  1. calberts, I am using a 1d boundary condition. The type of BC is water level height (ft) VS time. Another question is, what value should I use for Initial Water Level in tuflow. Because, a river or water body should have a specific baseflow or water level. So, what value should I use. Or I can leave it as default value (0) in tuflow.
  2. Dear all, I am doing hurricane sandy analysis over Camden, New Jersey. I have two boundary conditions. My problem is during tuflow simulation water is flowing inside the grid at downstream. That, must not happen in practical condition. Any one can help me regarding this issues? I am also attaching screenshot of two time step. The upstream BC is at the lower south. TIA --Fahad
  3. Hi, Actually it's quite easy in SMS. I figured it out by myself. You just need to draw a polygon in your study area. Use the create feature arc tool to do that. Next, you need to tell SMS that this closed arc is a polygon. You can do that by, Feature objects > Build polygon. That's it. So you have your rainfall input area. Now, you double click on the polygon and the window for rainfall input will open.
  4. Hi everybody, I have recently started using SMS. I have a question. I would like to use rainfall data (either gridded or point) as input instead of the "Flow vs. Time" upstream and "WSE vs. Time". Is it possible? Can anybody point me in the right direction? Any documentation I can read? Tutorials? TIA
  5. HI all experts, 1. I am kinda new to SMS. My problem is, in the tutorial TUFLOW 2D simulation the data for the boundary conditions (Flow VS time) and (Head VS time) are in cms and meter unit. But when I put the data into SMS bc part it says at top that the units are in cfs and foot. So, I need to convert the original data provided in SMS tutorial in feet and then put in to BC part in SMS? 2. Also, I exported a dem of my study area from arcgis in to sms and converted to 2d scatter. But the values are almost 3 times less than that of in Arcgis. In Arcgis the vertical unit is in State plane US feet projection (for new jersey). I checked the projection in SMS. Its still the same. Also I put the planar and vertical unit in SMS to US feet. Then why I am having this 3 times less value in SMS. 3. Another problem is my dem is very high resolution (10 ft). When I do the 2d scatter conversion my whole SMS crashed and my pc got hanged totally. I can't even move my mouse. I checked one time. And saw that all of my 8gb of ram is used. Now, I am only working with a very very small are by upscaling the DEM. This works actually. But ultimately I need to analyzed the whole area for my research. So, should I need a high performance computer to do this. Please help me. Thanks in advance. --Fahad
  6. Hi, I know it's really novice to ask. But anyway I am still learning. So, I am using the DEM (10m) downloaded from web service of SMS. I attached an image of that after converting the raster to 2d scatter. My question is what is the vertical unit of that data. Does SMS always shows vertical units in meter, because I think in the legend bar the values are in meter. I tried changing the vertical unit to US feet but nothing happens. Can the experts kindly help me in this regard? Thanks in advance. -Fahad
  7. Thanks a lot for your reply. I have successfully done that tutorial. My another question is I have coastal bathymetry file for New Jersey. As well as the DEM for New Jersey. Do I need to mosaic them into single file. Or it is not necessary to use bathymatry elevation file.
  8. I am quite new to SMS. I am trying to run a tuflow simulation over my study location. I have the DEM, landcover files for that area. Could anyone tell me the main steps in SMS that I have to do to run the simulation.
