An Entity of Type: Magnitude105090441, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

The Shields parameter, also called the Shields criterion or Shields number, is a nondimensional number used to calculate the initiation of motion of sediment in a fluid flow. It is a nondimensionalization of a shear stress, and is typically denoted or . This parameter has been developed by Albert F. Shields, and is called later Shields parameter. The Shields parameter is the main parameter of the Shields formula. It is given by: where:

dbo:abstract
  • The Shields parameter, also called the Shields criterion or Shields number, is a nondimensional number used to calculate the initiation of motion of sediment in a fluid flow. It is a nondimensionalization of a shear stress, and is typically denoted or . This parameter has been developed by Albert F. Shields, and is called later Shields parameter. The Shields parameter is the main parameter of the Shields formula. It is given by: where: * is a dimensional shear stress; * is the density of the sediment; * is the density of the fluid; * is acceleration due to gravity; * is a characteristic particle diameter of the sediment.
