Seepage is one of the important factors involved in natural flow conditions, contributing to changes turbulence patterns and morphological due transport sediments. This sediment particles influences development fluvial bedforms any river channel. However, previous research on dynamics has not considered influence seepage field over bedforms. The present experimental aims explore behavioral turb...

The reported study examines the dynamics of entrainment and its effects on the evolution of the dry atmospheric convective boundary layer (CBL) when wind shear is present. The sheared CBL can be studied by means of direct measurements in the atmosphere, laboratory studies, and numerical techniques. The advantages and disadvantages of each technique are discussed in the present paper, which also...

Installation of baffles intended to improve fish passage through culverts can reduce discharge capacity and trap debris, increasing flood risk. A sloping upstream face may reduce this risk, but new designs must be tested for fish passage efficiency. The European eel (Anguilla anguilla) is a critically endangered species, yet the suitability of even common baffle types to aid upstream movement h...

Background Three-dimensional Phase Contrast (PC) MRI has emerged as a promising non-invasive acquisition technique for assessing velocity vector fields of blood flow [1]. To address the limited sensitivity when velocities are much lower than the encoding velocity venc, three-point acquisition methods with a high venc and a low venc acquisition to unwrap the low venc scan may be employed [2]. Ho...

Abstract To investigate the relationship among summer atmospheric boundary layer (ABL) over Taklimakan Desert (TD), its land surface parameters and large scale meteorological field, Urumqi Institute of Meteorology China Meteorological Administration conducted a comprehensive observation in Tazhong, hinterland TD from July 1 to 31, 2016. The correlations between ABL height sensible heat, latent ...

Increased knowledge about energy dissipation processes around colliding ice floes is important for improved understanding of atmosphere-ice-ocean transfer, wave propagation through sea ice, and the polar climates. The aim this study to obtain such information by investigating floe dynamics in a large-scale experiment directly measuring quantifying turbulent kinetic (TKE). field work was carried...

Statistical relations used for estimating the dissipation rate of turbulent kinetic energy (TKE) in isotropic turbulence from inertial subrange Lagrangian temporal and spatial structure functions are extended here to case more realistic spectra that include low-frequency low-wavenumber ranges. It is shown using traditional based only on substantially underestimates dissipation. The improved bet...

Abstract. Trajectory models are intuitive tools for airflow studies. But in general, they limited to non-turbulent, i.e. laminar flow, conditions. Therefore, trajectory not particularly suitable investigating within the turbulent atmospheric boundary layer. To overcome this, a common approach is handling uncertainty as random deviation from mean path order create statistic of possible solutions...
