Ecological dams: Concept, transformation, and developmental pathways of dam projects under the framework of river ethics

open access: yesRiver, EarlyView.
This figure elaborates the scientific connotation and systematic construction path of ecological dams. Adopting a full‐cycle analysis framework centered on ecological impacts and benefits throughout the project lifecycle, it covers four key stages from planning to post‐completion, with core focuses on risk avoidance, impact control, ecological health ...

Clear-water scour at a side-weir intersection along the bend

open access: yes, 2005
The present study focuses on the local depth of clear-water scour at a side-weir intersection located on the curved part of an alluvial channel for each 30 degrees angle along the bend.

An Experimental Study on the Effect of Distance and Sheltering Area of a Group of Linearly Arranged Sacrificial Piles on Reducing Local Scour around a Circular Bridge Pier under Clear-Water Conditions

open access: yesFluids
One of the major problems associated with bridge piers is ensuring their safety against local scouring caused by the erosive action of flow. Numerous countermeasures have been developed and tested to solve this problem, among which sacrificial piles are ...

Local Scour at the Elliptical Guide Banks

open access: yes
Scour development in time at the elliptical guide banks during the floods was studied. The dimensions of the upper part of the elliptical guide banks, namely the turn and length, were calculated by the Latishenko method.

Camels as a Climate‐Resilient Linchpin for Sustainable Development in Global Drylands

open access: yesSustainable Development, EarlyView.
ABSTRACT Camels represent a significant, yet underutilized, asset for advancing integrated sustainable development in the world's expanding drylands. Previous reviews have examined camels' physiology, milk composition, or pastoral systems in isolation; this review examines their potential as a climate‐resilient linchpin for food systems by synthesizing

Scour Development and Bridge Abutment Safety during the Floods

open access: yes
Bridge crossings on plain rivers were modelled and scour development at the abutments and guide banks were studied. Tests were carried out in flumes 3.5 m wide and 21 m long in clear water conditions for FrR = Frf.

Effective Equilibrium Reaction Zone Modeling of Hydrogen Plasma Smelting Reduction: A Scenario Analysis

open access: yessteel research international, EarlyView.
The study presents a dynamic zonal model for hydrogen plasma smelting reduction (HPSR) in direct current arc furnaces, predicting time‐dependent behavior of metal, slag, and off‐gas. The study considers various industrial scenarios to quantify energy demand, hydrogen utilization, degree of reduction, and other operational sensitivities.

Temporal scour evolution at wood bundles under clear water condition

open access: yes, 2023
In the current scenario, there is a rapid degradation of the various water resources due to a host of climatic and anthropogenic factors. Natural river channels are particularly destabilized, leading to recurrent siltation and flood problems.
