipes, inlets, outfalls)

  • Surface and subsurface drainage layout for roads, buildings, and open spaces

  • Grading plans that promote positive drainage and eliminate ponding

  • Catch basin and trench drain design

  • Underground stormwater detention/retention systems (vaults, chambers)

Flood Resilience & Emergency Protection

  • Flash flood mitigation strategies for low-lying or high-risk areas

  • Overflow routing plans for high-volume rain events

  • Design of backflow prevention systems and emergency overflows

  • Protection of utility infrastructure from water-related damage

  • Floodproofing site features and building entry points

Erosion Control & Environmental Protection

  • Bank stabilization design for creeks, rivers, and man-made channels

  • Riprap sizing, gabion walls, and vegetative erosion control solutions

  • Slope drainage, energy dissipation, and scouring prevention at outfalls

  • Sediment control measures (e.g., silt fences, sediment basins) for construction sites

  • Long-term site stabilization planning post-development

Compliance, Permitting & Reporting

  • Preparation of drainage reports and hydraulic analyses for permitting

  • Coordination with city, county, and state drainage authorities

  • SWPPP (Stormwater Pollution Prevention Plan) preparation and erosion control notes

  • Floodplain development permitting and mitigation design

At Omni Civil Engineering Solutions, we know that water is one of the most powerful forces on a site. That’s why we don’t just design systems that move water we engineer long-term solutions that protect your property from flooding, wash-out, and erosion, while promoting environmental responsibility and regulatory compliance. When it comes to hydraulic performance, we make sure your project stays high and dry even in the most challenging conditions.
