The course includes TUFLOW theory, followed by practical model creation and review of results. 2019 Release Workshop Aimed at all TUFLOW users from modellers to managers. The day will provide detail and discussion of the new features included in the 2019 release. 2019 Release Training Computer-based training is tailored towards existing modellers who want to learn, and have a hands-on experience, using the 2019 release features. People attending this session are advised to also register for the release workshop the day before. We look forward to seeing you there! Kind regards, The TUFLOW team
  3. Hi David, Unfortunately it's not possible to use a blockage matrix for any pit type yet. This is something on the dev list but not yet in TUFLOW. The work around at the moment would be to create separate GIS pit layers for each blockage scenario with different blockage values and read these into your ECF using IF SCENARIO logic and/or Variables. Example USING SCENARIO LOGIC In your ECF IF Scenario == 50p Read GIS Network == gis\1d_nwk_pits_50p_001.shp Else IF Scenario == 20p Read GIS Network == gis\1d_nwk_pits_20p_001.shp Else Read GIS Network == gis\1d_nwk_pits_00p_001.shp End IF OR USING VARIABLES and SCENARIO LOGIC The advantage of this method is that you can put a lot of your logic in a separate file and keep your control files cleaner. Define your variables in a TUFLOW Read File (.trd) IF Scenario == 50p Set Variable BLOCKAGE == 50p Else IF Scenario == 20p Set Variable BLOCKAGE == 20p Else Set Variable BLOCKAGE == 00p End IF In your TCF read the .trd file Read File == Variables.trd In your ECF read in your pits layer using the variable Read GIS Network == gis\1d_nwk_pits_<<BLOCKAGE>>_001.shp Thanks, Ellis
  4. Hi TUFLOW Users, We’re happy to announce that registration for the 2019 Australian and New Zealand TUFLOW Training is now open. This year we are offering more training courses that cover a wide range of topics. These are great sessions for all levels of experience; for new users looking to get a hands-on experience building 2D models, and for existing users looking to enhance existing knowledge and learning the latest tips and tricks. Please visit https://www.tuflow.com/Training.aspx for more information on the training. The first training is not too far off and spots are filling fast so don't miss the chance to learn TUFLOW directly from the software developers. We look forward to seeing you there, Ellis Symons
  5. Hi Hai, Thanks for bringing this to our attention. The bug should now be fixed for QGIS 2 and the new plugin version retrievable from the repository. Thanks, Ellis

  9. Hi Jacky, answer to your questions below: 1. No it shouldn't matter as long as you are snapped to a vertices 2. TUFLOW does not take into consideration bends when modelling open channels in 1D. By definition, 1D solvers do not understand bends as it assumes water is always flowing downstream perpendicular to the cross section. If you have any tight bends in a 1D channel, you may want to consider manually adding additional energy loss to account for these features. A reason why you would want to follow the gully when digitising your 1d_nwk layer is a) your asking TUFLOW to automatically calculate the length of the channel b ) it's good practice from a QA side for model 'readability' i.e. someone looking at the model for the first time will get a better immediate understanding of what's being modelled. A series of cross sections with straight channels in-between may look to an outsider like your realigning the creek. One of the powerful features of TUFLOW is that it is built in a GIS environment where everything is spatially referenced. This allows for model layers to be drawn intuitively with respect to features such as the terrain and aerial imagery. 3. The 1d_xs.shp file is simply a reference to the CSV file, and is used by TUFLOW to determine which 1d_nwk channels use which cross section CSV files. Details such as vertices and line length do not need to align. 3a) see above 4. As per Table 7-5 in the TUFLOW Manual the datatype ZP used for the point file used in the command Read GIS Z HX Line Max == will adjust the cell elevation. This is the same as having a thick line. So Yes, it is automatically assumed THICK (THIN Z lines will adjust cell sides, not cell elevations) 5.Yes and No. Water levels are calculated at the start and end of 1d_nwk channels (this is at 1d_nwk nodes as TUFLOW will automatically insert a node at these locations if there isn't one already). The CN line is a connector that tells TUFLOW where this 1D node level connects with the 2D. Water level is interpolated along the HX line to the next time it's connected to a 1D node via a CN line. If the vertices are really close together then it may not matter which one the CN line is connected to. However, if you choose a location too far downstream or upstream from the 1D node to snap to, then you may get a discrepancy between 1D water levels and 2D water levels. Cross sections have no bearing on this connection. Thanks, Ellis

  11. Hi Jesse, The TUFLOW Wiki has some good information on methods to run, queue, and schedule TUFLOW runs. https://wiki.tuflow.com/index.php?title=Running_TUFLOW Are you asking after a specific scheduling environment software? Thanks, Ellis
  12. Hi Tom, This looks like this could be a Fortran error and it not being able detecting the end of a file. Unfortunately this error can happen and seems to occur at random (more so for certain Fortran compilers, and i'm not sure how the 2013 release of TUFLOW was compiled). This was indeed fixed in the 2017-09-AB release. If you need to use the 2013 build and this keeps occurring, then you could try the following : Initialise the model in the latest TUFLOW build, this will generate XF files for the zpts.mid (for more information on XF files see Section 4.10 of the 2016 TUFLOW manual) For the 2013 model build runs, read in the XF files directly (see example below) instead of the .mid file. Read MID Zpts == mi\xf\2d_zpt_001.mid.xf8 Thanks, Ellis
  13. Hi Josh, You're right, the Profile from Line plugin doesn't appear to be available anymore. As far as i know, the Profile Tool is the best option for producing cross sections, however as you probably are aware, is not so good for doing this en mass. If you have access to ArcGIS (using Stack Profile) or 12d (using Drape) these would probably be slightly more automated techniques. Thanks, Ellis
  14. Hi Josh, Have you tried outputting to .asc or .flt grids? Using grid results instead of the .xmdf results should remove the zero values in the profile tool. You can output to grid straight from TUFLOW (Output Format == FLT or ASC), or use the TUFLOW_to_GIS.exe utility to output to grid from the .xmdf results (https://wiki.tuflow.com/index.php?title=TUFLOW_to_GIS). Thanks, Ellis
  15. Hi, We have a large example model database (links below) with example models covering the requested items. Tutorial module 8 is also available and has those items combined in one model.
