Turbulence and Reynolds Stress Distribution in a Natural River
Turbulence characteristics of ambient flow velocities and their comparison with those generated by the movement of barge traffic within the channel border area in a navigation waterway...

Uncertainty Quantification in Water Distribution Parameter Estimation
Calibration for water distribution system model parameters is usually undertaken with a minimal amount of field measurements so additional pseudomeasurements are assumed. Both the actual...

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...

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...

Fluvial Recharge of Sand Mining Pit
Accuracy in modeling fluvial processes becomes increasingly important as development occurs along waterways. The FLUVIAL-12 (1, 2) model is used to simulate the recharge of sand mining...

Development of Crop Coefficients Using Lysimeters
A long term record of evapotranspiration by grass as measured with the large weighing lysimeter at the University of California at Davis provided an excellent background for the initiation...

Construction Product Performance, The Unexpected
Efforts made in the construction, industry to increase the quality of the constructed facility through the development of new materials and systems and through the reduction of labor intensive...

Computer Assisted Design and Construction
This paper presents a comprehensive package for conducting structural analysis, design, and project management on microcomputers. Several examples are presented to illustrate the usefulness...

Reasoning for Data Integration
Improving the inter-disciplinary communication of design and construction data is an important objective in improving the competitiveness of our construction industry. This paper discusses...

Site Layout: Where Should it Go?
Site layout is mostly treated as a task independent of other resource allocation tasks such as those that are traditionally associated with construction planning and scheduling. Yet, the...

Smart Exception Reporting
Project control systems that contain a degree of 'intelligence' are possible with today's technologies. At the same time project controls engineers...

Integrated Cost and Schedule Control Automation
Effective management of construction projects depends on good access to and control of data, especially data pertaining to cost and schedule control functions. Long recognizing the need...

Kinematics and Trajectory Planning for Robotic Excavation
One of the high volume and repetitive construction operations at the construction site is the excavation of soil. Automation of the excavation work requires a robotic system that is able...

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...

Characteristics of Low-Slope Streams that Affect O2 Transfer Rates
Multiple-regression techniques were used to derive the reaeration coefficients estimating equation for low sloped streams: K2 = 3.83 MBAS-0.41...

A Simple Empirical Model of Aeration at Navigation Dams
In a study of aeration at 28 dams in the upper Ohio River basin, site-specific least-squares linear regression models were used to describe the dissolved oxygen deficit below each dam...

Lysimeters for Evapotranspiration and Environmental Measurements
Lysimeters have been used extensively in the past to provide baseline information for development, calibration, and validation of evapotranspiration methods. This proceedings, Lysimeters...

Instrumentation for SASW Testing
The Spectral-Analysis-of-Surface-Waves (SASW) method is presented. Various test setups and corresponding data reduction procedures are discussed. Several instrumentation systems have been...

Accuracy and Resolution of Surface Wave Inversion
Shear wave velocity profiles of soils and pavements may be evaluated nondestructively using surface wave tests such as the Spectral Analysis of Surface Waves (SASW) method. In these tests,...
