Error in elevation of spillway

Sat, 02/03/2018 - 1:57am — Javad
Dear all; I am working on a dam and the reservoir has a spillway with elevation of 1267.5 m. When I check the run, it gives me this error: "Upstream centerline elevation [ESP=1267.500] > the top elevation of the grid [EL=1266.000] for spillway 1" What does this mean? Regards.

Your model grid needs to have an elevation that is higher than the spillway. Currently the top elevation at 1266 is less than the spillway (1267.5). You need to review your model grid. The W2ControlGUI tool that comes with the CE-QUAL-W2 download is useful for this, it allows you to see the grid elevations by segment and layer.

Thanks, I correct the elevation. Regards.
