Numbers don’t Lie, PCCP performance and deterioration based on a statistical review of a decade of condition assessment data
Abstract Since the late 1990s there have been numerous inspection and monitoring projects focused on identifying and quantifying wire break damage in PCCP water and wastewater pressure mains. The pressing need to identify and manage deterioration of PCCP has resulted in the rapid development of a small but highly focused niche industry of condition assessment of PCCP mains. During this time, ...

How listening to the ocean can help reveal environmental damage
In 2013, Katherine Indeck listened to recordings of sounds made in a channel between the Gulf of Mexico and Tampa Bay, Florida. Some of the audio files had been collected in 2005 during an unusually severe red tide, a bloom of toxic algae that killed fish, dolphins and sea turtles. Other recordings were made after the ecosystem began to recover. During the recovery years, Indeck could hear ...

Coupling acoustic devices for monitoring combined sewer network sediment deposits
Combined sewer networks display some unique features that are not easily reproducible in the laboratory and have yet to be well understood. The transport of organic and mobile sediments, present in large quantities despite the use of optimal design practices, dramatically changes sewer flow patterns and the interaction between flow and sediment. To understand both the flow patterns and ...

Distributed Thermal-Acoustic Data Integration
Silixa has developed a technique called Distributed Thermal Acoustics (DTA) to monitor simultaneously the thermal and acoustic profile along a hybrid optical fibre cable in submarine environments. Using its world leading distributed fibre optic technology (ULTIMATM DTS and iDASTM) Silixa deployed an optical fibre cable along the seabed and across the water column in an active gas seepage field. ...

Device combines pressure monitoring with acoustic leak detection
In the world of municipal water and sewer maintenance, leaks are money. Not only does that mean money down the drain, but technically right out the drain as well. Those additional treatment and conveyance costs mean not only decreased revenue, but also increased costs in leak detection and pipeline repair. To combat the issue, Syrinix has launched the PIPEMINDER-ONE Acoustic, a device that ...

A novel acoustic imaging tool for monitoring the state of rapid sand filters
A new technology based on acoustic waves is developed to monitor the state of sand filters used in drinking water treatment. Changes in the sand filter, due to the removal of suspended particles from the water and their accumulation in the pores, result in an increase of the bulk density and acoustic speed of the granular material. Consequently, the reflected acoustic response changes as the ...

Top trends conservationists should be paying attention to — but aren’t
Artificial intelligence, testosterone and ship tracking technology probably aren’t on many conservation organizations’ “top things to think about” lists right now. But they should be, suggests a new report in the scientific journal Trends in Ecology & Evolution. “A Horizon Scan of Global Conservation Issues for 2016,” authored by University of Cambridge ...

Ocean science for sustainable development: Facts and figures
Sarah Grimes explores why we need good ocean monitoring, how to get it, and why it still fails Small Island Developing States. Oceans are a critically important component of the Earth system, supporting ecosystem and human health. They regulate the weather and climate; are essential for producing freshwater; and soak up carbon. They also provide food and other resources, trade and migration ...
