    Rating Curve

    I have attached the Excel sheet of HEC calculations, which shows that at profile 8 the the WSEL is above 335 m for the lateral structure but for the culvert it is still below 335 m so there is no weir flow. There is no submergence effect coz the d/s water level is well below the crest(335m)...

    SMIAH, but why is the shape of the curve different in excel and HEC? at some point in HEC the C value seems to be less and the curve rises rapidly for less discharge, which is not the case for Excel.

    Rating Curve

    Hello everyone, I have attached a rating curve which i developed from HECRAS and Excel for a lateral structure (spillway) which drains into a culvert, the crest elevation of spillway is 333 meter and that of the roadway is 335 m. I took a C value of 1.44 (SI) assuming the spillway as broad...
