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...

Abstract Otolith strontium:calcium ratios were used to trace lifetime movements of American eels (Anguilla rostrata) captured in salt-water bays and adjoining freshwater ponds in Prince Edward Island, Canada. Eels were classiWed into migratory contingents based on their movement patterns. A pond with a pool-and-weir salmonid Wshway and a pond drained by a low-gradient channel contained eels tha...

Shock waves are generated downstream of spillways during flood operations, which have adverse effects on spillway operations. This paper presents the physical model study shock at Mohmand Dam Spillway project, Pakistan. In this study, hydraulic analysis was carried out to investigate its generation mechanism. Different experiments were performed analyze rooster tail a flat chute and examine fac...

Abstract The paper concerns with the relationship between cavitation inception бi and sound pressure level (SPL). A case study of Xiaolangdi Hydro-project has been taken as a typical example, which demonstrates the standard criterion of SPL indicating cavitation inception. Cavitation inception of an orifice plate used for energy dissipation in a tunnel spillway has been witnessed and verified b...

At 8 to 15 kilometers wide, Ma'adim Vallis is one of the largest valleys in the martian highlands. Although a groundwater source was previously suggested, the channel originates at a spillway in the divide of a approximately 3,000,000-square-kilometer closed drainage basin. The interior morphology of this source basin, including likely shoreline features following topographic contours, suggests...

Overview In free-surface flows the turbulence in the liquid may be sufficient to disturb the surface to the point of entraining air into the flow. This process is important, for example, in water treatment where air is needed to sustain microorganisms for water purification and in rivers and streams for sustaining a healthy fish population. Air entrainment is typically engineered into spillways...
