Robert Fortuin is Director, Founder and Technical Lead at Delta Hydro Engineers (Pty) Ltd, where he leads engineering-grade flood risk intelligence and modelling work: high-resolution hydrology and hydraulic simulation (1D and 2D), floodplain and floodline analysis, dam breach studies, and stormwater-related hydraulic assessments—often with GIS-integrated, repeatable workflows so outputs stay traceable for review and design teams.
He founded the practice in May 2025 to translate complex flooding scenarios into decision-ready metrics for infrastructure, mining, and development clients, complementing coarse global datasets with locally calibrated models where it matters for approvals and risk decisions.
Alongside Delta Hydro, Robert has worked since December 2013 as a Senior Water Resources Engineer at OFC Consulting, supporting public- and private-sector projects across South Africa. A large share of that work sits in surface water management and Water Use Licence Application (WULA) pathways with the Department of Water and Sanitation (DWS)—including rainfall analysis, stochastic rainfall datasets, design hyetographs, hydrological modelling, and 1D/2D hydraulic modelling to support defensible floodlines and surface water solutions.
Since January 2015 he has delivered PCSWMM training in South Africa on behalf of Computational Hydraulics Inc. (CHI), covering practical hydrological and hydraulic modelling workflows, stormwater system performance, and flood simulations using GIS-integrated datasets.
Robert is listed as the Information Officer for POPIA enquiries relating to this website.
