Tag: Bridge scour
The scour at bridge foundations caused by supercritical flows is reviewed and knowledge gaps are analyzed focusing on the flow and scour patterns, on available measuring techniques for laboratory and field, and on physical and…
[2020-23] Coordinatore locale del progetto intitolato “La mitigazione del rischio idraulico in bacini costieri con casse di espansione in linea: approccio di dimensionamento integrato” finanziato dal Ministero dell’Ambiente e della Tutela del Territorio e del…
Based on recent contributions regarding the treatment of unsteady hydraulic conditions in the state-of-the-art scour literature, theoretically derived probability distribution of bridge scour is introduced. The model has been derived assuming a rectangular hydrograph shape…
The goal of this paper is to introduce the first clear-water scour model based on both the informational entropy concept and the principle of maximum entropy, showing that a variational approach is ideal for describing…
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…
The time-dependent bridge pier scour during flood waves is analysed. Scour experiments were conducted in a novel installation able to produce complex hydrographs with high precision. Experimental data were used to test scour formulas including…
