In this article, a digital twin is numerical model of dam–foundation system with physical basis. A exhibits complex behavior and, therefore, significant simplifications are necessary for to be feasible, which reduces model’s accuracy. Differences in the material characteristics particular regions dam and foundation usually not considered. An important reason that high computational cost calibra...
sange siyah dam is located two kilometers down the kabod khani village. the environ of ghorrve city in kurdestan province. this is an clay core dam. in this dam instrumentation is performed in three section and consist of electrical piezometers, total pressure cells, settlement cells and so on. the main objective of instrumentation is to control the behavior of dam body and foundation, end else...
Uplift and pore pressures are fundamental loading conditions that affect the strength and stability of concrete dams. Historically, these loads have been difficult to quantify and to implement in finite element analysis (FEA). Some dam design guidelines propose different techniques to apply the estimated uplift pressure for its use in FEA of concrete dams. These methodologies are, in general, q...
Arch dams have delicate sections thanks to their curvature. The fact that these are large, costly and construction takes many years increases the importance of structure. Mistakes / or accidents may occur during such structures major loss life property. Considering volumes, masses slenderness arch dams, they can be significantly affected by dynamic forces as changing water pressure, temperature...

Many countries are implementing new dam safety regulations that often include more restrictive standards. This, together with the increasing average age of dams, results in a greater need for dam control and maintenance works. The advances in information and communications technologies improved the performance of dam monitoring systems, so a large amount of information on the dam behaviour can ...
