manaye 0 Report post Posted May 14, 2010 We are trying to abstract flows from streets digitized as polygons. What we want is just to take away flows from a 2D cell by using an SH boundary. We have specified an QH curve in the database. The model is running fine but it doesn't look that it is abstracting any flows. Are we missing something?

Bill Syme 0 Report post Posted May 20, 2010 Hi Manaye I'm not sure a SH will do what you want in this case. The abstraction is based on the water level (not depth) - is this what you would like to do? Also check your 2d_bc_tables_check.csv file to make sure the flow vs water level curve has been correctly interpreted (it's a common mistake to have flows in Col 1 and water levels in Col 2 when it should be the other way round).
