Ecological engineering is the design of sustainable ecosystems that have value to humans as well as the environment and that can help to solve global problems. For instance, examining time-changing water temperatures can be useful to understand how rivers and streams work and to prevent irrigation.
Seepage Monitoring in dams and dykes
One of the major causes of failure in dams and dykes is internal erosion that results in increased seepage flow. This becomes a concern if the flow carries material with it, and should be controlled to prevent erosion of the embankment, foundation, or damage to concrete structures. Continuous monitoring of these structures can be of vital importance as they, on a larger scale, may lead to the failure of the dam or dyke.
However, many existing seepage monitoring systems are not sensitive enough to detect small changes in the seepage flow. With a possibility to detect changes/effects down to 20µe caused by time-dependent processes, such as internal erosion, LIOS PRE.VENT overcomes this issue and is a very precise and effective method for seepage monitoring.
Underground storage facilities
Caverns and aquifers are widely used for underground storage of gas and mineral oil products. In most cases, the underground installations are not accessible and the operating pressure and temperature are critical parameters that require constant monitoring to assure the integrity of the structure.
Underground storage facilities are costly to construct and operate, and the materials they contain are potentially harmful if allowed to escape into the atmosphere. Consequently, there is an essential need for monitoring and surveying both the operation of the underground storage facility and the conditions of the underground installations to protect the investment and to assure the safety and reliability of the operation.
LIOS PREVENT: A robust and precise solution for ecological engineering
Through continuous temperature monitoring, LIOS PRE.VENT shows temperature changes as a function of the time of day, tides, rainfall, seasons, and other variables providing invaluable insights into environmental processes. With its DTS technology LIOS PRE.VENT is the perfect, robust solution to detect, precisely monitor, and locate any temperature changes caused by for instance erosion or gas leakage.
Our innovative and patented OFDR evaluation method can determine a continuous temperature profile along the entire length of an optical fiber, offering thousands of data points at a single measurement. The software visualization with data analysis allows the making of qualified decisions regarding utilization and life extension, which can lead to considerable cost savings.
Unexpected shut-downs or potentially harmful situations can be prevented or postponed which increases the operational reliability and safety and makes maintenance easier.
