FLOODS RESULTING FROM SUDDENLY BREACHED DAMS. CONDITIONS OF HIGH RESISTANCE. HYDRAULIC MODEL INVESTIGATION

Abstract

The purpose was to obtain experimentally stage and discharge hydrographs both at and downstream of simulated, suddenly breached dams. Aluminum strips were added to the flume floor and sides to provide a rougher channel than that used in the first series of tests. Observations of stage versus time were made for each of several test conditions at recording stations upstream from, at, and downstream from the dam. Velocity versus time observations were made at recording stations downstream from the dam. Discharge-time hydrographs were calculated for flow through the breach and at selected stations downstream. Conclusions were reached regarding the maximum flow through a given breach, the maximum stage at the breach and at stations downstream from the dam, the propagation of the negative wave up the reservoir, and the shape, velocity, and propagation of positive flood wave downstream for a channel of high resistance to flow.
