A ground-penetrating-radar system, and three seismic systems--color fathometer, tuned transducer, and black-and-white fathometer--were used to evaluate river-bed scour at the Charter Oak, Founder 's and Bulkeley Bridges in Hartford, Connecticut. Cross-sections of the channel and some lateral sections were run at each bridge in June and Julyand significant scour at piers supporting each.

Surface-geophysical techniques were used with a position-recording system to study riverbed scour near bridge piers. From May to MayFathometers, fixed- and swept-frequency continuous seismic- reflection profiling (CSP) systems, and a ground-penetrating radar (GPR) system were used with a laser-positioning system to measure the depth and extent of existing and infilled.

Rydlund, Geological Survey (U.S.), and. A new damage identification method for bridge scour was proposed, in the case that it was difficult to detect bridge scour depth applying testing equipment.
Through integrative application of the eigensystem realization algorithm (ERA) and method of support vector machine (SVM), this method was used to identify the scour depths of bridge under conditions of ambient : Xiaozhong Zhang, Wenjuan Yao, Yimin Liu, Bo Chen. This paper offers a broad review of the main aspects to be taken into account when analyzing bridge pier scour: 1) processes: to better understand the dynamics triggering pier scour, an analysis.
Further investigation using invasive methods such as drilling, often into difficult access areas, may then be better focused or not be needed. This paper presents three case studies using surface geophysical methods to assess scour and foundation conditions at existing bridges in Arizona.

NASA Astrophysics Data System (ADS) Capozzoli, Luigi; Giampaolo, Valeria; Rizzo, Enzo. The character (amplitude, phase, frequency, and polarization) of a reflection in a ground penetrating radar (GPR) profile contains a wealth of information about the reflector. However, most of the current research relating reflection strength to material properties, such as soil moisture and the existence of contaminants, involves only single—parallel—component data.
