Channel-changing Processes on the Santa Cruz River, Pima County, Arizona, 1936-86
Lateral channel change on the mainly ephemeral Santa Cruz River, Pima County, Arizona, causes damage and has spawned costly efforts to control bank erosion. Aerial photographs, historical...

Recurrence of Debris Flows on an Alluvial Fan in Central Utah
In the spring of 1983 a large debris flow occurred in the drainage of Birch Creek, near Fountain Green in central Utah. During the debris-flow activity, a new channel was incised into...

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...

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...

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...

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...

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...

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...

Status and New Capabilities of Computer Program HEC-6: Scour and Deposition in Rivers and Reservoirs
Last year the Hydrologic Engineering Center (HEC) and the Waterways Experiment Center (WES) incorporated the results from more than ten years of research and development into a new version...

Physical Forces Generated by Barge-Tow Traffic Within a Navigable Waterway
Movement of navigation traffic such as barge tows within a restricted inland waterway such as the Illinois, Mississippi, or Ohio Rivers can and will alter the flow field in and around...

Flow Field Near an Inland Navigation Tow
As a vessel moves through a body of water, disturbances are created in the form of altered water levels such as waves or drawdown and altered flow fields such as increased velocities and...

Data Acquisition for Determining the Physical Impacts of Navigation
Research is being conducted to determine the physical effects of navigation on the Upper Mississippi River System (UMRS). Extensive field data on various aspects of physical effects of...

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...

Physical Model Study of Navigation Conditions
This paper describes a physical model study performed to assess the impact of increased flows from a redeveloped hydroelectric generating station on the ability of pleasure boats to navigate...

The Development of a Plan of Study to Evaluate the Physical and Biological Effects of Increased Navigation Traffic on the Mississippi River
An integrity team prepared a Plan of study (POS) that represents the first comprehensive effort on the Upper Mississippi River (UMR), to identify and quantify impacts associated with commercial...
