Dear All, I am reading HEC-RAS solution for the purpose of delineating the floodplain. When I read the solution I get a message a couple of times that some given cross sections do not exist in WMS database and then WMS continues to read the solution but creates a blank scatter plot with one empty PF 1. I checked the solution in HEC-RAS and for each cross section (including the extra ones I created in HEC-RAS by interpolating existing cross sections) there are all the parameters including the velocity, ground elevation and water surface elevation. I would appreciate any suggestions. Thanks.
