The data for +this curve was generated from the topography and boundary definition +file provided in the @file{demo} directory. + +Together, the rating curves establish the connection between water level +and discharge at the boundary. The @emph{makeBoundary} program +identifies the panels that are filled and the panel that is part-filled. +The discharge in the part-filled panel is set so that the sum of the +discharge values is equal to the target flow. The last step is to +interpolate the water level from the rating curve of the part-filled +panel. + @node Demos, GNU Free Documentation License, Boundary Definition File, Top @comment node-name, next, previous, up @chapter Demos -- cgit
