Spillway berfungsi umtuk melimpahkan kelebihan air yang akan dibuang, sehingga kapasitas bendungan dapat dipertahankan sampai batas maksimum. Penelitian ini bertujuan untuk mengetahui debit banjir serta alternatif dari bangunan pelimpah (Spillway) Bendungan Pamukkulu dengan Tipe Mercu Bulat. Curah hujan rata-rata daerah dihitung metode Polygon Thiessen. Dan dianalisis perhitungan curah rancanga...

Hydraulics has been at the forefront of science for centuries. In this paper, new exciting developments are presented in terms of energy dissipation and multiphase flows. These include the hydraulic design of rectangular dropshafts and stepped chutes for embankment dams, and new air-water studies of spillway flows and dam break waves. The findings demonstrate innovative hydraulic research which...

1 Discussion Verification and Validation of a Computational Fluid Dynamics (CFD) Model for Air Entrainment at Spillway Aerators By M. Cihan AYDIN and Mualla OZTURK, Canadian Journal of Civil Engineering 2009, 36, 826-838.

The goal of this research was to determine the impact a pooled and flat stepped spillway on energy losses. FLOW3D, which is computational fluid dynamics (CFD) program, with mesh size 0.015 mm used for purpose. First, code tested against an available experimental model data both water flow depth inception point position. outcome precisely shows agreement laboratory work. Second, dissipation resi...

AbstractDams are civil structures essential to modern civilization. However, they can be a threat if not properly designed and operated. A particular risk that potentially lead dam failure i...

In arid regions, the construction of hydraulic structures is relevant due to shortage water resources. Using example Pskov hydroelectric power station, results calculation end structure energy spillway, made in form a well unique design, are presented. A culvert wall, with an initial expanding part and sloping spillway forming oblique forms well. The depths speeds each parameters jump calculate...

Air-water flow experiments were conducted on some flat and pooled stepped spillways with slopes of 8.9° and 26.6° in transition and skimming flows. The study comprised the observations of the flow patterns, characteristic air-water flow properties, and energy dissipation performances. The air-water flow properties showed some differences in terms of interfacial velocity, bubble count rate, and ...
