Stephan Dreyer leads hydraulic modelling and infrastructure-focused flood work at Delta Hydro Engineers, including 1D/2D river and stormwater modelling, dam safety hydraulic inputs, and stormwater management plans for South African municipal review.
He supports project teams where conveyance capacity, tailwater and backwater effects, erosion risk, and consequence mapping directly influence design decisions. Typical work includes model build and QA, structure performance assessment (culverts/bridges/outfalls), exceedance routing and major-system checks, and translating modelling outputs into buildable drawings and maintainable asset strategies.
He supports clients in mining, transport, property, and public-sector programmes where conveyance capacity, erosion, and consequence mapping are central to design decisions.
