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...
Data Acquisition Techniques for Rotating Machinery
Monitoring the condition and performance of a hydraulic turbine or pump requires the simultaneous collection of data related to shaft speed, torque, power, water and airborne sound pressure...
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...
Application of a Geographic Information System to Estuarine Hydrodynamic Modeling
A geographic information system has been used in a hydrodynamic study of Albemarle Sound, North Carolina, to provide an efficient means for spatial data organization, information display,...
Data Acquisition for Hydrologic GIS
Various data acquisition options for hydrologic oriented GIS are presented. These options include manual digitizing, commercial digital data, satellite products, and automated scanning....
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...
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...
Who Pays for the Unexpected in Construction: The Geotechnical Contractor's Point of View
Unexpected conditions are inherent in most construction projects and often lead to claims and legal action. Contract risk avoidance language force owners, engineers and contractors to...
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...
Geotechnical and Construction Aspects of the Immersed Tube Tunnel in Boston Harbor
An immersed tube tunnel (ITT) approximately 3,850 feet in length will be constructed as a part of the Central Artery/Tunnel Interstate Highway Project located in Boston, Massachusetts....
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...
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...
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,
