IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

A General Form of Sediment Transport Equations in Alluvial Channels
Author : Caian Huang, Chih Ted Yang and Chenjuan Jiang
So far, more than 100 sediment transport equations have been proposed by using methods of semi-theory or empirical approach, but none of these equations has been accepted as a generalized equation because their application are only limited to certain flow and sediment conditions. Selecting an a ppropriate flow intensity parameter is a fundamental problem to construct a sediment transport equation. After analyzing various measures of flow intensity such as shear stress, velocity, and stream power, it is found that flow intensity can be expressed as a unified form which can summarize various existing flow intensity. Based on this unified flow intensity, a generalized sediment transport formula is derived. It is presented that many of the previous formulas are only some special cases of the present generalized formula when the coefficient and exponents take certain values. More researches are needed in determination the constant and exponents in the generalized sediment transport formula.
