Introduction
Emre Dumlu had worked as a scholarship in a TUBITAK project. He conducted piping experiments on embankment dams. During this period, he also performed piping simulations on PLAXIS. Emre is currently a graduate research assistant and Ph.D. student at Olemiss under Dr. Yavuz Ozeren.

Article
In this study, time-dependent finite element analyses of the breaching process in two homogenous earth-fill dams were performed using the finite element method. Breaching was initiated at the middle and corner sections of the upper part of the dam bodies. The numerical results were compared with the findings of the experiments realized on dams 60 c...

Piping and overtopping are the most important causes of earth-fill dam failure. Such dams may erode under seepage, causing a reduction in the structural strength. The aim of this study was to investigate the temporal evolution of the breach and flow rate from the breach resulting from the piping in earth-fill dams. The experiments were carried out...

One of the most prominent failure reasons for earth-fill dams is internal erosion resulting from piping. This failure mode may cause irreversible weakened structural integrity, loss of properties, and even loss of lives. Therefore, it is important to understand the breaching process due to piping by providing reliable data for the decision-makers i...

Piping is one of the most important causes of earth-fill dam failure. This study investigates the temporal evolution of the breach resulting from the piping in earth-fill dams by means of the image processing technique. The experiments were performed on dams constructed from a mixture of 85 % sand and 15 % clay. A circular tunnel with a diameter of...

One of the most significant reasons for earth-fill dam failures is internal erosion resulting from piping. This research was carried out as a part of a project supported financially by the Scientific and Technological Research Council of Turkey (TÜBİTAK). This paper involves the comparison of the experimental findings related to two different scena...
Article
Full-text available
One of the main factors that leads to earth-fill dam failures is the internal erosion, commonly referred to as piping. Regarding the geometry of the breach and the discharge of water flowing through the breach, many researchers working with numerical analyses in this field make some simplified assumptions. This study was carried out as a part of th...

One of the most significant reasons for earth-fill dam failures is internal erosion, often known as piping. This research was carried out as part of a project funded by the Scientific and Technological Research Council of Turkey (TÜBİTAK) and it involves an experimental investigation to look into the breach process and provide the data for more rea...
Thesis
Full-text available
Earth-fill dams have been constructed for decades by compacting natural soil materials near the dam site. Piping is of the most important causes of their failure. In the scope of this thesis, 2 m in length homogenous earth-fill dams were constructed in a rectangular flume in the laboratory of the Izmir University of Economics. The experimental and...

Internal erosion, also known as piping, is one of the most important causes of earth-fill dam failures. Many researchers dealing with numerical analyses in this area make some simplified assumptions about the shape of the breach and the discharge of water flowing through the breach. This study was conducted in the scope of the project supported fin...

Özet: Borulanma toprak dolgu barajların stabilitesini tehdit eden önemli ve karmaşık bir problemdir. Günümüzde borulanmanın karmaşık özellikleri nedeniyle erozyon sürecini tarif edecek genel bir formül mevcut değildir. Bu çalışma kapsamında, toprak baraj gövdesinin üst köşesindeki sızma nedeniyle oluşan borulanmanın gelişimi deneysel olarak araştır...

Porsuk Stream is the longest branch of the Sakarya Basin which originates from Murat Mountain and bypasses the provinces of Kutahya and Eskisehir. Based on recent increasing pollution concentrations reported in the literature, the main river is experiencing problems with decreased water quality. In this study, hydrodynamics and water quality parame...

Piping is one of the main problems which threatens stability of earth-fill dams. Realistic approaches are needed for breach mechanism as well as breach geometry and flow. The aim of this study is to realize experiments to provide data needed to perform numerical analyses by making more realistic assumptions. Dam having a height of 0.6 m, a bottom w...
