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 Johannesburg

Model selection depends on terrain, structure controls, and the questions the study must answer. In Johannesburg, High-intensity convective storms over urbanised catchments increase peak flows; legacy mining infrastructure and dolomitic areas add complexity. Our team supports projects across Gauteng with studies scoped for municipal and DWS review cycles.

Johannesburg sits within Gauteng, where Johannesburg and Ekurhuleni municipal stormwater frameworks influence floodline and stormwater submissions for greenfield and infill projects. 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

Methodology, deliverables, standards, and FAQs are maintained on the national service page—updated as regulations and municipal guidance evolve.
