Design Flood Estimation — multi-method catchment studies

Map-led catchment studies: delineate a catchment, run multiple flood estimation methods, and export design-grade Word, Excel, and GIS outputs.

What is Design Flood Estimation?

Map-led catchment studies: delineate a catchment, run multiple flood estimation methods, and export design-grade Word, Excel, and GIS outputs.

When would you use this?

  • You need a single catchment study with several methods for comparison.
  • South African submissions where regional methods and rational/SCS variants matter.

How Delta Hydro Studio handles it

  • Multiple industry methods in one project workspace.
  • Automated delineation and parameter assistance where datasets allow.
  • Client-ready exports instead of pasted spreadsheet screenshots.

How to use it

  1. 1

    Drop a pin or upload your catchment boundary.

  2. 2

    Select methods and return periods for the study.

  3. 3

    Review intermediate results and QA flags in the workspace.

  4. 4

    Generate the report pack and GIS/CAD exports.

Methodology & references

Full equations, assumptions, and literature references appear inside the in-app methodology panels for this tool, aligned with South African guidance (SANRAL TRH, SANCOLD, DWS technical manuals) and international references (USDA NRCS, FHWA HDS) where applicable.

Outputs & exports

Export professional Word and Excel report packs, tabulated results, and GIS-friendly layers depending on the tool. Screenshots in marketing materials are refreshed as the UI evolves — the studio always reflects the latest layout.

FAQ

Do I need a desktop GIS install to use Design Flood Estimation? +
No. Delta Hydro Studio runs in the browser — upload inputs, run calculations, and export professional outputs without local GIS installs for most workflows.
Is there a free tier? +
You can start free on the Stream plan with credits to explore tools. Several hydraulic and delineation tools remain accessible without a paid subscription.
Where are my data and calculations stored? +
Projects live in your Delta Hydro Studio workspace. Export Word, Excel, and GIS formats when you need offline archives or submittals.
