Study on Hydrologic Response Via Channel Network Geomorphology
A drainage basin consists of slopes and channels. Slopes are the main fields at which rainfall input is converted into discharge. Stream-channels are the main fields at which the discharge...

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...

Sediment Concentration Measurements Below Small Headcuts
This study is designed to determine erosion rates downstream from a small headcut. The sediment concentration from a scour hole produced by a plunging jet is measured as a function of...

Variational Method in Fluvial Hydraulics?A Review
The theoretical base of the principle of minimum energy dissipation rate and other related stationarity hypotheses have been reviewed. Recent applications of the theory to the calculation...

Introduction of Variational Principle Into Open Channel Hydrodynamics
Possible applications of the variational principle maximizing the entropy are illustrated. Open channel flow properties are expressed in terms of 'entropy parameter',...

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....

Modification to John H. Overton Lock and Dam
The Red River Waterway Project, Mississippi River to Shreveport, Louisiana, will consist of a navigation channel 9 feet (2.7m) deep by 200 feet (61.0m) wide, 5 locks and dams providing...

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...

Computational Open-Channel Hydraulics for Movable-Bed Problems
As a major branch of computational hydraulics, notable advances have been made in numerical modeling of unsteady open-channel flow since the beginning of the computer age. According to...

Urban Soft Bottom Low Flow Channel?A New Approach
In 1987, the City of Boulder, Colorado requested assistance from the Urban Drainage and Flood Control District (District) to repair an all too familiar problem of cattails growing in the...

A Multimode Scheme of Characteristic Method for Open Channel Flows
This paper deals with the stability and accuracy of a multimode scheme, based on the method of characteristics, for unsteady one-dimensional open-channels flows. This scheme combines three...

Development of a Computer Aided Decision Process for Channel Rehabilitation and Watershed Enhancement Techniques
To assist the engineer in planning and design of channel stabilization measures, an expert system (CADWET) was developed using a commercially available expert system shell program. The...

Prototype Measurements of Flows Induced by Navigation Tows
Present projections of growth of commerical navigation traffic indicate that annual tonnage per tow and/or number of tows will continue to increase through the foreseeable future. In order...

Application of Weakly Compressible Flow Method to 2-D Open Channel Flows
The depth averaged equations for open channel flows are shown to be similar to that of the weakly compressible flows. The finite volume scheme developed for weakly compressible flows has...

Low-Head Drop Structure Hazards: Modeling of an Abrupt Drop Boat Chute
Low-head drop structures are dangerous for navigational and recreational boating in rivers. In an effort to reduce drowning hazards at low-head river drop structures, a boat chute bypass,...

Hydraulic Geometry of Mississippi Hill Streams
Hydraulic geometry data based on field and office studies are presented for a series of streams in the Black Creek and Long Creek watersheds in the upland hills of Central and Northern...

Stabilization of an Alluvial Channel in an Urbanized Area
Grade stabilization structures have been used for many years to control degradation of alluvial stream in the southwest. These structures result in reducing the gradient of the stream...

Longitudinal Channel Response Due to In-Stream Mining
This paper describes the analysis procedure developed for the Arizona Department of Transportation for the estimation of short-term longitudinal channel response due to in-stream mining....
