Abstract The use of carbon nanotubes (CNTs) to reinforce cemented rockfill is attracting considerable interest due the remarkable improvement in performance and extremely low dose added nanomaterial. To reveal enhancement mechanism CNTs on rockfill, acoustic emission (AE) characteristics specimens during Brazilian split test were investigated. results demonstrated that improved tensile strength...

Among the structural and non-structural methods of flood control, rockfill dams are a kind of detention structures that increase travel time and reduce the maximum instantaneous flood discharge. Due to the rapid and automatic effect of these dams, flood reduction happens more quickly. In this research, the best arrangement of rockfill dams at Taleghan basin was determined based on the cost of r...

rockfill dams are accounted as useful measures in watershed management projects. how-ever, the sediment transport through the rockfill materials, could impact their lifetime duration. previously, researches have been conducted to describe the various hydraulically issues of the flow passing through these structures however; there is no general relationship to estimate the sediment transport rat...

Abstract Rockfill dams with stone pitching are specific hydraulic structures generally built in the early XXth century where stones used to be hand‐placed without mortar constitute upward and downward dam faces. Few studies have been carried out quantify critical role of stability against both static seismic forces. Herein, a numerical model is proposed pseudo‐static tests performed on four dif...
