Quarterly Journal of the Royal Meteorological Society, EarlyView.A theory for the interaction between a boundary layer and a low mountain is used to provide estimates of the turbulent orographic form drag, upward‐propagating mountain gravity‐wave drag, and trapped lee‐wave drag (case shown in the figure). After reviewing briefly how these processes are represented in weather and climate models, we propose a ...

Potential Impacts of Low Flows on Fish Foodscapes and Production in a Braided River
River Research and Applications, EarlyView.ABSTRACT Changes in river discharge affect the physical composition and connectivity of habitats which, in turn, may shape the spatial distribution of fish food abundance, accessibility and quality—the ‘foodscape’—of river ecosystems. However, the influence of river flows on fish foodscapes has received very little attention from scientists. We studied

A free surface finite element model for low Froude number mould filling problems on fixed meshes [PDF]
, 2011 The simulation of low Froude number mould filling problems on fixed meshes presents significant difficulties. As the Froude number decreases, the coupling between the position of the interface and the resulting flow field increases.

River Research and Applications, EarlyView.ABSTRACT Empirical evidence of population demographic responses to environmental perturbations is a major knowledge gap for aquatic vertebrate populations. Extensive habitat alteration including channelization of headwater streams influences the habitat template on which small‐bodied fish are dependent to carry out distinct life stages and maintain or ...

Analysis and Research of Aeration Capacity of the Spillway Tunnel with High Speed Flows
工程科学与技术, 2013 :The aeration capacity of the spillway tunnel with high speed flows was analyzed by model experiment from the macroscopic aspect.The results showed that the aeration capacity of the complement wind tunnel in the mid-gate chamber would not increase as the

The Role of Sediment Supply on Fish Habitat Dynamics of a Morphologically Active River Widening
River Research and Applications, EarlyView.ABSTRACT Restoration measures, such as river widening, aim to reactivate key morphodynamic processes, which are critical drivers of fluvial habitat dynamics. While some evidence supports the important role of sediment supply on river widening's morphology, its link to fish habitat availability and dynamics remains unclear.

Redistributive effects of unsteady flow regimes downstream of reservoirs
River, EarlyView.Abstract Understanding unsteady flow regimes in river channels downstream of a reservoir, is essential for predicting and regulating water level and flow velocity in the lower basin. Using hourly observations of discharge and water level at Xiangjiaba Station from 2018 to 2022, an evaluation indicator was proposed to analyze unsteady flow regimes ...

Bath Vibration During Open Eye Formation in a Physical Model of a Steelmaking Ladle
steel research international, EarlyView.Using a physical model, this study shows that vibration measurements reliably predict open eye size in steelmaking ladles, offering a practical alternative to visual monitoring. Vessel vibrations stabilize faster than the open eye, except at high frequencies near the bottom.
