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

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 ...

Influence of flow unsteadiness on local scour at bridge piers: An energy-based perspective

International Journal of Sediment Research
Local scour at piers is a major cause of bridge failures worldwide. While most existing studies assume steady flow conditions, actual flood events are inherently unsteady, with distinct rising and falling limbs that significantly modify scour dynamics ...

Long-term scouring effects on the lateral loading behaviour of monopiles using field monitoring data and finite element modelling

Applied Ocean Research
Scour of the seabed induced by currents and waves poses a critical threat to the serviceability and lifespan of offshore wind turbines. Despite its significance, the mechanisms and temporal evolution of offshore scour remain insufficiently understood ...

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
