Hi all, I am running a direct rainfall model and I am trying to use PO lines to obtain hydrograph outputs at key locations in my model. When I first tried to use PO lines in my tcf it came up with the error 0046 - Time Series Output Interval not specified. I was able to fix this error by using the command Time Series Output Interval == 3600. The model runs, but without any rainfall entering the model. When I remove the PO lines but keep the Time Series Output Interval command the model still runs without rainfall. The model was running with rainfall before and when I remove the Time Series command. Also, the model I have that uses 2d_bc input hydrographs rather than 2d_rf layers seems to run fine with the PO and Time Series commands. I have attached my tcf.

Hi All, I am a engineering student doing some flood modelling for the West Gippsland CMA and I am experimenting with TUFLOW's Direct Rainfall modelling to see how viable it can be for rural catchment simulation.The issue is that in order to keep this flood study in line with the 2016 ARR I have to stochastically vary my rainfall data, meaning that I have to run a large suite simulation (roughly 70) that varies the rainfall data read by the 2d_rf layers. What I need help with is that I am struggling to find an efficient way to view and analyse the large set of data produced by this suite of simulations. I am trying to compare the results between each individual run to find which storm duration/temporal pattern combination generates the largest flood extent, depth of flood water, water velocity, etc. I am just wondering if anyone had any tips or tricks that they were happy to share with me. Thanks, Rhain
Dear TUFLOW Users, Tutorial Model 8 - Direct Rainfall is now online and available for download. This module includes examples on the powerful depth-varying roughness feature in TUFLOW, hyetograph input methods, mass conservation considerations and also the differing approaches required when presenting and reviewing rainfall on grid results. Tutorial Model 8 forms part of a larger series of free tutorial models that users can download and run without a TUFLOW license. They are great for beginners or even those looking to use the latest modelling techniques. Follow these links to get started on the tutorial: http://wiki.tuflow.com/index.php?title=Tutorial_Module08 (Tutorial Wiki) http://www.tuflow.com/Tuflow%20Tutorial%20Models.aspx (Model and Data) Should you have any further queries please don't hesitate to send us an email at email@example.com.

Hi all, Do you have advice for presenting results for a Rainfall on Grid model within SMS? I've been using this procedure for the usual QT inflow hydrograph-only models, with pretty good results: http://wiki.tuflow.com/index.php?title=SMS_3D_Animation However, with Rainfall on Grid, there are wet cells everywhere, so the depth contouring shows water everywhere (see screenshot below). Ideally, there would be some way I can set the cut-off for the depth (d) layer to be higher than say 100-200 mm. However, the Functional Surface in use is the level (h) layer so I can't seem to set limits on the depth (d) Contour Surface. Cheers, Danny
