2D & 1D Hydrodynamic Flood and Tide Simulation
TUFLOW is a finite difference 2D and 1D flood and tide simulation software. It simulates the hydrodynamics of water bodies using 2D and 1D free-surface flow equations. TUFLOW is developed for determining flow patterns in coastal waters, estuaries, rivers and floodplains where the flow patterns are essentially 2D in nature and cannot or would be awkward to represent using a 1D network model.
Its strengths include excellent model stability and convergence, rapid wetting and drying, powerful 1D and 2D linking options, multiple 2D domains, 1D and 2D representation of hydraulic structures, automatic flow regime switching over levees and embankments, 1D and 2D supercritical flow, effective data handling and quality control outputs. It is suited to modelling flooding in major rivers through to complex overland and piped urban flows, and estuarine and coastal hydraulics. TUFLOW uses GIS to manage, manipulate and present data, and third-party software such as SMS to view and animate results.
