I'm currently working with HEC-HMS and i'm trying to use the gridded SCS Curve Number. I arrive to import my raster Curve Number as DSS file in HEC-HMS. But when I land my compute it doesn't work. The message error is the following : "ERROR 40509: No grid cells for gridded subbasin "S_1"." But i'm sure my DSS file got value. I'm sharing a picture of my DSS file with the publication. Thanks in advance for answering me. enter image description here Have a nice day
It tried different gridded curve number but I always got the same error. I also tried on 2 vesrion of HEC-HMS (4.7 and 4.10) but the same problem appear.
