Hydraulic erosion patterns downstream of corrugated aprons: investigating free and submerged jet effects

Frontiers in Environmental Engineering
The experimental evaluation of the performance of a corrugated apron under free flow subcritical and submerged conditions was conducted, with a focus on scour patterns over the apron. Comparative analysis with a smooth rigid apron revealed an increase in

Scanning Parametric Sediment Echosounder as Tool for Underwater Archaeological Prospection

Archaeological Prospection, EarlyView.
ABSTRACT Underwater cultural heritage 3D prospection techniques, especially for remains that are partly buried in the ground, are only very rarely available and often can only be applied with considerable technical effort. To overcome this limitation, we evaluate a methodological adaption of widely used and available single channel parametric sediment ...

Hydrodynamic Modeling and Comprehensive Assessment of Pier Scour Depth and Rate Induced by Wood Debris Accumulation

Hydrology
This study mainly investigates the impact of debris accumulation on scour depth and scour hole characteristics around bridge piers. Through controlled experiments with uniform sand bed material, the influence of various debris shapes (high wedge, low ...

Pattern of channel adjustment due to bottom-block scour on the Yellow River

Shui kexue jinzhan, 2015
The paper is intended to show the patterns of the changes both in the cross section and the local flow due to a peculiar kind of scour,bottom-block scour,or named as bottom tearing scour and bottom ripping up,which is often found to occur in the forms of

Arthroscopic Repair of Radial Meniscal Tear Using Fibrin Clot Augmentation and “Hashtag” Style Inside‐Out Technique

Arthroscopy Techniques, EarlyView.
Abstract Significant meniscal injuries lead to pain and possible early osteoarthritis development. Fibrin clot augmentation represents an effective, cost‐efficient method for improving healing rates in poorly vascularized meniscal tears. This arthroscopic technique shows fibrin clot augmentation combined with horizontal and vertical mattress sutures in

Atypical Predictive Processing Is Associated With Sensory Over‐Responsivity in Autism

Autism Research, EarlyView.
ABSTRACT Autism is characterized by sensory processing atypicalities including sensory over‐responsivity (SOR), a heightened negative response to sensory stimuli. Although the neural mechanisms underlying SOR are not fully understood, SOR has been associated with sensory‐limbic hyper‐reactivity during sensory stimulation.
