I'm using Chow's "Open Channel Hydraulics" to calculate superelevation depths on a channel in a bend. The results give us Delta H. However, no picture is drawn showing what delta H is referenced to: is it on TOP of normal depth, or is it the height differential between the high and low...
If using a flowable fill/lean concrete mix for pipe bedding under deep burial, what is a proper value for the "soil modulus" used in burial calculations? I'm think it related to the modulus of elasticity of the bedding fill, but I'm not sure.
