Effective Drainage

This paper presents an experimental study of a homogenous earth dam. The work is focused to the search of solutions of problems encountered in the earth dams after their construction. One of the major problems is the choice and design of systems of drainage. The effective drainage system to prevent harmful accumulations of excess water is one of the most important roles of dams. Efficient drainage systems can improve the safety of earth dams. The paper presented herein reports the results obtained from the experimental study. Empiric relations have been obtained which can be help in the control of the flow rate in the chimney drain of the earth dams on pervious foundation, which can increase safety earth dams

Abstract The analysis of the failure due to the effect of the propagation of normal and reversed faults with different angles of inclination and by sliding through the Ourkiss dam isstudied numerically. Mainly at the end of construction and at the highest water level, for this purpose the non-linear finite difference method is used considering four fault angles of inclination, activated at the center of the base of the embankment.The results of the study show that the shear stress values increase with the increase of the vertical base displacement imposed in both conditions of the dam state, and this for both normal and overturned faults.

First Results

The objective of this study is to simulate the tidal circulation in the coastal area Casablanca-Mohammedia located on the Moroccan Atlantic. Simulations of the tidal currents of this zone use the 2D version of the MECCA (Model for Estuarine and Coastal Circulation Assessment). These simulations are based on the depth-integrated dynamical equations of turbulent motion. Equations are solved by using the implicit finite-differences techniques. The modelincorporates the actual bottom topography and the effects of the Earth rotation. As forcing mechanism, the model uses the tidal heights prescribed along the open boundaries.As first results, numerical experiments show that the model provides good results compared to those of the altymetric model TPXO.

The earth dam of run-of-river unit - Kuybishevskaya hydro-electric power station on Volga - is viewed. The main characteristics of earth dam, particularities of its construction and exploitation are presented. The factors that have changed initial design specifications of its exploitation are highlighted. Evaluation of geometrics of earth dam in different exploitation periods and potential causes of their tolerance are analyzed. Measures for exploitation reliability growth are proposed.

The concrete cutoff wall is a technology used in reinforcing sick dams more usually in recent years. In the text, the advanced FLAC3D method which is based on 3-D explicit finite difference method, is used to simulate a reinforcement of earth dam using concrete cutoff wall. Through the simulation, Mohr-Coulomb model, elastic model and Goodman element are used to analyse the distribution of the stress and the strain of the dam before and after reinforcement. Consequently, we can evaluate the unti-seepaging effect and raise the possible question.
