Fill embankment failure under flooding conditions

In this chapter a summary of the present research is presented to the gained knowledge as a result of investigating seepage through a geneous embankments. Conclusions, came out of the present recommendations for further suggestede analysis of groundwater and seepage flow is an important design ’on in water engineering works. The main objective of this research . ize the finite element technique to develop a numerical model forting the seepage flow through fill embankments. The present h include seven chapters covered all the topics. A historical e review of the previous works related to the research was carried e literature focused on seepage and groundwater flow problemspecial emphasis on the various causes leading to embankment or failure as it categorized into three failure causes, hydraulic seepage failure, and structural failure. In the present research, . g two dimensional steady state unconfined seepage flow through ents was performed using the finite element technique as a al method. The governing equation of flow through porous mediaderived and then formulated as a finite element process. A computer gram using the F ortran-77 language based on the finite element hnique was developed to handle the considered investigated problem. erimental work was performed to investigate the seepage flow ugh embankments using the Permeability and Seepage Model at the draulics and Fluid Mechanics Laboratory, Faculty of Engineering, azig University in Zagazig. The experiments considered different s of soil through the different cases. A dimensional analysis was done ,obtain the dimensionless parameters, which claritY the seepage •ables. A verification of the developed finite element model was done the results taken from the experimental data where, it was compared the obtained results from the finite element model for the differents of soil and through the different cases. Applications of the model introduced at different sections of Ismailia canal, where it gave hing results. The following result is obtained from this research, lopment and verification of a two-dimensional finite element model e case of steady state condition using Galerkin’s principle andAccording to the research presented and through the analysis of the . ed results, the most important conclusions can be summarized as1) A good agreement was proved between the finite element solution resulting from the computer program and the experimental results using the Permeability and Sepage Model.
