  1. Thank you for your advice Stephanie. It works now.
  2. I'm trying to view a flood extent with velocity vectors on but I'm struggling to show both parameters at the same time. I turn on Functional Surface and Vectors in Display Options and I get a grid of functional surface as shown in the attached. I've tried Contours but then I get contour lines instead of the surface contour. Without Vectors on the Functional Surface seem to show the result as extent and not grid. Does anyone know what's the right way to view surface contour and vectors at the same time? Many thanks.
  3. Totally agree with stormwater01. I personally don't use them as I always use search. But it wouldn't be a bad idea if you put them on the next page or in the table of contents or something.
  4. Hi, I'm trying to connect an ISIS channel directly to an ESTRY pipe but have received an Error XY: ERROR 1394 - No external 1D scheme node linked or snapped to Node S6cu.1 or invalid attribute value. If using a X connector check direction (end of connector snaps to external node). Conn Attribute = X1DQ Basically, at the end of ISIS channel (before connect to a culvert), I created a junction with a HT boundary connected to it. A ESTRY node with X1DQ attribute is then snapped to the ISIS node (HT boundary) and connected to an ESTRY pipe. At the other end of the pipe I do the same by connecting the pipe to an ESTRY X1DH node which is snapped to an ISIS Node (HT boundary). I've tried to connect with a x connector but still it doesn't recognise the link. Does anyone see what's wrong here? Many thanks.
  5. And also, To reinstate the zpts, two additional attributes are required to be added to the 2d_vzsh layer with the period of the breach and the breach closure. This is explained under point 26 of the 2012 release notes.
  6. Hi Stephanie, I've just sent the model files through. Many thanks.
  7. Thank you for you suggestions PHA. I've tested the vzshp file with Read GIS Z Shape to check the zpt alteration, and it seems to be doing what I expected. Only when I read it with Read GIS Variable Z Shape (with specified trigger value at time 0hr and period of 72 hours), it doesn't seem to trigger the breach. (I can see from my PO lines across the top and the bottom of the defence that the elevations are not changed and there are no flows through it. Simulation shows no flow or breach either.) My model starts running from time 0hr and the safe data check is on. Still not sure what's wrong here. Any other suggestions?
  8. I have set up a simple tidal breach model using vzshp but am unable to get a breach to start. Basically, I've defined a vzshp over a defence to start a breach (invert=2mAOD) from time 0 hr and close after 72 hours, with a HT tidal boundary applied behind the defence (tide levels are greater than 2mAOD). I've also tried it with a trigger point behind the defence at the level the breach should occur (4mAOD) but it still won't open. Does anyone see what's wrong here? (green - HT tidal boundary, blue - vzshp breach, grid size 10m) Many thanks.
  9. I am currently undertaking some overland modelling on a relative large rural catchment. The flows calculated are quite large. I have played around with initial loss = 20mm and continuing loss = 2mm/h. However, I am wondering if there is a standard based on soil types in the UK I can refer to and more accurately represent initial and continuing losses or indeed if there are any best practices I can refer to. I understand that other software (i.e. Floodflow and InfoWorks) have the Old and New UK runoff models built in but I don’t have access to these models. Your help would be much appreciated. Many thanks. Siripen
  10. Thank you for your reply, Phil. Here is the screenshot. I will try to insert additional vertices and see if it helps. Kind regards, Siripen
  11. Hi, I'm working on a 1D/2D model with an island (between two channels) represented in the 1D element as extended floodplain. I would like to output the 1D water level on my 2D result. However, the 1d_WLL doesn't seem to produce the correct elevation on the island. As you can see on the screenshot, I tried to draw the WLL from the main channel across onto the floodplain but this doesn't seem to produce the right ground elevation. Any suggestions would be much appreciated. Many thanks. Siripen
  12. Hi PHA, Thank you for your advice. Your schematisation seems to work well and the transition is smoother. Mathieu, I've got a screenshot of the new schematisation here but I'm not sure why I can't seem to find a button to upload images... Regards, Siripen
  13. Hi, I have built a 1d/2d model with extended sections in ISIS model and link to TUFLOW but found that there is a 'jump' in water level between between the two ISIS nodes going from ISIS to TUFLOW. I have tried to applied an 's' flag on the hx lines along the floodplain but it doesn't seem to make any difference. The attached long profile shows that the water level 'jumps' from node CHE0_029(ISIS only extended section) to CHE0_030(ISIS/TUFLOW). I use the normal method of linking using hx line. (HX line in pink, CN line in green, CD polygon in blue, ISIS node in red) Any suggestions to improve the transition at the boundary between extended section in ISIS to floodplain in TUFLOW, please?
  14. Thanks for your suggestions, PHA, and you are absolutely right that 2D-2D linking is more trouble and time consuming than it's worth especially with the direct rainfall method. We gave up and ran two separate models instead.
