Hydraulic jump used to dissipate excessive kinetic energy in natural water ways since the down of time. Screens fixed stilling basin control hydraulic location, depth and length from four decades ago. In this study, screens with a constant height different widths same screen relative area (Ar=0.285) were located behind gate at distance 10 cm tested under wide variance conditions submerged jump....

Overthe years, Sungai Bunus has undergone hydrological changes and become lower narrower. Under a flood mitigation project, diversion channel is proposed to reduce the volume of water in Bunusfurthermore avoid spill over into Klang flooding events Kuala Lumpur city. This research describes physical modelling flow state stilling basin. Physical model was constructed verify design criteria basin ...

A new species of fossil bumble bee (Apinae: Bombini) is described and figured from Early Miocene (Burdigalian) deposits of the Most Basin at the Bílina Mine, Czech Republic. Bombus trophoniussp. n., is placed within the subgenus Cullumanobombus Vogt and distinguished from the several species groups therein. The species is apparently most similar to the Nearctic B. (Cullumanobombus) rufocinctus ...

The scale invariance of natural images suggests an analogy to the statistical mechanics of physical systems at a critical point. Here we examine the distribution of pixels in small image patches and show how to construct the corresponding thermodynamics. We find evidence for criticality in a diverging specific heat, which corresponds to large fluctuations in how "surprising" we find individual ...

This study presents an investigation on the use of submerged counterflow jets as a means for stabilizing spatial hydraulic jump occurring in abruptly expanding channels. The characteristics flow downstream from stilling basin and main parameters influencing effectiveness device improving uniformity reducing scouring potential are examined laboratory tests, under several geometric configurations...
