I will design hydrocad stormwater detention and retention ponds
About this Gig
Need reliable stormwater runoff calculations, HydroCAD modeling, or detention pond sizing for a U.S. development project?
I provide professional HydroCAD stormwater and hydrology modeling for residential, commercial, and site development projects. I can analyze pre vs. post development runoff, size detention/retention storage, route storm events, and evaluate outlet structures based on the project data and applicable local requirements.
SERVICES INCLUDE:
- Pre- vs. post-development peak runoff analysis
- HydroCAD watershed and subcatchment modeling
- SCS/NRCS hydrology methods and hydrograph generation
- Detention/retention basin sizing and stage-storage routing
- Outlet structure analysis: orifices, weirs, risers, culverts and outlet pipes
- Peak discharge and hydrograph summaries
- Professional PDF hydrology/stormwater calculation reports
WHY CHOOSE ME?
- Clear, organized calculation reports
- Practical basin sizing and routing analysis
- Professional communication and fast turnaround
- Results prepared for engineering review and coordination

FAQ
What software do you use?
I use HydroCAD for watershed modeling, runoff hydrographs, pond routing, storage analysis, and outlet structure modeling.
What information do you need to begin?
Typically, I need the project location, site/civil plans, existing and proposed drainage areas, land-cover information, soil/Hydrologic Soil Group information, design storm requirements, and any applicable local stormwater criteria.
Can you perform pre- and post-development analysis?
Yes. I can model existing and proposed conditions and compare peak discharge and hydrograph results to evaluate runoff changes and required mitigation.
Can you model multi-stage outlet structures?
Yes. HydroCAD can model multiple outlet devices and complex outlet configurations. The specific configuration will depend on the project requirements and available design information.
Can you work from a PDF or CAD site plan?
Yes, provided the plan contains sufficient information for the requested scope. I can work with available site plans, drainage plans, CAD information, grading information, and other project documents.
