Sediment Modeling of Dam Removal Alternatives, Elwha River, Washington
The new version of the U.S. Army Corps of Engineers (ACOE) 1-Dimensional sediment transport model, HEC-6 'Scour and Deposition in Rivers and Reservoirs', was...

Sediment Problems Associated with Dam Removal, Muskegon River, Michigan
This paper presents an analysis of sediment movement in Michigan's Muskegon River following the removal of Newaygo Dam. The analysis utilized a physical process simulation...

Predicted Fluvial Response to Dam Removal in the Kalamazoo River Valley, Michigan
Research has been conducted by the Michigan Department of Natural Resources (MDNR) to predict the fluvial response to dam drawdown and determine the distribution of recent deposits along...

Measurement of Air Entrained Flow Properties
The paper discusses conventional methods used in the field to measure bubble size, air concentration, intermittency, and velocity of air entrained flows in chutes....

Ultrasonic Velocity Meter Used in Stream Gaging
Many streams and canals in Florida are affected by tides or control structures and experience very low flow velocities at times. For example, the St. Johns River in northeastern Florida...

McClure Park: A Multi-Purpose Off-Stream Storage Facility for Tulsa, Oklahoma
The City of Tulsa is in the process of implementing a flood control plan for the 61 square-mile (158 km2) Mingo Creek watershed. The federally-assisted...

Field Measurement of Hydrodynamics and Sediment Transport of the Mississippi River at Old River
Two detailed field surveys of the hydrodynamics and suspended sediment transport of the Mississippi River at the Old River Control Structure complex were completed in February and June...

Sediment Sources Analysis for Peoria Lake Along the Illinois River
The modern-day lower Illinois River flows within a greatly oversized valley formed by an old course of the Mississippi River and glacial outwash events. As a result, the section of the...

Ambient Suspended Sediment Concentration and Turbidity Levels
The temporal variation of suspended sediment concentration and turbidity is an important component of the riverine environment. The maximum rate of discrete volumetric sample collection...

Two-Dimensional Hydrodynamic Modeling of a Reach of the Mississippi River in Pool 19
A depth-integrated finite-element model (RMA-2V) was applied on a section of the Upper Mississippi River to study the hydraulic characteristics of the floodplain-river system. The area...

A Knowledge-Based System for the Environmental Design of Waterways (ENDOW)
Knowledge-based software systems accept problem descriptions from users and apply logic in order to generate a solution or solution set. These systems function over very narrow problem...

Modeling of Dispersion in Natural Streams with Pools and Riffles
The non-Fickian nature of the dispersion process in natural channels with pools and riffles has been investigated through both laboratory experiments and the numerical solution of a proposed...

Natural Salt Pollution in the Brazos River Basin
Water quality in several major river basins in the Southwestern United States is seriously degraded by natural salt contamination. The salt originates from geologic formations underlying...

Coastal Watershed Unit Hydrographs and Methods
The results of a study to determine unit hydrograph peak rate factors for South Carolina coastal watersheds are summarized and compared with traditional values. An extension to the SCS...

Daily Drought Monitoring by the Use of Existing Hydrologic Records
To manage water efficiently in case of drought, an effective drought monitoring method has been of interest. Drought durations and their conditional probabilities are estimated by applying...

Sedimentation Aspects of Floodplain Management
This paper presents sedimentation aspects of a recent disastrous flood that occurred during September 10-12 1990 in the Han River basin, a central part of the Korean peninsula. The flood...

Calibration of Beni-Mazar Movable Bed Model
A sand-bed model representing a reach of the Nile River was constructed to study alternative solutions to maintaining the navigation channel. Flume tests were carried out first to determine...

Drought-related West Tennessee Channel Bank Failures
Massive bank failures occurred in 1988 along a 14-kilometer reach of the lower Obion River channel in Dyer County, West Tennessee where the river flows through an abandoned Mississippi...

Introduction to Immersed Tube Tunneling Symposium
Today's Symposium on Immersed Tube Tunneling is a continuation of a series of papers that began at Construction Congress '89 with discussion of mined tunnel subaqueous...

A Gas Chromatographic Protocol for the Measurement of Krypton Gas in Water
This paper presents the results of a study to investigate the feasibility of using a gas chromatographic (GC) technique for the measurement of non-radioactive krypton gas concentrations...
