Selection depends on terrain, solver needs, and client preferences—we justify the choice.

Can you model bridges inline?

Yes—including piers, scour-sensitive reaches, and afflux constraints.

Do you provide mesh independence studies for 2D?

Where required by the brief, we document sensitivity to mesh resolution.

2D modelling timelines?

Larger 2D domains take longer—schedule depends on extent and data quality.

Do you provide animations for stakeholders?

Where helpful, we can export visualisations—scoped to the review purpose and data limitations.

How we help in Cape Town

Model selection depends on terrain, structure controls, and the questions the study must answer. In Cape Town, Winter frontal rainfall and steep mountain catchments drive sharp runoff peaks; coastal storm surge can compound flood risk in low-lying corridors. Our team supports projects across Western Cape with studies scoped for municipal and DWS review cycles.

Cape Town sits within Western Cape, where City of Cape Town stormwater and environmental by-laws shape approvals for new development and infrastructure upgrades. For this service, we emphasise defensible hydrology, clear assumptions, and deliverables that integrate with your professional team—survey, civils, and environmental practitioners—so approvals move without rework.

When do you need this?

Flood inundation mapping for planning and safety cases
Bridge and culvert hydraulic performance and afflux
Dam break and downstream routing studies
