    How would you go about modeling a sharp drop in a channel (e.g. concrete)? Say you have a 2′ drop over a 2′ distance. TIA!

    It depends. If your drop will be highly submerged (tailwater depth is appreciably higher than the brink elevation) then just model it with cross sections. One upstream of the brink, and one downstream. Otherwise, you might try using an inline structure.
