Advanced 1D and 2D hydraulic simulations predicting flood depth, velocity and flow paths — the technical backbone underpinning every credible flood risk study, dam safety assessment, and drainage design.
Hydraulic modelling is the technical engine behind every flood risk assessment. It takes hydrological outputs — peak discharges, flood hydrographs — and converts them into spatial predictions of where water will go, how deep it will be, how fast it will flow, and how long the flooding will last.
HYDRisk hydraulic models are built from site-specific geometric data — not generic DEM datasets applied without verification. Every model is calibrated against available observed flood data, and validated against independent sources before results are accepted.
The choice of modelling approach — 1D steady-state, 1D unsteady, 2D dynamic, or coupled 1D-2D — is made on a project-by-project basis based on the hydraulic complexity of the site, the precision required, and the regulatory framework being satisfied. We do not apply a standard approach regardless of context.
Outputs are delivered as GIS-format flood hazard maps in GeoTIFF and Shapefile — directly usable in planning portals, design software and client GIS systems — alongside a structured technical report.
Understanding what this study delivers — and what happens without it — is the fastest way to evaluate whether your project needs it.
Every HYDRisk study produces a defined set of technical outputs — here is exactly what you receive.
Every tool we use is the same software trusted by government agencies, major engineering firms and regulatory bodies worldwide.
Methodology, data sources and regulatory requirements differ between geographies. HYDRisk delivers the right approach for every region.
