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 ...

River Region of Baru-Kluet has a steep slope contour and high rainfall so that it is vulnerable to flooding while during the dry season rice fields experience drought due lack water. Therefore, dam built mitigate these issues. The spillway flow-control component in which used improve regulation enlarge flow rate will cross building. Spillway hydraulic behavior called cavitation. experiment was ...

Atmospheric gas saturation levels were monitored throughout a 40-km reach of the upper Colorado River during the summer and fall of 1995 to identify possible sources of gas supersaturation in the river. Gas saturation data from seven fixed sampling points and 40 random sampling points were analyzed using analysis of variance (ANOVA) and multiple regression methods. The lowest total gas saturati...
