Experimental Investigations of Air Entrainment in Transition and Skimming Flows down a Stepped Chute: Application to Embankment Overflow Stepped Spillways [PDF]

open access: yes, 2001
Stepped spillways have been used for about 3,500 years. The last few decades have seen the development of new construction materials, design techniques and applications : e.g., embankment overtopping protection systems.

Flow Resistance in Skimming Flows and its Modelling [PDF]

open access: yes, 2002
Dams and weirs must be equipped with adequate flood release facilities for a safe dissipation of the kinetic energy of the flow. With stepped spillway design, it is essential to predict accurately the flow resistance associated with the steps.

Designing Roller compacted concrete (RCC) dams

open access: yes, 2018
Concrete is the most common building material in the world and it consists of aggregates,cement and water that harden over time, it is also known as a composite material. The use ofconcrete is very versatile due to its resistance to wind and water and its ability to withstandhigh temperature.

Utilisation of Stepped Channels and Study of Stepped Channel Flows in Australia [PDF]

open access: yes, 1998
Stepped channels and spillways are used since more than 3,000 years. Recently, new construction materials (e.g. RCC, gabions) have increased the interest for stepped chutes.

Carbon nanotube, graphene, nanowire, and molecule-based electron and spin transport phenomena using the non-equilibrium Green function method at the level of first principles theory

open access: yes, 2007
Based on density functional theory (DFT), we have developed algorithms and a program code to investigate the electron transport characteristics for a variety of nanometer scaled devices in the presence of an external bias voltage.

Dynamic response of Akcakoca RCC Dam including galleries

open access: yesJournal of Structural Engineering & Applied Mechanics
Dams are structures that demand a significant amount of concrete, making them costly constructions. Hence, various alternative methods are employed for dam construction, one of which is the use of Roller Compacted Concrete (RCC). This is a case study, which focuses on examining the behavior of RCC dams with and without galleries under seismic ...
