Wild weather causes Grand River to flood

It’s been a wild 24 hours, from temperatures in the twenties, to snow and freezing rain, and in some cases flooding. On a normal day, Wilkes Dam in Brantford flows at about 20 cubic metres per second, right now, it’s moving at about 700. “We’re seeing the river peaking now and through the next day or so.”The Grand River Conservation Authority’s Dave Schultz says the agency has been using its reservoirs to try to keep flooding to a minimum by managing the flow.“There are some road closures and some low lying areas where there is flooding going on right now.”In York, the swelling Grand has temporarily claimed a place to play, and just down the road, a place to rest. Water has come up over the banks in Caledonia as well. Each year the rising water levels brings residents and their cameras to the river. “It’s kind of a bit of a tradition to see how far it goes. So this year it goes to the road,” says one resident.Schultz says it’s best to enjoy the view from a distance. The ground near the water can be very slippery.“The water temperature is maybe a couple of degrees above zero so you won’t last long. And the speed it’s going right now you’ll get carried away before anybody even knows.” read more

Monitoring tailings pipelines CiDRA receives certification for the HALO SMARTring system

first_imgCiDRA has received Class 1 Div 2 certification for its HALOTM SMARTring System. This TUVRheinland Class 1, Div 2 certification now marks the HALO system “TUV approved” for use in hazardous environments containing volatile flammable liquids, gases or vapours. “We put forth a great effort to achieve this certification, in response to our customer’s needs and requirements for services working in hazardous locations,” said Dr. Michael Davis, Principal Scientist, and Vice President of Advanced Technologies with CiDRA. “We will now add this to our current TUV and CE certifications and continue to work with our customers on their applications and certification requirements so that the maximum benefits of our HALO system can be realised.” HALO SMARTtring technology, leverages active sonar and signal processing techniques to provide permanent, fixed multipoint measurements around the circumference of the slurry pipe thereby eliminating manual point-to-point measurements. HALO SMARTring technology and service overcomes the deficiencies of traditional, manual ultrasonic thickness (UT) methods used to measure pipe wear. CiDRA leverages its differentiated sonar and signal processing expertise to provide timely, accurate, repeatable pipe wear measurements and other relevant pipeline information and characteristics. The SMARTring pipe wear measurement tool clamps around the outside of the pipe and remains installed throughout the life of the pipe. On larger diameter pipes, the HALO SMARTring solution features12 measurement locations, equally spaced around the pipe with other configurations available.“On-demand” a CiDRA technician connects a “smart” handheld reader-processor to each SMARTring sensor and acquires the raw signals and performs a first level quality control check for all 12 measurements simultaneously. The measurements are then uploaded to CiDRA’s Data Management Centre where sophisticated signal processing algorithms analyse and perform the final quality assurance check before measurements and reports are generated for the client. Because measurement of all 12 points can be made virtually in seconds, tens of thousands of points on hydrotransport and coarse tailings slurry pipelines can be frequently measured, thereby enhancing predictive modeling and action by client’s pipeline and asset reliability teams.CiDRA’s patented SONARtrac® flow technology has established itself as a new class of industrial flowmeter, using measurement principles that are distinct from all other flowmeter technologies operating today and is ideally suited for measuring flow in difficult slurry applications within the energy and natural resource industries. CiDRA has been aggressively developing various service offerings related to flow management and assurance and overall plant monitoring and process optimisation in mining, including oil sands.last_img read more
