Re: Contraction and Expansion Reach Lengths for Bridges
Through may reading to the
Application Guide - Example 3 Single culvert (Multiple Identical Barrels)
There is explanation In pg. 3-6 "Estimating of the expansion reach length".
In Fact I tried to understand how the value "B- total floodplain width = 145" and how the Average length of the side obstruction was estimated " (the values 925, 1070) .
Unfortunately i did not under stand where those numbers came from?
