SMS:TUFLOW Numeric Engine

TUFLOW is a computational engine that provides two-dimensional (2D) and one-dimensional (1D) solutions of the free-surface flow equations to simulate flood and tidal wave propagation. The engine is very stable making it an excellent choice for models with lots of wetting and drying. It is specifically beneficial where the hydrodynamic behaviour 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.

A powerful feature of TUFLOW is its 2D/1D dynamic linking, first pioneered in1990, 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 modeling. Its strengths include:

• rapid and stable wetting and drying;
• 1D and 2D linking;
• multiple 2D domains (optional);
• both 1D and 2D representation of hydraulic structures;
• automatic upstream/downstream controlled flow regime switching;
• 1D and 2D supercritical flow;
• highly flexible and efficient data handling;
• GIS based; and
• extensive quality control outputs.

It is suited to modeling flooding in major rivers through to complex overland and piped urban flows, along with estuarine and coastal hydraulics. [1]
