Conference Paper
Full-text available
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...
Conference Paper
Full-text available
Estimation of peak discharge is a key parameter for risk assessment in case of dam failure, and has attracted great attention from researchers in recent years. Many formulas are available in the literature, but these cannot cover all experimental scenarios. Existing models are typically inadequate to address the complexities of dam breaches. This r...
Conference Paper
Full-text available
Piping is one of the most important causes of earth-fill dam failure. Such dams may erode under seepage, causing a reduction in the structural strength. This study is a part of the project TUBITAK 119M609 supported financially by the Scientific and Technological Research Council of Turkey. The aim of this project is to investigate the temporal evol...
Conference Paper

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...
Conference Paper

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...

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...
Conference Paper

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...
Thesis
Full-text available
From the past to nowadays, earth-fill dams have been built thanks to their advantages, however, piping is a problem that earth-fill dams can experience and then fail. While there are many studies about the overtopping failures of the dams, there are not too many surveys about dam failures due to piping. Dams having a height of 0.6 m, a bottom width...
Conference Paper

Piping is one of the main causes of the earth-fill dam failures. Most of the researchers realizing numerical analyses make some simplified assumptions concerning the shape of the breach and the discharge of water flowing through the breach. The aim of this study is to realize experiments to provide data needed to perform numerical analyses by makin...

Conference Paper
Full-text available
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...
Conference Paper
Full-text available
It is important to predict sediment load in advance for effective management of the reservoirs and river, including determination of the capacity of the dam reservoirs, design of flood protection structures, drought and watershed management, and conservation of natural life. This research presents alternative approaches, in particular, Multilayer P...

Su kaynaklarını korumak ve verimli bir biçimde kullanabilmek için mevcut su kaynaklarının gelecekteki miktarlarının iyi tahmin etmek gerekmektedir. Akarsuların akımlarının doğru tahmini, baraj haznelerinin kapasitesinin belirlenmesi, taşkın koruma yapılarının tasarımı, kuraklık ve havza yönetimi, doğal hayatın korunması gibi birçok toprak ve su kay...
