Abstract The simulation of Concrete Gravitational Dam burst floods is an important research content in the field disaster prevention and mitigation water conservancy projects. Due to extreme rainfall, earthquake, structure failure etc., concrete gravitational dam usually breaks a short time period. break flood will give risk downstream communities. Taking Kaliwa Philippines as example, based on...

Abstract Seismic analysis of a fractured dam is generally complex problem. This paper presents an earthquake behavior investigation concrete gravity considering dam-reservoir--foundation rock interaction. The Koyna profile, located in India, adopted this study. nonlinear finite element analyses are conducted taking into account empty and full reservoir cases, to exhibit the hydrodynamic e ect w...

The spillway of the Swa earthen dam, constructed in Yedashe Township, Bago Region, Myanmar, collapsed suddenly on 29 August 2018 and resulted a huge flood to downstream areas causing fatalities displacement thousands localities. This study aimed assess breaching process terms parameters such as average breach width, failure time peak outflow, mechanisms. We analyzed event from changes site befo...

development throughout the world for thousands of years, providing water, controlling floods, irrigating crops, facilitating navigation, creating recreational opportunities, and generating motive power and electricity. By the end of the 20th century, about 45 000 large dams (>15 m in height) and an estimated 800 000 small dams had been built worldwide (WCD 2000), obstructing over 65% of fresh w...

DNA adenine methyltransferase (Dam) plays an important role in physiological processes of Gram-negative bacteria such as mismatch repair and replication. In addition, Dam regulates the expression of virulence genes in various species. The authors cloned the dam gene of Yersinia enterocolitica and showed that Dam is essential for viability. Dam overproduction in Y. enterocolitica resulted in an ...

The construction of a reservoir on large-thickness collapsible loess cover will significantly increase the occurrence dam break disasters. main reason may be that although gradation particle is not uniform. clay content less than 10%. Piping channels easily form under action force and collapsibility. Near-static liquefaction in body saturated condition lead to piping or loss soil strength. Ther...

The study of hypothetical dam failure simulates the flow volume released by a in partial or total collapse. calculations wave propagation over ground downstream eroded are performed fluid hydrodynamic simulation programs. In this sense, input data model can be summarized physical characteristics fluid, hydrograph and digital terrain (DTM). Thus, systematic review aimed to seek current bibliogra...
