Stochastic Analysis of Steady Seepage Under Heading-Up Structures Amro M. M. Elfeki Abstract: A probabilistic approach has been followed to study the uncertainty in predicting uplift pressures under hydraulic structures and the flow field in terms of hydraulic heads The uncertainties considered in this paper include the geological structures and the bedding characteristics. Both horizontal and inclined bedding with different degrees of inclinations have been treated The mean and standard deviation of the hydraulic head field, uplift pressures and total seepage rate under the floor are estimated using Monte-Carlo approach. It has been shown that the uncertainty in predicting the flow field do not depend only upon the contrast in heterogeneity of hydraulic conductivity but upon the bedding inclination as well. The higher the magnitude of the angle of inclination the greater the uncertainty. The maximum uncertainty appeared in case of inclined bedding with 45 degree. Monte-Carlo simulations as used in the current study can be applied in the same way to other particular situations which are not covered in that study
