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...

A Review of the State-of-the-Art in Sediment-Water Column Interaction Measurement Techniques
This paper reviews the state-of-the-art measurement techniques available to water quality modeling practioners to estimate: (a) sediment oxygen demand rates, (b) sediment-water column...

The Effect of Grain Size Distribution on the Entrainment of Interstitial Water into Overland Flow
Non-point source pollution from agricultural runoff is an important environmental problem. This experimental study considers the effect of media heterogeneity on the entrainment of interstitial...

Water Supply and Aeration Demands for Shrimp Farms
A computer model was developed simulating flow and aeration requirements for a range of farm sizes, from 50 to 2000 hectares. Climatic effects and water quality upset conditions were included...

Forces Acting on a Vortex-Excited Vibrating Cylinder in Planar Oscillatory Flow
An experimental investigation into the vortex-excited vibration of a circular cylinder in planar oscillatory flow has been made with emphasis being placed on the amplification of the forces...

Modeling of Surface Vortices in Unsteady Flow
Hydraulic model studies of lock filling and emptying systems include investigating vortex tendencies at the intake vincinity during filling. The flow at the intake vicinity is unsteady...

A Branched Mass Transport Model of the Sacramento-San Joaquin Delta, California
A new branched mass (salt) transport model is used to simulate salt transport in the Sacramento-San Joaquin Delta, California. The model uses a two-step procedure to determine the salt...

CORMIX2: Expert System for Multiport Diffuser Discharges
The Cornell Mixing Zone Expert System (CORMIX) is a series of software systems for the analysis, prediction, and design of aqueous toxic or conventional pollutant discharges into watercourses,...

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...

Effect of Temperature on Settling of Fine Sediments
Results from settling experiments in an annular flume using kaolinite clay in distilled water are presented. Identical experiments carried out at different temperatures show that as temperature...

A Hybrid Model for Sediment Concentration Profiles
The paper discusses the deficiency in the existing theories on suspended concentration profiles which is due to the variations of theories for modeling the velocity profiles. As can be...

Experimental and Numerical Study of Overland Flow Induced by Rainfall on the Loess Slope
Based on the repeated experiments of overlad flow on the Loess slope under the condition of constant and variable artificial rainfall intensity in laboratory, the mathematical model corresponding...

A Fractal Concept in Stream, Swale, and Sheet Flow
The concept of fractals, in simple terms, says that the patterns of natural features repeat themselves as the feature gets divided into successively smaller segments. In this paper, the...

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...

Stable Channel Analytical Design Method
The Flood-Control Channels Research Program is being conducted at the US Army Engineer Waterways Experiment Station to develop systematic methods for design of stable channels for small...

Weibull Distribution and Natural Hydrograph
For design projects in water resources, a hydrograph is commonly used for the determination of flood volume generated by a given drainage basin. The division of total flow into direct...

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...

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...
