  1. Dear TUFLOW users, We have started a crowd-funding campaign to refactor and port Crayfish to QGIS 3. The current Crayfish will not work in the upcoming QGIS. In addition, we'd like to add support for 3D canvas and loading large files. http://www.lutraconsulting.co.uk/crowdfunding/qgis-crayfish-3/ We will prioritise support of the formats for users who contribute to the crowd-funding. Regards, Lutra Consulting
  2. All If I wanted to model a large river channel and floodplain using 2D only, how would people go about including the river channel bathymetry into the DTM? LiDAR will provide the terrain data, but will poorly-define the river channel itself. Is there a way to use channel cross section data to modify the base DTM to reflect the surveyed channel? We have regular channel cross-sections, and would like to use this data to 'carve' a more detailed channel through the DTM. The method will need to account for any meanders etc... Are there clever ways to do this in Arc/MapInfo/QGIS? Any pointers gratefully received :-)
  3. Lutra Consulting are very happy to announce the first stable release of the Crayfish Plugin for QGIS. Crayfish allows hydraulic modelling results from packages like TUFLOW to be viewed natively in QGIS without having to first convert them to intermediate GIS formats. The tool supports both contour and vector datasets and allows users to quickly flick between output steps to gain a full appreciation of the hydraulic mechanisms at work within their model. Please see the project page on our website for full details of how to install and use.
  4. We are very excited to announce the release of Crayfish 1.1.1 which now supports TUFLOW FV results, projection-on-the-fly, long-section profiles and transparency. Also many previous issues fixed. See here for full details of this release. Installation instructions can be found on the main project page.
