A Study on the Maximum Scour Depth of River-Crossing Tunnels

Water
As urbanization progresses and city populations grow, river-crossing tunnels assume a crucial role in transportation networks, with the maximum scour depth constituting a critical parameter influencing tunnel safety. Using Line 6 of the Nanning Metro in Guangxi, China as a case study, a two-dimensional hydrosediment mathematical model was employed to ...

FLOW-3D MODELLING OF THE DEBRIS EFFECT ON MAXIMUM SCOUR HOLE DEPTH AT BRIDGE PIERS [PDF]

38th IAHR World Congress - "Water: Connecting the World", 2019
Bridge foundations are frequently inserted in riverbeds constituted by alluvial material, being, therefore, subjected to scouring processes. Such phenomenon is aggravated during flood events due to the increase of water flow or due to the increase of the debris carried by the flow that can pile up along the bridge structural elements.

Interaction of Bridge Pier and Abutment on Local Scour Around Them [PDF]

علوم و مهندسی آبیاری, 2016
The local scour around bridge pier and abutment in recent years has been widely studied by different authors. Scant information exists as to how bridge pier proximity to abutment affects scour depth at an abutment and at a pier. Due to the fact that many

Influence Mechanisms of Spatial Optimization of the “Terraced Fields‐Gully Land Reclamation Project (GLRP)” Cascades on Erosion‐Transportation Processes in Watershed in the Loess Hilly‐Gully Region of China

Land Degradation &Development, EarlyView.
ABSTRACT Terraced fields and the Gully Land Reclamation Project (GLRP) are important soil and water conservation measures, widely constructed in China's Loess Plateau and other ecologically fragile areas in the world. However, under large‐scale governance scenarios, the impacts of the “terraced fields‐GLRP” cascade system on water and sediment ...

Experimental Scours by Impinging Twin-Propeller Jets at Quay Wall

Journal of Marine Science and Engineering, 2020
Experiments were conducted to investigate the seabed scour holes due to the interaction between the twin-propeller jet and quay wall. Vertical quay wall was modelled by using a polyvinyl chloride (PVC) plastic plate in a water tank.

Assessing Soil Erosion in a Typical Karst Region: A Model Improved by Bedrock Exposure Rate in Guizhou Province

Land Degradation &Development, EarlyView.
ABSTRACT Soil erosion is a major environmental challenge in karst regions of Southwest China, where thin soils and high bedrock exposure accelerate land degradation. This study modified the RUSLE model by incorporating bedrock exposure rate to improve erosion simulation in Guizhou Province from 2000 to 2024.
