abstract rockfill dams are usually used for affecting the flood and reducing the peak discharge. the materials used in these dams will usually make the flow turbulent, therefore darcy's law can not be used for this kind of dams and the equations based on the non-darcy flow must be applied. non-darcy flow equations are showed in two general ways including: and .one of the main parameters for flo...

This article presents experimental research focusing on the structural failure of central core a rockfill dam using sand-bentonite mixtures. It comprised an extensive geotechnical characterization soil materials and mixtures, including compaction strength tests, as well construction 1 m high 1.5 wide physical models. The displacements cohesive cores were recorded tailored measuring system, base...

Dam settlement monitoring is a crucial project in the safety management of concrete face rockfill dams (CFRD) over their whole life cycle. With development an automatic system, large amount data was collected. To precisely predict structural health dams, combined multiple points (MMP) model and machine learning has been developed. In this paper, based on physical factors CFRD, we comprehensivel...

There are increasing demands from dam safety regulations and guidelines to upgrade the rockfill dams, especially in Norway where over 180 large dams present. To protect hydraulic structure against overtopping events or leakages, it is important use defence mechanisms such as a protective layer of riprap on downstream slope. In this article, we display 9 experimental setups riprap, conducted at ...
