Effects of Fine Sediment Intrusion on Spawning Gravel in Southeast Alaska
The supply of sediment to forest streams in Southeastern Alaska is related to the inherent instabilities of landforms, stream channels and the effects of logging practices. Debris avalanches,...

Issues and Challenges Facing the Effective Delivery of Scientific Visualization
The availability of economical hardware and software products for scientific visualization has stimulated implementation of scientific visualization within high performance computing environments....

Introduction, and Analysis of Survey?Preliminary Report of Task Committee on Recommendations for Standards in Hydraulics
To help formulate its recommendations for future standardization of tasks in hydraulic engineering, the Task Committee conducted a survey of practicing engineers. This survey indicated...

Existing U.S. Standards in Hydraulic Engineering
The Task Committee on Recommendations for Standards in Hydraulics confined itself to topics that are used in hydraulic computations or design. Thus numerous standards related to size,...

Foreign Hydraulic Standards and Guidelines
Standardization in Europe is propelled by the incentive to achieve harmonization of design, testing, inspection and certification methods for an internal market among eighteen European...

Preliminary Recommendations from the Task Committee on Standards in Hydraulics
The Task Committee on Standards in Hydraulics has been given the responsibility of recommending whether or not the American Society of Civil Engineers (ASCE) should formulate standards...

Environmental and Hydraulic Considerations in the Design of a Circulating Water Cooling System
Environmental considerations play an important part in the design of a condenser cooling system. A once-through system may require assessment of a combination of events to determine the...

Set-Down in a Tidal Embayment
A mean water level in tidal bays and estuaries that is higher than the ocean mean water level (set-up) is a fairly common occurrence. Set-down of the mean water level can be shown to be...

Visualization of a Groundwater Contaminant Model
Groundwater contamination is a problem of major national concern. Three-dimensional characterization of groundwater contamination is typically required. This paper describes integration...

Visualizing Groundwater Flow
This presentation demonstrates the application of some public domain scientific visualization software tools in the area of groundwater modeling. Specifically, we use these tools to interpret...

A Three-Dimensional Natural Resource Damage Assessment and Coupled Geographical Information System
A numerical model for natural resource damage assessments is discussed. The model addresses a wide range of spatial and temporal scales. The transport equations for both pollutant and...

A New Approach to Local Scour Depth Estimation Under a Horizontal Jet or Free Water Fall
A new formula is presented to estimate the local scour depth development with time due to a horizontal jet or free water fall based on a new approach which combines the concept of energy...

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...

Data Acquisition Systems for IBM Compatible System
Portable data acquisition systems composed of IBM compatible PC/XT/AT computers and analog to digital conversion cards can be configured with relative ease. These systems have the flexibility...

Computerized Data Acquisition for an Undergraduate Hydraulics Laboratory
Basic hydraulics principles and the operation of certain hydraulic systems can be effectively demonstrated with the aid of relatively inexpensive data acquisition and analyses systems....

Use of Electronic Microprocessor-Based Instrumentation by the U.S. Geological Survey for Hydrologic Data Collection
The U.S. Geological Survey is acquiring a new generation of field computers and communications software to support hydrologic data-collection at field locations. The new computer hardware...

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...
