I’m using a Quasi-Unsteady to model reservoir sediment in HEC-RAS.
When I run the model for sediment analysis, I’m facing the same error over and over again at a specific cross-section. The error is “Unrealistic Vertical Adjustment”. The cross-sectional area of the said section is smaller than the rest of the reach and it is the most upstream section. I tried changing the contraction and expansion coefficients, but the error persists. Please give me suggestions.
