Flood Protection Plans for Cumberland, Maryland & Ridgeley, West Virginia: Hydraulic Model Investigation

Report of a hydraulic model investigation "to determine the most economical method of providing protection for Cumberland and Ridgeley against floods somewhat greater than the flood of March 1936 Specifically, the model was used to determine: the proper sections and grades of channels required to pass the design flood with maximum reductions in flood stages; the minimum heights of levees and walls; and the channel treatment required at bridges to insure the safe passage of floodwaters with minimum alterations to the structures" (p. 4).
