Local Scour and Sediment Deposition at Bridge Piers during Floods
(2020)
The local scour and sediment deposition at a bridge pier during flood waves is analyzed to investigate the effects of different flow and sediment regimes (regulated and unregulated discharges with or without excess sediment ...
Socavación local y sedimentación alrededor de cepas de puente durante crecidas = Local Scour and Deposition at Bridge Piers during Floods
(Universidad de Concepción.Departamento de Ingeniería CivilDepartamento de Ingeniería Civil., 2018)
A better understanding of the bridge pier scour caused by flood waves is expected to allow a different design approach based on the expected scour depth caused by one hydrological event in combination with appropriate ...
Scour around bridge piers in fluvial sediments.
(Universidad de Concepción.Departamento de Ingeniería CivilDepartamento de Ingeniería Civil., 2013)
Scour at piers embedded in a bed of cohesive sediment mixture was investigated to quantify the effects of bed compaction. Experiments were conducted in a large rectangular laboratory flume, with natural clay sediment ...
Estimación de la profundidad de socavación local bajo condiciones hidraúlicas impermanentes Effective flow work for estimation of pier scour under flood waves
(Universidad de Concepción.Departamento de Ingeniería CivilDepartamento de Ingeniería Civil., 2015)
Bridges are important for society, especially for the mobility, economy and development of humanity. The main objectives for the design of bridges are linked to life expectancy, stability, and safety during natural extreme ...
A model for local scour during flood waves = Un modelo para socavación local durante crecidas.
(Universidad de Concepción.Departamento de Ingeniería CivilDepartamento de Ingeniería Civil., 2016)
The local scour during flood waves is the main cause of bridge collapses all over the world so its study and modeling is of great interest. However, the scour caused by flood waves has been scarcely investigated. The reason ...

Dimensionless Effective Flow Work For Estimation Of Pier Scour Caused By Flood Waves
(2017)
The pier scour caused by flood waves is analyzed, introducing the dimensionless effective work by the flow on the sediment bed around the pier, W*. The three-parameter exponential function is adopted to relate the normalized ...
Physical scale modelling of scour around bridge piers
(2019)
The feasibility of physical modelling techniques for quantification of prototype bridge pier scour in reduced scale models is investigated through 17 ad hoc designed experiments which were conducted in three flumes with ...
