Abstract : The design of stable riverbank slopes along the Mississippi River is dependent upon the seepage conditions within the banks generated by varying river level, including sudden drawdown. Available seepage analyses are not adequate for the determination of the continuously changing free-water surface under time-dependent variations in river levels. A parallel plate viscous flow model was constructed and tested and was found to constitute a reliable means of obtaining the transient free surface within a sloping bank. Two series of model tests were performed using a vertical upstream face and an upstream slope of 45 degrees. (Author Modified Abstract)
