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.

Fire buffers drought impacts on reproduction in a resprouting Mediterranean shrub
Oikos, EarlyView.Fire and drought increasingly co‐occur, exposing plants to greater drought stress during post‐fire resprouting. Yet, the effect of this combination of disturbances on plant fitness remains poorly understood. Here, we examine how post‐fire resprouting influences reproductive success under drought conditions in the Mediterranean shrub Anthyllis ...

Modelling the effect of sediment coarseness on local scour at wide bridge piers [PDF]
, 2017 Experimental data from a physical model of scouring around a cylindrical wide pier embedded in two types of uniform sediment beds are presented. The effects of sediment sizes and various pier widths on scour development and equilibrium scour depth of ...

Oikos, EarlyView.Anthropogenic stressors often co‐occur in ecosystems, but their combined impacts are rarely assessed using field experiments. Press disturbances particularly can reshape community dynamics, altering their capacity to withstand or recover from acute pulse disturbances by modifying response diversity.

Preliminary comparison of scour depth estimation methods
, 2022 Bridge scour is a major cause of bridge collapse worldwide. Various approaches are available to estimate levels of scouring due to hydraulic loading. Such scour depth assessment methodologies typically employ a series of empirical and semi-empirical equations to estimate scour around a bridge element.

People and Nature, EarlyView.Abstract Pastoral practices remain a widespread economic activity across European mountain regions. However, the viability of this activity may be threatened by the recovery of large wild vertebrates associated with passive rewilding, leading to the so‐called human–wildlife conflicts.

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.
