FIBRADIKE, a novel distributed fiber optic monitoring system for dikes and earth dams

Paradigm Shifts in Monitoring Levees and Earthen Dams: Distributed Fiber Optic Monitoring Systems

Earthen embankments including levees, tailings dams, and earthen dams present many challenging problems for Civil Engineers, particularly in verification of their structural integrity and capacity, operation and maintenance (O&M), inspection, and safety. The sheer size and scale, age, and uncertainty of materials in these sometimes mammoth structures, all combine to present a difficult array of...

Distributed Fiber Optic Intrusion Sensor System for Monitoring Long Perimeters

Distributed Fiber Optic Intrusion Sensor System For Monitoring Long Perimeters. (August 2005) Juan C. Juarez, B.S., Texas A&M University; M.S., Texas A&M University Chair of Advisory Committee: Dr. Henry F. Taylor A distributed sensor using an optical fiber for detecting and locating intruders over long perimeters (>10 km) is described. Phase changes resulting from either the pressure of the in...

Initial Study and Verification of a Distributed Fiber Optic Corrosion Monitoring System for Transportation Structures

Monitoring of Railway Deformations using Distributed Fiber Optic Sensors

Natural phenomena like earthquakes, landslides, avalanches or mud flows can cause severe damages of railway tracks. Today’s monitoring concepts either focus on a permanent monitoring of known problematic sites or an epochwise measurement of the railway track with special measurement cars. In this paper we present a new approach for continuous monitoring of railway tracks over long distances. Th...

Long-Range Pipeline Monitoring by Distributed Fiber Optic Sensing

Distributed fiber optic sensing presents unique features that have no match in conventional sensing techniques. The ability to measure temperatures and strain at thousands of points along a single fiber is particularly interesting for the monitoring of elongated structures such as pipelines, flow lines, oil wells, and coiled tubing. Sensing systems based on Brillouin and Raman scattering are us...
