Complete Example 6.10. In that example problem, water depths were required in the discharge channel until the water level was within 2 percent of normal depth. Depths were found at 2 ft and 7 ft downstream [separation distances ( ~L) of 2 ft and 5 ft ) but are still needed at distances of 17 fi and 57 ft downstream. Determine the depths of flow at these other two locations using
(a) The standard step method and
(b) The direct step method.
Has normal depth been reached (within 2 percent) in the last cross section? (Note: A spreadshee: program may be helpful.)
