This paper aimed to determine the effects of a pulse signal near-fault ground motion on dynamic response gravity dams, including dam-reservoir-foundation interaction, using different reservoir modelling approaches such as Westergaard, Lagrange, and Euler. As case study, Sarıyar concrete dam located Sakarya River, 120 km northeast Ankara, was considered for investigating ground-motion responses....

Field observations imply that accumulation and advection of invertebrate larvae and other plankton by propagating fronts provides an efficient mechanism for the cross-shelf transport and subsequent coastal settlement of larvae and plankton. Gravity currents propagating into a heavier, uniform-density fluid are known to have near-surface velocities u that exceed the propagation speed c of the gr...

We deform gravity with higher curvature terms in four dimensions and argue that the non-relativistic limit is of the same form as the non-relativistic limit of the theories with large extra dimensions. Therefore the experiments that perform sub-millimeter tests of inverse-square law cannot distinguish the effects of large extra dimensions from the effects of higher dimensional operators. In oth...

This study analyzes the possible modes of seismic wave for concrete gravity dams and damage occurring in body where two dam sections are taken as a case study. Model (1) is typical section dam, while model (2) provided with specified steps at its base. The design waves included Operational Base Earthquake (OBE), Maximum Design (MDE), Credible (MCE) levels. body-foundation-reservoir water intera...

The collision of a gravitationally-driven horizontal current with barrier following release from confining lock is investigated using shallow water model the motion, together sophisticated boundary condition capturing local interaction. permits several overtopping modes: supercritical, subcritical, and blocked flow. analysed both mathematically numerically to reveal aspects unsteady motion comp...

This paper presents experimental and numerical investigations of the seismic failure reinforced unreinforced monoliths Huangdeng concrete gravity dam. To verify scale factors, we use suitable materials (emulation material fine alloy wire) to simulate dam steel reinforcement (SR) in a scaled experiment model that includes water-retaining monolith overflow We design shaking table tests based on s...
