Water Surface Profile Uneven

Hi,

I am new to HEC-RAS, I am working on a small creek to calculate the water surface elevations and the top widths. The Water Surface Profile is suddenly dropping at a perticular cross-section, and when I delete that cross-section to verify if there is anything wrong with that perticular cross-section, then the WSProfile is dropping at the next upstream cross-section.

I am using steady flow data and subcritical regime, I even tried using mixed regime it does the same.

I even tried interpolating additional cross-sections on both sides of that C/S but still there is a steep drop.

Can any one help me out of this.
