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 East London

Hydraulic modelling translates flows into depths, velocities, and inundation patterns using 1D/2D tools such as HEC-RAS and MIKE. In East London, Coastal hills and Buffalo River tributaries concentrate flows; summer rainfall can produce rapid rises in smaller catchments. Our team supports projects across Eastern Cape with studies scoped for municipal and DWS review cycles.

East London sits within Eastern Cape, where Buffalo City stormwater and planning processes shape flood studies for harbour-linked industry and coastal development. 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
