Abstract: The basic assumptions used in the derivation of bedload or gravel transport equations are reviewed and examined to determine their validities. Laboratory data indicate that unit stream power is more desirable than other ...

Abstract: Hydrodynamic and hydraulic theories have been developed along two parallel approaches, i.e., the vectorial and variational approaches. Most classical hydraulic theories are based on vectorial approaches. The variational ...

Abstract: A computer model based on both the energy and momentum equations is developed. This generalized model can be used for the computation of water surface profiles through hydraulic jumps. It also allows computation of water ...

Abstract: Comparisons are made of the overall accuracy as well as the accuracy within different ranges of sediment concentration, Froude number, and slope for seven bed‐material load formulas. Four formulas that can compute bed‐material ...

Abstract: It has been the conventional assumption that wash load is supply limited and is only indirectly related to the hydraulics of a river. Hydraulic engineers also assumed that bed-material load concentration is independent of ...

Abstract: Yang's unit stream power formula is modified for the computation of total bed-material load in a sediment-laden river with a high concentration of fine suspended materials. Theoretical and laboratory studies indicate that ...
