Model Studies on Local Scour

1984
The problem of local scour appears deceptively simple at the first sight, but continues to defy attempts of a rational solution. Due to the complex nature of the problem and a large number of variables involved a purely theoretical approach has been extremely difficult.

Local Scour Downstream of Hydraulic Structures

Journal of Hydraulic Engineering, 1995
An analysis of the problem of local scour downstream of hydraulic structures is presented here. This paper briefly discusses the functional design of the bed protection downstream of large hydraulic structures. Phases of the scour process and transport mechanism are treated in an introductory manner.

Overlooked Local Sediment Scour Mechanism

Transportation Research Record: Journal of the Transportation Research Board, 2004
A heretofore overlooked mechanism is described for the removal of sediment in the vicinity of a structure, such as a bridge pier, located in erodible sediment and subjected to water flow. The strength of this mechanism depends on, among other things, the ratio of structure width to sediment grain size, b/D 50

Local Scour by Turbulent Jets

2004
The present study investigates with laboratory experiments the scour downstream of a sill, followed by a rigid apron, in clear water scour conditions. Nine experiments were run, changing the discharge and the tailwater depth of the flow. The temporal evolution of the scour was recorded by a video camera and measured using image analysis techniques.

Local scour and scouring tests in a vicinity of large diameter offshore caisson

This paper describes the results of the model tests of sea bottom scouring in the vicinity of large diameter cylindrical offshore structures. The main goal of this investigation was two fold: firstly to study the sea bottom scouring around large, caisson type platforms in the arctic shallow water regions and secondly to find the suitable scouring ...
