Aside from the sediment rating curve and flow curve, is there a way for me to control the boundary conditions on entry? My simulation results tell me that the very first XS fills completely with sediment. My guess is that my suspension sediment on entry is too heavy to carry, since this problem occurs just at the first XS. Deleting the bigger diameters from the rating curve seemingly solves my issue, but I’m discarding necessary information from my model. Is there another way for me to solve this while keeping my rating sediment curve?
