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 ...
The Ogee Spillway is one of the most crucial flood control structures, and it developed at same time as dams. Spillway's downstream portions experience scouring due to flow, a problem that persists in reality. This paper aims investigate hydraulic performance stepped block dissipater using three-dimensional simulation model. dissipated was given new distribution may be one, two, or three rows t...
A panel illustrating spinal cord injury in The Dying Lioness in the British Museum dates to 650 BC. This paper outlines the subsequent progression of knowledge of the anatomy of the spinal cord. The animal dissections of Galen are considered because his deductions persisted through the Dark Ages until the late 18th century. Anatomy advanced gradually to yield discoveries of the complex tracts a...
Dam break is considered as a major catastrophe with significant negative economic, social, and environmental consequences, thus must be prevented at any cost. Here, we report analyze near-miss dam incident in Toddbrook dam, England during the August 2019 flooding, where spillway of failed putting entire risk failure. A combination field surveys, desk studies numerical modelling applied to devel...
Water supply at a desired rate at any time to meet the water requirements regardless of river discharge must be considered in the general design of intakes provided that the needs do not exceed the river flow. Due to the lack of necessary information in this field and the importance of sediment transport to the lateral intakes at river bends, this study aimed at understanding the mechanism of t...
The lunar semidiurnal influence is already known for tidal rivers. The moon also influences inland rivers at a monthly scale through precipitation. We show that, for some non-tidal rivers, with special geological conditions, the lunar semidiurnal tidal oscillation can be detected. The moon has semidiurnal tidal influence on groundwater, which will then export it to streamflow. Long time series ...
