RISMesoscale Current Fields Observed with a Shipboard Profiling Acoustic Current Meter
Publisher: American Meteorological Society
Abstract: Measurements of the near-surface currents obtained with a shipboard profiling acoustic current meter during the POLYMODE Local Dynamics Experiment are discussed. The large-scale spatial structure of the directly measured ...
Distributed Strain Behavior of a Reinforced Concrete Bridge: Case Study
Publisher: American Society of Civil Engineers
Abstract: To effectively assess and manage aging infrastructure, sensing technologies that produce accurate and useful quantitative data are required. Distributed fiber optic strain measurement systems are one potential technology ...
Vorticity and Vertical Circulation at an Ocean Front
Publisher: American Meteorological Society
Abstract: Density and velocity data with 4-km horizontal resolution from a survey of a front during FASINEX (Frontal Air-Sea Interaction Experiment) are combined to describe the structure of the top 300 m of the ocean. The geostrophic ...
Use of Underwater Gliders for Acoustic Data Retrieval from Subsurface Oceanographic Instrumentation and Bidirectional Communication in the Deep Ocean
Publisher: American Meteorological Society
Abstract: any fixed oceanographic instruments and observing systems are deployed in the water column or on the seafloor for extended periods of time without any expression at the sea surface. To routinely communicate with such ...
Damage/Deterioration Detection for Steel Structures Using Distributed Fiber Optic Strain Sensors
Publisher: American Society of Civil Engineers
Abstract: Distributed fiber optic sensors have the potential to be used to detect three critical deterioration mechanisms in steel structures: (1) fatigue cracking, (2) localized damage or deterioration, and (3) distributed damage ...
Laboratory Study on the Behavior of a Horizontal-Ellipse Culvert during Service and Ultimate Load Testing
Publisher: American Society of Civil Engineers
Abstract: Horizontal-ellipse culverts have been used for many years as a substitute for more conventional short-span bridges; however, their performance has never been evaluated experimentally. This paper describes an experimental ...
Comparison of Shipboard Acoustic Doppler Current Profiler and Moored Current Measurements in the Equatorial Pacific
Publisher: American Meteorological Society
Abstract: Depth-averaged current shears computed from shipboard acoustic Doppler current profiler (ADCP) and moored Savonius rotor and vane vector-averaging current meter (VACM) measurements are compared at 35, 62.5, 100 and 140 m ...
A Study of Geostrophy in Tropical Pacific Ocean Currents during the NORPAX Tahiti Shuttle using a Shipboard Doppler Acoustic Current Profiler
Publisher: American Meteorological Society
Abstract: Continuous velocity measurements from a shipboard Doppler acoustic long on the NORPAX shuttle experiment in the central equatorial Pacific are presented. The time mean of these velocities shows the classical zonal equatorial ...
Remaining Strength of Deteriorated Corrugated Steel Culverts
Publisher: American Society of Civil Engineers
Abstract: Currently, corroded corrugated steel culverts are typically assessed based on the results of visual inspections that provide qualitative data about corrosion levels. However, there is a lack of experimental data relating ...
Hydrologic and Water Quality Performance of Two Bioswales at an Urban Farm
Publisher: ASCE
Abstract: Many postindustrial cities are transforming underused areas into urban agriculture, which presents unique stormwater management challenges. One way to manage runoff from urban agriculture is to use green stormwater ...
