A text editor such as UltraEdit. External links can be at any orientation, start completely dry, and wet and dry during a simulation.

Its strengths include 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. When archiving, place in a folder tufflow using the Build ID, eg. Mass balance output is available for 2D domains see Mass Balance Huflow and automatically output for 1D domains.

Customised or bespoke training for project based models Larger group generic training Training by those who develop and extensively use TUFLOW on projects.

In its simplest form, the assumption is the water level along a link is horizontal. Thin cell sides onlywhole cell and wide breaklines for easily representing fences, levees, embankments, diversion channels Not one, but five 5 ground elevations per cell are used computationally. Manhole energy losses can be recalculated every timestep based on the manhole shape, expansion and contraction of flow, flow distribution between pipes, angles of approach, and pipe invert drops Hydraulic Structures in 1D and 2D: Display and reporting of healthy model indicators so you know whether there are issues that might need attention.

The flow hydrograph is distributed equally to all nodes that fall within the region except H boundary nodes. New command Conveyance Calculation offers an alternative approach to calculating channel conveyance without the risk of conveyance reducing with height. Automatically switches between upstream controlled supercritical and weir flows and downstream controlled subcritical flows in both 1D and 2D solutions.

Up until it was used extensively by WBM Pty Ltd for estuarine and coastal studies, with the occasional flood study.

Can also generate individual domains using Write MI Domain in the tgc file. Seamless linkages with GIS and third party interfaces and schemes: It is suited to modelling flooding in major rivers through to complex overland and piped urban flows, along with estuarine and coastal hydraulics.

TUFLOW is a powerful computational engine that provides one-dimensional 1D and two-dimensional 2D solutions of the free-surface flow equations to simulate flood and tidal wave propagation. Spreadsheet software such as Microsoft Excel for managing tabular data eg. The advanced linking functions developed have been extensively applied to a wide range of models varying from major river systems to fine-scale urban flood models to coastal storm tide inundation.

TUFLOW is applicable for modelling flooding in major rivers through to complex overland and piped urban flows, and estuarine and coastal hydraulics.

TUFLOW - About Us

Software Services Support Downloads About. TUFLOW is specifically orientated towards establishing 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. This may be a small culvert through an embankment or a complex underground pipe network.

It is an finite difference, alternating direction implicit ADI scheme solving the full 2D free surface shallow water flow equations. This is useful where the drain, creek or river is too coarsely represented by the 2D topographic resolution and is better represented by 1D cross-sections. Vary the cell size, orientation, extent and timestep in the one model Represent different areas of your model using different 2D resolutions Interconnect different 2D domains to one or more 1D domains or to each other 1D Network Domains: As for other links, the 2D cells along the banks of the 1D channels can wet and dry at any point during a simulation.

Use of node attributes to set channel upstream and downstream inverts.

MapInfo is used to interactively select and graph time-series results from the 1D and 2D domains. The scheme has been improved to handle upstream controlled flow regimes eg. Useful Free unlicensed Utilities including: Elevations are specified at the cell centre, and each mid-side allowing the whole cell or just the cell sides to wet and dry — great for modelling thin features such as fences or levees Easy removal or interpolation across missing or bad DEM data — simply digitise a polygon to interpolate across null areas in your DEM 3D shape layers that make it very easy to re-shape your topography for all those what-if scenarios Multiple 2D domains Module:
