In this study, reservoir water level effects on nonlinear dynamic response of concrete gravity dams are investigated. For this purpose, the nonlinear behavior of the dam concrete is captured using the concrete damage plasticity (CDP) on the non associated flow rule assumption. Water in the reservoir is represented by the Lagrangian (displacement-based) fluid finite elements. The program ABAQUS ...
Dam safety is an important issue as it directly influences environmental and life losses. Embankment material embankment core are factors that contribute to determining the size hydraulic characteristics of breach occurs due dam failure. The current topic present analysis impact materials properties on dimensions overtopping failure using 2D-HEC-RAS software with aid RAS-Mapper. was made by Dig...
The design of dams requires comprehensive studies to ensure the safety and feasibility these important engineering projects, as any possible failure case may lead considerable losses in human life properties. Specifically, analyses should be performed evaluate seepage, slope stability, soil liquefaction large earth dams. In this study, numerical modeling, based on finite element methods, was us...
Current formulas for calculating scour depth below of a free over fall are mostly deterministic in nature and do not adequately consider the uncertainties of various scouring parameters. A reliability-based assessment of scour, taking into account uncertainties of parameters and coefficients involved, should be performed. This paper studies the reliability of a dam foundation under the threat o...
Detection of early warning signals for the imminent failure of large and complex engineered structures is a daunting challenge with many open research questions. In this paper we report on novel ways to perform Structural Health Monitoring (SHM) of flood protection systems (levees, earthen dikes and concrete dams) using sensor data. We present a robust data-driven anomaly detection method that ...
Windows TM Dam Analysis Modules (WinDAM) is a set of modular software components that can be used to analyze overtopped earthen embankments and internal erosion of embankment dams. These software components are being developed in stages. The initial computational modules address routing of floods through the reservoir with dam overtopping and evaluation of the potential for vegetation or riprap...
