Modeling Erosion and Deposition Due to Suction and Jet Flows
PHOENICS, a commercial 3-D computational fluid dynamics software package, was modified for simulating seabed erosion and deposition. Time varying sediment fluidization, transport and deposition...
The Relationship of Milligrams Per Liter to Parts Per Million
Derivations of the relationships between mg/l and ppm are presented. Although forms of these relationships can be found in scattered references, the author's intent is to...
Hyperconcentrations, Mud and Debris Flows?A Summary
Brief descriptions of the properties of mud and debris flow and hyperconcentrated stream flow materials and their importance to the descriptions and modeling of these flows are presented....
Relationship Between Channel Migration and Radius of Curvature on the Red River
The system behavior of meanders was investigated on the Red River between Shreveport, LA, and Index, AR. The effects of plan form geometry (r/w) and erodibility of bank material on the...
Infiltration of Water to the Ground in a Flood-Control Reservoir with Seepage
As storm water management in urban area with increasing amount of runoff, flood-control reservoir with the bed having large permeability to enrich the groundwater is considered. A dynamical...
Cold Regions Engineering
This volume contains papers that were presented at the 5th International Cold Regions Engineering Specialty Conference, sponsored by ASCE and held in St. Paul, Minnesota, February 6-8,...
Boundary Element Methods in Structural Analysis
Tutorial and state-of-art aspects of the Boundary Element Method (BEM) are combined with applications in structural analysis in order to provide information about the advantages of this...
Numerical Model Studies of Wetland Hydraulics for Bolsa Bay, California
The Bolsa Bay area, near Los Angeles, presently consists of three distinct regions separated by two sets of culverts. A development is being considered, in which a balance between housing...
The Turbulent Wake of a Recirculating Eddy in Shallow Waters
The wake, created by injecting dye into the recirculating zone of a sudden lateral expansion in a shallow open channel, is examined experimentally for a range of bed-friction influence....
Cellular Automaton Simulation of Viscous Free Surface Fluid Dynamics
It has been demonstrated elsewhere that the simple interaction of a two dimensional field of discrete particles traveling on a regular lattice yields large scale behavior closely approximating...
Analysis of Storm Sewers During Surcharge
A mathematical model based on a lumped system approach is presented to simulate unsteady flow in storm sewers during surcharge. The model equations and method of solution are presented....
An Ongoing Investigation of Residual Suspended Material Transport in Central San Francisco Bay, CA
A study of suspended material transport in San Francisco Bay, California, is presently underway by the U.S. Army Corps of Engineers. This paper describes preliminary numerical model and...
Estimating Urban Flood-Frequency Characteristics
Methods in use by the U.S. Geological Survey to estimate flood-frequency characteristics for urban watersheds are compared with estimates based on the Soil Conservation Service TR-55 model....
Effects of Climate Change on Watershed Runoff
This paper examines forecasts of changes in watershed runoff in the Delaware River basin that result from a range of predicted effects of increased atmospheric carbon dioxide (CO2)...
Cocohatchee River Basin Study
The report presents the modeling of the Cocohatchee River basin, including 2-D routings for wetland regimes, hydrologic/hydraulic analyses of the agricultural and suburban land uses, and...
Redundancy and Reliability of Water Distribution Networks: An Entropy Based Approach
Based on the concepts of entropy and graph theory, a functional form is developed as a quantitative measure for redundancy in water distribution networks. This function was obtained by...
Conditional Simulation of the Wilmington Sand-Shale Sequence, Los Angeles Basin
In shaly clastic reservoirs at a scale where vertical cross flow cannot be ignored the main source of heterogeneity is the apparent random geometry of the sand-shale sequence. That geometry...
International Research on Mechanics of River Bank Erosion?A Summary Overview
A brief overview is presented of research regarding mechanisms of river bank erosion and treatments. In the research river planforms, water stages, currents, waves, ice sediments, bed...
Uplift Pressure below Gravity Dams on Rock
The magnitude of the uplift force at the base of a concrete gravity dam founded on rock is strongly dependent on the properties of the discontinuities within the rock mass. This paper...
Asphalt-Rubber Concrete?A New Horizon
The performance of asphalt concrete pavements is dependent to a large degree upon the rheological properties of the asphalt binder. Asphalt-rubber as a binder material extends the temperature...
