Embankment drainage after instantaneous drawdown

Newlin, C.W. / Rossier, S.C.

Method is presented for use in determining position of saturation line and percent drainage in upstream portion of earth dam following complete or partial drawdown of reservoir based upon -- dimensionless time factor which is function of elapsed time, permeability, effective porosity, and boundary conditions, and drawdown ratio which expresses drop in reservoir elevation as function of original height of water above slope; expressions are derived for predicting effect of partial drawdown; model studies indicate that hyperbolas related to coordinate system, which is function of time factor and drawdown ratio, can be used to define saturation line.
