Repeat Example 9-5 using the same data except that the two subbasins (Upstream and Downstream) are 2.85 mi2 each now (changed from 2.0 mi2 each). All other data remain unchanged. This will necessitate extending the existing overbank regions of the Preexisting-and Existing-conditions cross sections along the same slopes to properly analyze the behavior of the channel in steps 1 and 2. In step 3, increase the bottom width of the Proposed cross section beyond 10 ft, keeping the same 4:1 side cross slopes, until the flow is contained within the channel banks. Adjust the weir and detention basin geometry as needed in step 4 to fully mitigate the impacts, as described in the example.
