C10.1 February 1998 saw the failure of the earthen dam impounding California Jim’s Pond in southern Rhode Island.
The resulting flood raised temporary havoc in the nearby
village of Peace Dale. The pond is 17 acres in area and 15
ft deep and was full from heavy rains. The breach in the
dam was 22 ft wide and 15 ft deep. Estimate the time required for the pond to drain to a depth of 2 ft.
C10.2 A circular, unfinished concrete drainpipe is laid on a slope
of 0.0025 and is planned to carry from...
