Effect of Bridge Pier Shape on Depth of Scour

IOP Conference Series: Materials Science and Engineering, 2020
Abstract Scour at bridge piers is a common problem in infrastructure engineering, as local scour around bridge piers is one of the most common causes of bridge failure. Prediction of the maximum depth of local scour thus plays an important role in ensuring safety and economy during design and maintenance.

7000 Years of Aboriginal Mining at Sugarloaf Hill in the Riverland Region of South Australia

Archaeology in Oceania, EarlyView.
ABSTRACT Silcrete and chert are commonly represented in Aboriginal archaeological lithic assemblages across large parts of the southwestern Murray‐Darling Basin (MDB). In South Australia (SA), these materials were sourced from a series of quarries located along the incised course of the Murray River through the upper Riverland region.

Clear-Water Experimental Scour Depths At Abutments

, 2018
Abstract—Laboratory experiments on local scour process at wing wall bridge abutments were conducted for different hydraulic conditions and compared with measurements on local scour depths around vertical wall abutments, under the same flow and sediment transport conditions.

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 ...

Effect of trapezoidal collars as a scour countermeasure around wing-wall abutments

Water Science and Engineering, 2018
Local scour around bridge abutments is a widespread problem that can result in structural failure. Collars can be used as a countermeasure to reduce the scour depth.

Partners or passengers? Revisiting the association between diatoms and aquatic animals

Biological Reviews, EarlyView.
ABSTRACT Numerous studies have revealed the importance of research on the communities capable of colonizing animal surfaces (epibionts) and the animals on which they live (basibionts). Very few studies have considered epizoic diatoms, and there are gaps and biases in our knowledge, including the choice of basibionts, the methods used, and the habitats ...

Reducing Scour around Semi-Elliptical Bridge Abutments: Application of Roughness Elements

Fluids, 2023
Bridge abutments in river channels induce local scour. Recent research indicates that introducing roughness elements on the surface of the bridge abutments can influence the flow pattern around the abutment, reducing the intensity of eddies and diverting

A Green Consumer‐Based Approach to Advance Branding Strategies in Experiential Consumption Contexts. Insight From the Cruise Industry

Business Strategy and the Environment, EarlyView.
ABSTRACT Growing environmental awareness has intensified demand for sustainability and transparency, especially in cruise tourism, a high‐impact and highly scrutinised service context. This study examines how green consumption values (GCV) shape passengers' perceptions of the credibility of green marketing claims (believability) and, in turn, influence
