Hello,
I am setting encroachments using Method 1 in v5.0.3. At a couple of structures, the upstream surcharge value for many cross sections exceeds 2 or 3 feet and cannot go below 1′, even at the WS limits. I noticed that if I manually set the encroachments outside of the WS limits, it alleviates the US surcharge. Interestingly, the further away from the WS limits I set it, the more it alleviates the US surcharge. Why are the US WSEs proportionally affected by the encroachments even though they are not contacting any conveyance?
Thank you!
