TUFLOW has a wide range of features, developed and incorporated based on the feedback from modellers and clients. Key features include:
|
Layered data approach:
- No need to duplicate input data layers.
- Easy manipulation of layers
- No limit on the number of layers.
|
|
GIS layers independent of cell size, location and orientation:
- Very easy to change 2D cell size, or reshape your model, without having to change your input data.
- Start modelling on a coarse 2D grid, then switch to a finer grid once the model is established.
|
|
Easy modification of 2D topography, roughness and other inputs:
- Thin (cell sides only), whole cell and wide breaklines for easily representing fences, levees, embankments, diversion channels.
- Not one, but five (5) ground elevations per cell are used computationally. 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:
- 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:
- Powerful and proven 1D network modelling solution that’s been in use and continually enhanced for over 40 years.
- Open channels, bridges, weirs, culverts, gullly traps, manholes, pipes, and so on.
- Update or override 1D elements using separate layers – no need to duplicate unchanged data when modelling different scenarios.
- Tools to automatically generate 1D cross-sections from DEMs and TINs and interrogate roughness values across the cross-sections from your land-use mapping.
- Import extensive GIS pipe network and manhole layers.
- Pipe networks handle surcharging and 12 different pipe flow regimes.
- 1D timestep is different to the 2D timestep and does not force a reduction in the 2D timestep
- 1D links to a 2D domain do not need to be reworked if the 2D cell size changes.
- Custom pit inlet or gully trap curves.
- 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:
- Stable 1D structures that don’t rely on artificial energy losses for stability.
- Modification of 2D cells to model bridge piers, decks, fine-scale energy losses, side wall friction of box culverts.
- Vary parameters in the vertical to model bridges and horizontal blockages such as pipelines in 2D.
|
|
Automatic flow switching in 1D and 2D:
- Automatically switches between upstream controlled (supercritical and weir) flows and downstream controlled (subcritical) flows in both 1D and 2D solutions
|
|
1D/2D Linking:
- Robust, stable and powerful 1D/2D linking without any need to change your 2D timestep.
- Easily carve a 1D open channel through a 2D domain simply by digitising 1D-2D interface lines.
- 1D/2D channel/floodplain linking applies full equations (only uses weir equation if upstream controlled). Spill levels based on 2D topography (not 1D cross-sections) thereby breakouts between cross-sections are correctly modelled.
- 2D scheme dynamically linked with ISIS and XP-SWMM.
- 1D scheme dynamically linked with ISIS.
|
|
Fast:
- One of the fastest 1D/2D solutions available.
- For real-world models, probably the fastest, most reliable solution.
|
|
Versions:
- 32 and 64-bit versions available.
- Single and double precision.
- Regular annual releases.
- Interim updates with minor enhancements and any bug fixes.
|
|
Affordable:
- Very cost effective and excellent value for money.
- Inexpensive networking options with no limitations across countries/offices.
|
|
Powerful multiple events and scenario management:
- Can run all your simulations for a study using a single master file.
- Batch bulk simulations and assign different levels of priority and CPUs.
|
|
Extensive quality control (check) outputs:
- Optionally output a multitude of GIS layers to proof and review your model.
- Running commentary of all input data displayed and logged so you can see what the software is doing.
- Detailed mass balance reporting on screen and to _MB.csv files.
- Display and reporting of healthy model indicators so you know whether there are issues that might need attention.
- Messages are displayed geographically so you can see where the problem is.
|
|
Numerous “little” features that make life easy such as:
- Packaging up a copy of your model for extra backup or delivery to others.
|
|
Advanced flood risk management analyses:
- Evacuation route monitoring and outputs.
- Flood gauge output time and level information appended to GIS property databases.
- Automatic modification of topography based on flood hazard or other output for examining future planning options for identifying floodways and floodplain development controls.
|
|
Customise TUFLOW by creating your own TUFLOW_USER_DEFINED.dll. For example:
- Write your own hazard categories classifications.
- Implement your own infiltration routine.
- Output results in a different format.
|
|
TUFLOW Support:
- Active, focussed, TUFLOW Forum where over 600 registered members contribute their problems, solutions and ideas.
- support@tuflow.com where you get advice from the developers who don’t just write software, but have years of hands-on modelling experience.
- Messages and useful tips Wiki for learning how to solve an error, warning or check message a modeller may encounter.
|
|
TUFLOW Training
- Customised or bespoke training for project based models.
- Larger group generic training.
- Training by those who develop and extensively use TUFLOW on projects.
|
|
TUFLOW Tutorial Model
- Excellent for self teaching or in-house training of new staff.
- TUFLOW licence not required to run the models so your trainees don’t use up your TUFLOW licences.
- Model can be modified so that you can test and play with ideas.
- 2011 version will have an additional six modules covering recent TUFLOW features and advanced modelling techniques.
|
|
Useful Free (unlicensed) Utilities including:
- Generating TUFLOW inputs (eg. xsGenerator that generates 1D cross-sections from XYZ surveys and land-use polygons to vary roughness across the section).
- Post-processing TUFLOW output such as TUFLOW_to_GIS to produce 3D flood and other surfaces, velocity arrows, longitudinal profiles, calibration plots, etc.
- Utilities for Excel for managing tabular (eg. boundary) databases.
|
