In this study, based on data from instrumentation Kaboodval earth dam, pore pressure, stresses and the meeting of the dam construction period compared with the values ​​of numerical analysis. For this purpose, during the construction of the dam using Mohr-Coulomb model behavior, the softening, hardening model has been analyzed and pore pressure, stresses in the body and its meeting with instrum...

In the present study, physical model tests were conducted to investigate the effect of the geogrid reinforcement on the reduction of the differential settlement in widening of a highway embankment. A water bag filled with water and placed beneath an embankment was used to simulate the soft foundation of the widened portion of the embankment in the physical model test. Water from the water bag w...

in this paper we investigate the mechanism of internal erosion caused in the right abutment of the shahghasem dam’s spillway. shahghasem dam is an earthen dam located in yasouj, in southwest of iran. a significant hole and pipe have been observed in the corner of the right abutment from upstream view. the foundation is marlstone, which has low cohesion and susceptible for internal erosion and p...

Roath Park, in which. the lake is situated, is also noted for its recreational facilities and splendid botanical gardens, which include one of the finest rose gardens in Great Britain. An attraction of the lake up ...

Dam failures are examples of man-made disasters that have stimulated investigation into the processes related to failure different dam types. Embankment breaching during an overtopping event is one major modes for this type, comprising both earthfill and rockfill dams. This paper presents results a series laboratory tests on breach initiation progression in Especially eight 1 m-high 1:10 scale ...

Failure of dams due to overtopping is among the most frequent forms of embankment failures. Owing to massive and wide spread damage to structures and loss of lives associated with a dam failure, the subject has drawn the attention of scientists. The study also becomes essential for damage assessment and for development of early warning system of people downstream of the embankment. The rate of ...

The Red Rock Hydroelectric Project converted the existing Dam near Pella, Iowa, from a non-powered dam into multi-purpose dam. flood control was constructed by U.S. Army Corps of Engineers (USACE) in 1960s on Des Moines River Iowa. hydroelectric project developed Western Minnesota Municipal Power Agency and generates up to 55 MW with an average annual energy output 178 gigawatt-hours. new intak...
