  1. Hello Probably a fairly simple question but has been driving me round the bend. I am trying to convert a short 1D reach from ISIS to ESTRY and use the XS Database command to bring cross-section data in from the existing ISIS file. I have specified the ISIS.DAT file using the XS Database comment and produced a short 1D_NWK file (S Channel), the properties of which I would like to be taken from the specified ISIS .DAT file. What I am unclear on is how to specify the ISIS section to use at the upstream and downstream end of the network channel. Previously I have used the 1d_TAB file to point at ZX csv files. Any help gratefully received!

  3. Hello I have some (csv) inflow data which I need to add to TuFlow as point QT inflows. The time data is in a data/time format (e.g. 25/02/2010,07:30:00) rather than in hours. Can TuFlow cope with this format of time or is there an easy way to convert it to a more standard hrs only format? I could convert manually but there is a lot of data and it's not all easy to adjust. Thanks Adam

    negative QT

    I have been given output from a drainage model with flows at a number of surcharged manholes which I want to add into a 2D TuFlow model. I have configured the data as 2D_QT boundaries and linked to the model. Several of the manholes start with negative flow (very minor) which causes model instability, is there an easy way to get TuFlow to ignore -'ve QT flows? I'd rather not manually remove the -'ve values as there are a lot of manholes! Thanks
  5. ISIS Mapper (part of ISIS) can view TuFlow results without re-processing and can also generate TuFlow GIS layers. ISIS can be downloaded from www.isisuser.com, though there is a results file size limit if an ISIS "professional" licence isn't held.
  6. Not sure if this is a TuFlow bug or just a user error. I have a large number of TuFlow results for which the Max/Min results option was not enabled, I used the "Dat to Dat" utility to extract maximum V, H, D and ZUK0 results for each (faster than re-running) and then used the "TuFlow to GIS" utility to generate ASC (V,H,D and ZUKO) and MID/MIF (V only) data. All of the ASC output was fine but the MID/MIF velocity data wouldn't import into MapInfo (10) bouncing back with an "unsupported data type for column(s) v" error. After a bit of digging I noticed that the data type row in the MIF file was "v(maxmax) Float" rather than "v Float" as appeared in results which hadn't had the "dat to dat" utility run over them. Manually removing the (maxmax) text from the MIF allowed MapInfo to import the MID/MIF file as normal. Basically I'm trying to work out if the above is a "feature"/bug of the "Dat to Dat" tool or (more likely) if I messed up somewhere. Cheers Adam
  7. I am having trouble using the Tuflow_to_GIS utility to convert a TuFlow velocity DAT file into a MIF file for use in MapInfo. The command line I am using is: "C:\programs\TuFlow\Utilities\TUFLOW_to_GIS.exe -mif –vector -t99999 -sf1.0 S200_L4_05_V.dat pause" When I run the above batch file, a MIF file is created (sample below), however once read into MapInfo (I am using v8.5) only points with magnitude data are created with no vector information. If anyone has any words of wisdom/possible solutions then they would be very very welcome. Thanks Adam Sample MIF output.
