Surface flows from images: ten days of observations from the Tiber River gauge-cam station
Fully remote surface flow measurements are crucial for flow monitoring during floods and in difficult-to-access areas. Recently, optics-based surface flow monitoring has been enabled through a permanent gauge-cam station on the Tiber River, Rome, Italy. Therein, a system of lasers and an internet protocol camera equipped with two optical modules afford video acquisitions of the river surface ...

Inside the Particulate Monitor – Optical Methods
At least two different optical techniques can be applied to measure the concentration of particulates – light absorption and light scattering. Light absorption is frequently used in high-concentration industrial processes, but it has some applications also in ambient air, for example to determine visibility at airports. Light scattering is utilized both in industrial and ambient ...

Affinity–based biosensors for heavy metal detection
In recent years, there has been a pressing need for fast and reliable methods for environmental monitoring. Among the various pollutants, the heavy metals are some of the most harmful because these substances are non–biodegradable and retained by the ecological system. Conventional analytical techniques for heavy metals imply high cost, trained personnel and the repute that they are mostly ...

Pipeline Integrity Monitoring Overview
Understanding Pipeline Integrity Pipeline integrity is all about keeping pipelines operating properly throughout their life cycle. From design and construction to maintenance and inspection to decommissioning and retirement, pipeline integrity engineers work to ensure pipelines and their related components are reliable, sustainable, and safe throughout their service life. Pipeline integrity can ...

PME’s miniDOT® logger Aids Researchers in Dissolved Oxygen and Temperature Monitoring
The origin of the miniDOT® Logger came from a quick sketch on a napkin in a bar by the founder of PME, Mike Head in 2009. From there the R&D process began and the miniDOT’s first calibration was made in 2011. For more than a decade, miniDOTs have been chosen by researchers, universities, and government agencies worldwide to learn more about the water around them and provide the ...

Ping-ping, what’s that sound? Acoustic fiber optic technology helps identify problematic water mains
With the deteriorating state of many aging water mains found in cities across North America, urbanites are frequently witnessing unexpected plumes of water erupt as man-made geysers in their own metropolitan backyards. While natural geysers are awe inspiring, urban geysers are much less so, due to their destruction to property, roads and the environment. Because an uninterrupted water flow is ...

Spectroelectrochemistry: shedding light on the unknown
The combination of two well-known analytical techniques, electrochemistry and spectroscopy, gives rise to spectroelectrochemistry (SEC), an established scientific methodology. This hybrid technology combines the advantages of each technique, offering the best of both worlds [1]. The word «spectroelectrochemistry» is the result of combining these two terms as two pieces of a puzzle ...

Using distributed temperature sensors to monitor an Antarctic ice shelf and sub-ice-shelf cavity
ABSTRACT. Monitoring of ice-shelf and sub-ice-shelf ocean temperatures represents an important component in understanding ice-sheet stability. Continuous monitoring is challenging due to difficult surface access, difficulties in penetrating the ice shelf, and the need for long-term operation of non-recoverable sensors. We aim to develop rapid lightweight drilling and near-continuous fiber-optic ...

Case study - Washington Suburban Sanitary Commission
After WSSC began experiencing major PCCP failures in the 1970s, it developed a strong commitment to infrastructure management technology in favor of large capital replacements. Beginning in 2007, WSSC and Pure Technologies began a partnership to create a comprehensive PCCP management program. The Washington Suburban Sanitary Commission (WSSC) is the 8th largest water and wastewater utility in ...

Rockfall precursor detection based on rock fracturing monitoring by means of optical fibre sensors
The monitoring of the acoustic emissions (AEs) due to rock fracturing allows the detection of the rockfall precursor signals, leading to a strong improvement of the real time assessment of the induced risk. A network of piezoelectric sensors (PZTs) provides reliable AE data, as testified by a series of applications in non–destructive testing, but PZTs are strongly affected by lightings and ...
