  • Good Morning Mark,  It is hard to answer questions like this without being able to see your model, so take these with a grain of salt if I am way off on some of these assumptions.  Yes the embankment needs to be included in the underlying terrain as well as the 2D grid. I prefer to insert break lines ...

  • Mark, The embankment will behave as a wall in the 2D model provided the WSE on either side of the embankment remains lower than the embankment crest elevation. If the computed WSE rises above the crest the model will then "see" the embankment and calculate a discharge based on the weir parameters you ...

  • Folks: We are attempting to model two-dimensional flow in two channel transition areas connected by a culvert. The two areas are separated by an embankment. I noticed that if we add a 2D area connector to the model and specify the embankment properties in the same window used to enter the culvert ...

  • In San Bernardino county, I have seen gas companies requesting 12" vertical separation for standard distribution gas lines and as much as 24" vertical separation for high pressure gas transmission lines.  For standard gas distribution lines, I have experienced little resistance when requesting a variance ...

  • PLEASE design with maintenance in mind.  A little forethought now could save major headaches and repair costs later! ------------------------------ Maria Price P.E., M.ASCE Engineering Manager City of Chattanooga Chattanooga TN ------------------------------

  • Mr. Chien: I assume you are with a regulatory organization. Let go back to the beginning. All of the comments are spot on, but somewhat incomplete. I would not install a water line unless there was sufficient knowledge about the soils. I have seen soils so hot that the plastic wrap looked like it was ...
