Estimating Sediment Delivery and Yield on Alluvial Fans
This paper summarizes the procedures used for computing the basinwide annual yields and single event sediment production for ephemeral channels located on an incised alluvial fan in Central...

Sediment Sources, Transport and Delivery to an Alluvial Fan, Caliente Creek, California
Sediment delivery to a proposed flood detention reservoir site in the medial region of the Caliente Creek alluvial fan is dependant on the magnitude and duration of flood flows. Because...

Complex Geomorphic Response to Minor Climate Changes, San Diego County, CA
Precipitation in San Diego County, California over the past several hundred years has been characterized by excursions between periods of relatively low precipitation having durations...

Flood Control Improvements on Alluvial Fans
Floodplain management on alluvial fans has become an increasingly important issue with continued growth and urbanization in the southwest. The design of flood control facilities for new...

Flow Distribution in Multiple Channels with Partial Ice Coverage
It is not uncommon for rivers to have multiple channels. The distribution of the total flow to the individual channels depends on their relative hydraulic characteristics of depth, width...

Development of Suspended Sediment Concentration Profiles
This paper deals with the adjustment of suspended sediment concentration profiles in a fully developed, steady, uniform two-dimensional turbulent open channel flow without initial sediment...

Example of the Stable Channel Design Approach
This paper shows an example application of a new method being packaged by the US Army Engineer Waterways Experiment Station to aid in the design of stable flood-control channels. A stable...

Environmental Design of Channels?Can It Be Done?
The importance of environmental features to channel design is generally accepted and procedures for incorporating environmental features into flood control channel design have been developed....

Identification Techniques for Bank Erosion and Failure Processes
The Hydraulics Laboratory of the US Army Engineer Waterways Experiment Station (WES) has developed techniques to design small flood-control channels. A component of this research is the...

Guidance on the Selection and Use of Sediment Discharge Formulas
The purpose of this paper is to discuss the sediment function module of the computer program SAM. SAM is being developed as a product of the US Army Corps of Engineers Flood Control Channels...

Channel Network Analysis Using Simultaneous Solution Algorithm
In this paper, a simultaneous solution algorithm for one dimensional unsteady flow routing through channel networks is introduced. This direct solution algorithm is based on the double...

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...
