TUFLOW Description:
TUFLOW is a 1D/2D flood and tidal model that has a wide range of applications with similar capabilities to other, more expensive flood models. When compared with leading flood simulation models, TUFLOW boasts improved data handling and faster computations.

TUFLOW offers stable, robust and efficient hydrodynamic modeling at a fraction of the cost of other high-end models.

What makes TUFLOW Unique?

TUFLOW is specifically beneficial where the hydrodynamic behavior in coastal waters, estuaries, rivers, floodplains and urban drainage environments have complex 2D flow patterns that would be awkward to represent using traditional 1D network models. It is suited to modelling flooding in major rivers through to complex overland and piped urban flows, along with estuarine and coastal hydraulics.

A powerful feature of TUFLOW is its 2D/1D dynamic linking, first pioneered in 1990, and subsequently enhanced to the point where it offers unparalleled flexibility and robustness. TUFLOW continues to develop and evolve to meet the challenges of hydrodynamic modelling.
