Hydrology and Flood Hydraulics
A fundamental and rigorous understanding of how water behaves is central to managing catchments, floodplains, drainage networks, rivers, estuaries and coastal lakes. Such understanding requires skills and knowledge to address the volumes and rates at which water discharges from a catchment (i.e. the hydrology), and also a commensurate capacity to understand how these waters move through and across the drainage system or floodplain (i.e. the hydraulics).
We have an extensive team of specialist engineers and scientists who work full-time on hydrologic and hydraulic studies, ranging from small urban catchments to major floodplains conveying flows in excess of tens of thousands of cubic metres per second. We are also very experienced with coastal lakes and estuaries, where flooding results from a combination of coastal and catchment processes.
We offer the following specialist hydrologic and flood hydraulic management skills:
- Flood frequency analysis for peak and low flows
- Rainfall-runoff modeling including calibration, for design flood estimation
- 1D and 2D floodplain modelling using both proprietary and in house software (Tuflow)
- Coastal lake flooding and dynamic entrance breakout analysis
- Extreme flood estimation, including Probable Maximum Floods
- Dambreak analysis
- Real time flood forecasting and warning
- Open channel hydraulics including unsteady flow and two dimensional modelling and bridge hydraulics
- Urban stormwater pipe network and retardation basin design and analysis.
