Dispersal of Dredged Material Disposal Plumes
An empirical model describes dispersal of dredged material disposal plumes in an urban estuary, Central Long Island Sound, during spring of 1983. The model uses in situ current meter data...
Estimation of Navigation-Dam Discharge in Illinois
Techniques were used to estimate discharge for the Brandon Road Dam on the Des Plaines River and the Dresden Island, Marseilles, and Starved Rock Dams on the Illinois River in northern...
Discharge and Depth Behind a Partially Breached Dam
The role that the velocity-distribution correction factor plays in the determination of the flood discharge and corresponding flow depth behind a partially breached dam is investigated....
Reinforcement of Steep Grassed Waterways
A collaborative research program has been undertaken in the UK to develop guidelines for the use of various proprietary reinforcement systems to enhance the erosion resistance of grass...
Modelmania
The idea that model testing could be useful in planning for the control of water in rivers and other waterways received little support in this country until John R. Freeman's...
River Wave Response to the Friction-Inertia Balance
The changing character of the solution of the Saint-Venant equations for river flow problems with the dimensionless parameter F//I reflects a changing balance between friction and inertia....
Modeling Unsteady One Dimensional Open Channel Flow Using the Slope Friction Form of the Saint-Venant Equations
The flow of water in open channels has been an important research topic for many years. In 1871, B. De. Saint-Venant published a set of equations that attempted to quantify the physical...
Magnitude and Frequency Analysis in Large Rivers
A study of the magnitude and frequency of sediment transport was conducted on the Mississippi River at Natchez, MS, Red River at Alexandria, LA, and Pearl River at Bogalusa, LA. The individual...
Segregation of Sediment During Deposition
A laboratory experiment was conducted to investigate the segregation of sediment during deposition. Sediment eroded from an upslope source area of Blount silt loam was introduced to a...
Composite Resistance to Flow With an Ice Cover
Recent data collected on several rivers in Michigan suggest, with only an ice cover present, that Manning's roughness ratio is constant at n//R equals 0. 65. If other ice...
Alternative Methods for Representing Sinkholes in Three-Dimensional Ground Water Flow Models
Two methods of representing the sinkholes in central Florida were investigated with a three-dimensional finite element model recently developed by Camp Dresser & McKee Inc. Both...
Ground Water Flow Simulation in a Small Drainage Basin
This paper describes the development and use of a numerical simulation approach for predicting ground water flow in a small drainage basin in southern California. The purpose of the modeling...
An Analysis of Channel Stability of the Red River from Shreveport, Louisiana to Index, Arkansas
To analyze the stability of the Red River in the study reach (Shreveport, LA to Index, AR) two comprehensive hydrographic surveys were studied. The hydrographic surveys were compared to...
Flood-Control Channel Stability Assessment
Guidelines for conducting a stability assessment of a channel proposed to be modified for flood control are presented in this paper. The basis behind this assessment is that a channel...
Mathematical and Laboratory Modeling of Transport in Partially Saturated Soils
The salient features of a two dimensional flow and solute transport model in partially saturated soils are presented. A Galerkin finite element approach for the numerical solution of the...
Two-Dimensional Groundwater Transport Subgrids in a 3-D Flow Model
The USGS Modular 3-D Finite Difference Ground-Water Flow Model by McDonald and Harbaugh (MODULAR) simulates ground-water flow in three dimensions by breaking the modeled region into several...
On the Selection of Sediment Transport Equations
Existing sediment transport relationships have been calibrated under a certain range of experimental conditions which can be described by the dimensionless grain size, the mobility number,...
Effect of Streamflow Conditions on Gas-Transfer Coefficients
Contrary to the findings of previous studies of channel-controlled stream reaches, it was found that, in four reaches of a small stream characterized by a series of pools and riffles,...
Response of a Lake Outlet Channel to Dredging
Channel improvements were completed in 1982 along approximately 8 miles of the Little Tallahatchie River just downstream of Sardis Dam. Heavy rains shortly after completion of the improvement...
Contaminant Transport from an Array of Sources
The authors show analytic solutions to the problem of contaminant dispersion from an array of point sources in a waste disposal site. These solutions are for waste sources in a fluid-saturated...
