This experimental study analyzes submerged hydraulic jumps generated in a 1.05-m wide stilling basin that receives overflow rectangular impinging jets, with the vertical distance between sharp-crested weir and bottom of plunge pool being 2.20 m. Five downstream non-developed nappe jets were analyzed, falling distances to break-up length ratios 0.76 0.78. The impingement velocity range was from ...

Structures like blunt-nosed chevrons, log deflectors and double-winged frames help in modifying the flow regime channel by concentrating increasing navigability. Moreover, they create scour pools downstream stilling basin, which can be used either as fish refuge or an in-stream storage site for previously dredged material. In this respect, use of wood debris form bundles has gained attention ab...

The Cuatro Ciénegas Basin (CCB) is a rare oasis in the Chihuahuan Desert in the state of Coahuila, Mexico. It has a biological endemism similar to that of the Galapagos Islands, and its spring-fed ecosystems have very low nutrient content (nitrogen or phosphorous) and are dominated by diverse microbialites. Thus, it has proven to be a distinctive opportunity for the field of astrobiology, as th...

Advanced oxidation processes (AOPs) have led the way in the treatment of aqueous waste and are rapidly becoming the chosen technology for many applications. In this paper, COD reduction potential of leather tanning industry wastewaters by Electro-Fenton (EF) oxidation, as one of the AOPs, was experimentally evaluated. The wastewater sample was taken from an outlet of an equalization basin in a ...
