Service basis

What this service supports

Client need
Runoff, drainage, detention, and flood questions affecting a project footprint or downstream receptors.
Good fit when
  • A site needs catchment, drainage-path, runoff, detention, or flood context before detailed design.
  • Existing drainage concepts or records need to be checked against terrain and available rainfall information.
  • Assumptions, data gaps, and follow-up studies need to be made explicit for project review.
What you gain
  • A structured understanding of catchments, flow paths, drainage constraints, and adopted assumptions.
  • Clearer inputs and confirmation needs for drainage planning, flood review, or detailed hydraulic work.
What information should you prepare?
  • Project boundaries, proposed grading or drainage concepts, and the decision or design stage.
  • Topography, drainage records, rainfall or flow data, observed flooding, and downstream constraints.
  • Applicable design criteria supplied or adopted by the project team.
How does HydroGeo approach the work?
Catchment review, rainfall-data handling, drainage assessment, and terrain-informed runoff context.
What can the service deliver?
Planning inputs, assumptions, limitations, and priority actions for detailed design or review.
What are the professional limitations?
Outputs depend on the adopted design criteria, available records, and site verification.
