## Is Tuflow software free?

TUFLOW has a wide range of licencing flexibility to suit everyone from students to global corporations. Free or demo mode that allows users to self-train, create and commercially apply small models with full access to our acclaimed support services at no cost.

**Who made Tuflow?**

TUFLOW originated from a joint R&D project between WBM Pty Ltd and The University of Queensland in 1989/90 to develop a 2D modelling system with dynamic links to a 1D system, and has since gone from strength to strength as an industry leader.

**What is Tuflow HPC?**

TUFLOW HPC is an explicit solver for the full 2D Shallow Water Equations (SWE), including a sub-grid scale eddy viscosity model. The scheme is both volume and momentum conserving, is 2nd order in space and 4th order in time, with adaptive or fixed timestepping. It is unconditionally stable.

### What is flood Modelling?

Conceptually, flood modelling generally involves developing algorithms useful to characterise flooding in terms of flood water depth and extent as well as flow velocity [17].

**What is Hydraulic Modelling?**

A hydraulic model is a collection of mathematical equations that give a simple representation of reality. They estimate: flow, water level and velocity in river channels. pipe networks.

**Why is flood modeling important?**

It is the key factor to reduce or prevent the level of flood hazards that ensuring prediction accurately of the flood inundation area and providing reliable information of risk. In general, the result produced by flood models is only a single deterministic prediction for the peak flow of the flood.

## What is the difference between 1D and 2D flood Modelling?

In 1D models, topography is defined by cross sections which generate a precise definition of river bed but a rude definition of the floodplain [19]. In 2D models, the mesh provides information about the river topography. This kind of information is used to define very precisely the topography of the floodplain [12].

**Why is hydraulic modelling important?**

Hydraulic models enable a variety of ‘what if’ scenarios to be explored and, as such, are proving to be important tools for water companies and local authorities in order to develop solutions and strategies to deal with current or future drainage issues, as well as helping developers prove that flood mitigation will be …

**How does a flood model work?**

2D flood modeling interprets the 2D equations of flow to find out the water depth and depth-averaged velocity on a grid or mesh. It uses digital terrain modeling and bathymetry of a water channel in the question to outline the 2D-flow of an expected flood.

### What is 1D hydraulic model?

1D and 2D hydraulic models are used to assess the full impact of flooding on a development, as well as the development’s impact on a local watercourse. They can be used separately, or together in a combined 1D/2D model, depending on the complexity of the site and what information is needed.

**When would you use 2D modeling?**

2D models should be used when flow patterns are complex and 1D model assumptions are significantly violated. 2D models generally provide more accurate representations of flow distribution, velocity distribution, water surface elevation, backwater, velocity magnitude, velocity direction, flow depth, and shear stress.

**What is the TUFLOW licence free tutorial model?**

This TUFLOW licence free tutorial model is aimed at new users, stepping through the process of building and running a model. TUFLOW doesn’t have its own graphical user interface (GUI), it uses GIS software and text editor for its model creation and result viewing.

## What is a TUFLOW file?

A small, free form text file that controls the data flow and non-GIS parameters for a TUFLOW simulation. This is at the top of the tree for controlling a TUFLOW simulation. This is essential for every TUFLOW simulation. Can be colour coded in advanced text editors such as UltraEdit or TextPad.

**How many TUFLOW models are there in the database?**

Example Models This database includes over 60 example models demonstrating the most commonly used TUFLOW features. Use these models to learn how to implement features not included in the TUFLOW eLearning or Wiki Tutorials.

**Where can water flow in a TUFLOW model?**

By default, every grid cell in a TUFLOW model will set as active, thus TUFLOW will allow water to flow anywhere within the extents of the 2D domain. It is rare for a catchment to be a perfect rectangle!
