An experimental study on angled trash screen in open channels

open access: yesAlexandria Engineering Journal, 2018
Trash screens are widely employed at entrance of hydraulic structures (culverts, barrages…, etc.), water intakes, and pumping stations to trap flowing debris that could instigate downstream troubles.

A Perspective for Ménière’s Disease: In Silico Investigations of Dexamethasone as a Direct Modulator of AQP2

open access: yesBiomolecules, 2022
Ménière’s disease is a chronic illness characterized by intermittent episodes of vertigo associated with fluctuating sensorineural hearing loss, tinnitus and aural pressure. This pathology strongly correlates with a dilatation of the fluid compartment of

Wave Propagation through a Submerged Horizontal Plate at the Bottom of a Water Channel [PDF]

open access: yesComputational Engineering and Physical Modeling, 2020
Vibrational study of fluid-structure interaction is one of the most widely used cases in engineering. In various industries, the effect of fluid on the structure and vice versa is necessary to investigate such as shipbuilding, ocean energy sources ...

Spreading of Antarctic Bottom Water in the Atlantic Ocean [PDF]

open access: yes, 2012
This paper describes the transport of bottom water from its source region in the Weddell Sea through the abyssal channels of the Atlantic Ocean. The research brings together the recent observations and historical data.

Tutorial for Stopped-Flow Water Flux Measurements: Why a Report about “Ultrafast Water Permeation through Nanochannels with a Densely Fluorous Interior Surface” Is Flawed

open access: yesBiomolecules, 2023
Millions of years of evolution have produced proteinaceous water channels (aquaporins) that combine perfect selectivity with a transport rate at the edge of the diffusion limit. However, Itoh et al.

Hydraulic flow through a channel contraction: multiple steady states [PDF]

open access: yes, 2007
We have investigated shallow water flows through a channel with a contraction by experimental and theoretical means. The horizontal channel consists of a sluice gate and an upstream channel of constant width $b_0$ ending in a linear contraction of ...

An experimental investigation of the impact of aquatic weeds trash racks on water surface profile in open channels

open access: yesWater Science, 2019
A considerable quantity of weeds is drafted with flow due to maintenance activities and moving vessels causing serious problem to hydraulic structures and hydropower plants along open channels. Aquatic weed trash screens are normally constructed upstream

Analysis of the evolution trends and influential factors of bankfull discharge in the Lower Yellow River

open access: yesScientific Reports, 2022
After the Xiaolangdi Reservoir (XLDR) was put into operation, new water and sediment conditions have improved the silting condition of the Lower Yellow River (LYR), but against this background, the flow capacity of the LYR has become more complex.

Experimental study and a physical model on the geomorphic response mechanisms of meandering rivers under progressive sediment reduction

open access: yesFrontiers in Earth Science, 2022
As influenced by human activities, including high dam construction, soil and water conservation, and sand mining in the upper reaches of rivers, the amount of sediment entering the lower reaches of the river decreases significantly.

Propagation and deposition of stony debris flows at channel confluences [PDF]

open access: yes, 2015
The fluid dynamics of stony debris flows generated in two small tributaries adjacent to each other and flowing into a main receiving channel was analyzed experimentally at a laboratory scale.
