Megaproject Monitoring by Satellite ? InSAR-based Settlement-time History: Measuring Hundreds of Thousands of Points, Several Times a Month, Across an Entire City
Satellite-based interferometric synthetic aperture radar, or InSAR, has gained unequivocal importance as a routine and precise monitoring method for large and small areas alike. Historical datasets allow...

Practical Applications of Gage-Adjusted Radar?Rainfall Estimates
(no paper) It is radar's estimates of rainfall at a specific location that tends to disappoint. On the other hand, the strength of rain gage observations is in estimating rainfall at a...

Predicting with Precision
In many urban areas flood prediction systems are inadequate. Most rely on networks of widely dispersed rain gauges that often fail to provide sufficient geographic coverage to characterize...

Probing Pipelines (available only in Geoenvironmental Special Issue)
Inspecting underground pipelines has become easier, more effective and less intrusive through use of sonar, radar, lasers and seismic and acoustic testing. To replace simple visual inspection,...

Cure for Thinning Concrete
After placing 75% of the concrete liner for twin 4.6 km transit tunnels in Portland, Ore., engineers discovered areas of concrete that were thinner than the prescribed 305 mm thickness....

Indianapolis Uses New Radar Technology to Refine Hyetographs for CSO Model and SSES Studies
Indianapolis is the first city in the country to install the French-developed technology designed by urban hydrologists to accurately measure rainfall between rain gauges. Installed in...

The Timberlake Dam Failure: A Hydrometeorological Assessment
Extremely heavy rainfall over the Timberlake basin in southwest Virginia on 23 June 1995 caused an earthen dam to fail and resulted in fatalities. The meteorological conditions are examined...

Developing Parameters for a Quasi-Distributed Runoff Model Using GIS
The widespread availability of radar precipitation data is driving rainfall-runoff modeling from lumped-input to distributed-input methods. As a consequence, model parameterization is...

Spatial Statistics for Rainfall Forecasts Assessment
Assessments of rainfall forecasts were developed using GIS-based spatial statistical procedures applied to calibrated radar-rainfall fields in central Oklahoma. The overall objective of...

Conceptual Design of a Monitoring System for Maglev Guideways
The state-of-the-art in nondestructive testing (NDT) technology has advanced significantly over the past fifteen years and has reached a stage where continuous monitoring of structures...

Highway Speed Radar for Pavement and Bridge Deck Evaluation
Radar has been developed as an economical alternative evaluating pavement layer properties and estimating quantities of deterioration in bridge decks. These highway applications are based...

Exploration of Ground Penetrating Radar for Railroad Tie Maintenance Scheduling
Assessment of railroad ties for replacement is currently performed by visual inspection. This paper describes a method of automated tie assessment using ground penetrating radar (GPR)...

Mean Areal Precipitation Estimation Using Radar
The accuracy of mean areal total storm precipitation (MAP) over small urban basins (30-100 km2) in the Denver, CO metro region was examined using...

WSR-88D Precipitation Processing and Its Use in National Weather Service Hydrologic Forecasting
The National Weather Service (NWS), along with the Department of Defense and Transportation, have begun deployment of a new national network of weather radars referred to as the WSR-88D....

Scour Inspection Using Ground Penetrating Radar
This paper examines the capabilities of Ground Penetrating Radar (GPR) for river bed scour inspection based on a study carried out by Clarkson University, Potsdam, New York in association...

Evaluation of Historical Scour at Selected Stream Crossings in Indiana
Geophysical data were collected by means of ground-penetrating radar and tuned transducer systems to estimate the historical scour at ten bridges in Indiana. These geophysical data were...

Using Neural Network to Identify Pavement Structure Based on Radar Output
Knowledge of asphaltic layer thickness and structure are important in many areas of pavement management. Accurate thickness and structure measurements are needed throughout the roadway...

Application of Radar Imaging Techniques to Concrete
Wideband radar imaging techniques have the potential of being a powerful tool in detecting steel reinforcing bars and delaminations inside concrete. The success of the method as a nondestructive...

Ground Penetrating Radar: Images of Subsurface Characteristics
Ground penetrating radar has not been widely used for subsurface exploration in Civil Engineering. This paper describes the experimental setup used to explore ground penetrating radar...

Non-Destructive Remote Sensing of Hazardous Waste Sites
This paper describes how the non-contact, nondestructive, remote sensing techniques, of Computer Enhanced Infrared Thermography and Ground Penetrating Radar, may be used to detect buried...
