Johnson. 176 P. DISS THESES (PH.D.) -- University Of Sheffield, Department Of Civil And Structural Engineering, U.K., 1983 A model testing technique for obtaining discharge hydrograph resulting from failure of an earth embankment is developed. Problem of time-dependent progressive failure due to variable lateral and vertical erosion rates is examined and a laboratory model, consisting of a series of small concrete blocks with different simulated erosion rates, is developed for simulation of washout process. A theoretical equation for initial discharge hydrograph generated for a particular ratio of lateral to vertical erosion rates, is developed and experimentally verified. hydrology / dams / erosion / floods Johnson, F.A., Supervisor University Of Sheffield, U.K. University Of Sheffield, U.K.
