Stability Criteria for Revetments
A simplified 'black box' approach is presented for a number of revetment systems for banks and shore protection. The design criteria, based on the physical similarity...

The Influence of Uniformity on Riprap Stability
Studies have shown that size uniformity influences the stability of riprap. The ratio of fractional sizes of the riprap mixture, D₆₀/D₁₀,...

Riprap Stability Results from Large Test Channel
Velocity data from a large test channel were used to determine the distribution of depth-averaged velocity and shear stress on the side slope of both straight and curved channels. From...

Physical Modelling of Self Forming Alluvial Channels
A method is presented for the determination of a practicable physical model of self-forming channels in cohesionless alluvium. Both sand bed and gravel bed regime channels are considered....

Scale Effects of Overflow-Oriented Hydraulic Parameters for a High Dam
This paper presents the findings of prototype observation and model verification on the surface velocity, the range of nappe jetting, and the diffusion regime of the discharged flow related...

Characteristics of the Flood Release-Induced Vibrations with Qianshui Thin-Arch Dam
In this article the prototype observations and design analyses are described regarding the flood release-induced vibrations of the Qianshui thin-arch dam and its foundation; and their...

Application of the Generalized Channel Routing Model
Using the linear full dynamic finite difference model the applicability of diffusion and kinematic wave models is investigated. Two dimensionless numbers are suggested for applicable range...

Conservation Properties of Flow Simulation Models
The fundamental equations of fluid mechanics and hydraulics posses certain integral properties which should be maintained by their discrete analogs. In this paper the conservation properties...

The Method of Lines Solution of Unsteady Open Channel Flow Equations Along Characteristics
The method of characteristics (MOC) has long been considered as a natural procedure for solving transient flow problems. In this paper, by using the concept of the method of lines, the...

Comparison of Correction Factor for Dispersion Coefficient Based on Entropy and Logarithmic Velocity Profiles
Recently, new velocity distribution equations have been developed by Chiu (1987, 1989) through the use of maximum entropy principle. A comparison will be made of the correction factor...

Status and New Capabilities of Computer Program HEC-6: Scour and Deposition in Rivers and Reservoirs
