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 George

Model selection depends on terrain, structure controls, and the questions the study must answer. In George & Garden Route, Mountain catchments deliver rapid runoff; coastal lakes and estuaries are sensitive to altered flows and flood levels from upstream development. Our team supports projects across Western Cape with studies scoped for municipal and DWS review cycles.

George & Garden Route sits within Western Cape, where George, Knysna, and Bitou planning contexts each influence stormwater and environmental approvals along the coastal strip. 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
