Internal erosion under spillway rested on an embankment dam
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...

متن کاملEmbankment dam spillways and energy dissipators
For the last fifty years, the design floods of a number of embankment dams were re-evaluated and the revised spillway outflows are often larger than the original design discharges. Several embankment overtopping protection systems were developed for earthfill structures, and the applications range from river dykes to tsunami protections including embankment dams. Well-known designs include timb...
متن کاملForecasting embankment dam behaviour with artificial intelligence
Forecasting dam behaviour is of paramount importance to avoid collapses. It consists of detecting and controlling deterioration mechanisms. This paper sets out to propose a multi model methodology to model complex dynamic systems, such as dams. It defines three models based on expert knowledge: a structural model, a functional model and a behavioural model. They are developed from the stories o...
متن کاملSeismic Behavior of Zoned Core Embankment Dam
The aim of this investigation is to study the dynamic behavior of a zoned core earth-fill dam. Due to lack of suitable clay materials, the Mamloo dam is designed as zoned core that is composed of three vertical zones including central lean clay (CL) core and two sides clayey gravel (GC) layers. Seismic behavior of dam was analyzed in two cases including homogenous clayey core and zoned core by ...
