Simulation of Channel Changes Induced by a Reservoir
A fluvial study was made for potential stream channel changes induced by a reservoir. It is generally recognized that a reservoir induces sediment deposition along the upstream channel...
Impacts of Reservoir Sedimentation on Decommissioning of Dams
A large number of dams in the United States of America and elsewhere are reaching the limits of their design lives. Owners, agencies and environmentalists are either considering or demanding...
Modeling Groundwater Contaminant by Unstructured FVM
This study focuses on the numerical solution of the integral form of transport equation on unstructured grids. The algorithm is developed in direct finite volume concept and constructed...
Discussions of a 3D Numerical Simulation of Transient Regional Groundwater Flow and Transport
A 3D numerical model of a groundwater flow and transport was developed to study the movement of radionuclides in the Savannah River Nuclear Site, South Carolina. The modeling effort has...
The Treatment Train Detention Concept
With the recent concern for nonpoint source pollution impacts to receiving waters, the Village of Saukville, Wisconsin took advantage of state funding grants to conduct a Stormwater Management...
Calibration of Sediment Transport Model for the Upper End of Elephant Butte Reservoir
Elephant Butte Reservoir is located about 125 miles north of El Paso, Texas on the Rio Grande. The reservoir is approximately 35 miles long with a narrow neck, called the Narrows, about...
Uncertainty Analysis of Reservoir Sedimentation
In estimating reservoir sedimentation, a number of uncertainties arise. These are related to annual streamfiow, sediment load, sediment particle size, trap efficiency, and reservoir operation....
Degradation of Carboxydiphenyl Ether via Bioaugmentation
Two diphenyl ether-degrading bacteria,
Sediment Removal from Stormwater Runoff
Sediment traps, also known as baffle boxes, are being used throughout the state of Florida to remove sediment from stomiwater. A baffle box is divided into three compartments by two bathers,...
Interdisciplinary Research of Mountainous Areas: Past, Present, and Future
In the past few years, there has been a growing recognition internationally, of a need to better understand hydrometeorologic, hydraulic, sedimentologic, geomorphic processes in gravel-,...
Nearshore Hydrodynamic and Water Quality Modeling for Water Intake Evaluation and Design
The nearshore water of the Great Lakes is of vital interest to millions of residents. Lake water is often the focal point in issues concerning economic development, recreation, and public...
Detailed Measurements of Scour at Bridges
The U.S. Geological Survey, in cooperation with the Federal Highway Administration, has recently developed equipment and techniques for collecting detailed bathymetric and hydraulic data...
Research to Application: Network Models to Simulate Flow and Transport in Heterogeneous Media
Effective groundwater cleanup requires accurate site-specific information on cleanup processes. Numerical simulations limit the need for expensive field experiments and provide details...
Computational Tools for Subsurface Conceptualization
Development of subsurface conceptual models for use in groundwater flow and transport modeling requires that existing data in the form of boring logs, cone penetrometer (CPT) logs, geophysical...
Water Quality Impacts of Dredging and Disposal Operations in Boston Harbor
The Massachusetts Port Authority is presently planning a navigation improvement project in the port of Boston, consisting of dredging the 10.7 m (35 ft) deep channels and berths in the...
A DEM Based Hydrologic and Sediment Transport Model
A DEM-based, physically-distributed model was developed for simulating event runoff and erosion on an agricultural watershed. Runoff was described using the diffusion equation with flow...
Stormwater Management for San Joaquin Hills Transportation Corridor, Orange County, California
San Joaquin Hifis Transportation Corridor (SJHTC or Corridor) is one of the largest design-build toll roads in U.S.A. To meet stringent environmental mitigation requirements, to ensure...
Selection of Sediment Transport Relations: Part I, Review of Sediment Transport Comparisons
There are a great number of sediment transport relations in existence in the world today. The engineer is often faced with the problem of choosing the most appropriate relation for the...
Selection of Sediment Transport Relations: Part II, Ranges of Dimensionless Numbers
With a large number of sediment transport equations claiming to be applicable within various ranges of hydraulic and sediment parameters, engineers are often faced with the dilemma of...
Selection of Sediment Transport Relations Part III: Numerical Ranking of Sediment Transport Relations
The emphasis of this paper is the methodology for the selection of sediment transport relations and is applicable for analysis of any sediment transport relation. However, to illustrate...
