Because of different behavior of reservoir water and dam material, the determination of hydrodynamic pressure during earthquake is very complicated. Thus, different formulations have been presented for modeling of the dam reservoir system under dynamic loading such as earthquake. These formulations can be categorized into two general groups, which are Lagrangian and Eulerian, each having advant...

We present a detailed survey of the ongoing destabilization process of the Mosul dam. The dam is located on the Tigris river and is the biggest hydraulic structure in Iraq. From a geological point of view the dam foundation is poor due to a site geology formed by alternating strata of highly soluble materials including gypsum, anhydrite, marl and limestone. Here we present the first multi-senso...

Large dams, especially concrete dams, have been designed against earthquakes since the construction of Hoover dam in the 1930s. The design criteria and methods of analysis used in those times are outdated today and the actual seismic safety of these structures is not known in view of today’s requirements. Earthquake action was usually taken into account pseudostatically, through an inertia forc...

Interaction of concrete with the persistent prevailing environmental condition will alter its material properties and cause deterioration. There are various causes distress in structure, such as improper construction practices, post-construction expansion due to Alkali-Aggregate Reaction (AAR), corrosion reinforcement, non-homogeneity concrete, development cracks shrinkage thermal stresses, agi...

optimization techniques can be efficiently utilized to achieve an optimal shape for arch dams. this optimal design can consider the conditions of the economy and safety simultaneously. the main aim is to present an applicable and practical model and suggest an algorithm for optimization of concrete arch dams to enhance their seismic performance. to achieve this purpose, a preliminary optimizati...

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...
