Two Pass InfoSewer Solution
Two Pass InfoSewer Solution The d/D you are Mapping is from the 1 st pass or the solution in which the manhole loads are calculated and the program estimates the flow in the links – the flow gives the value of d/D which you are mapping. The HGL plot is plotting the adjusted d/D which is the result of the 2 nd pass of the solution, this pass estimates backwater, surcharge and pressure and often the value of the Adjusted d/D is higher than the 1 st pass value of d/D. The Adjusted d/D is a better way of finding those pipes that are more than 0.75 full. Adjusted d/D is a better way of finding those pipes that are more than 0.75 full
