Benefits of aerial surveys for thermal plumes

APEM’s aerial thermal surveys allow us to cover large areas quickly and economically at a range of resolutions, and to monitor remote or inaccessible locations. This gives our scientists a powerful tool with which to survey and monitor the effect of thermal plumes and effluent on protected or sensitive ecosystems.

How aerial surveys of thermal plumes work

APEM operates the very latest thermographic technology in our fleet of survey aircraft. Combined with our knowledge of water quality, fluvial and coastal processes, this allows us to offer bespoke solutions for the detection, evaluation and validation of thermal plumes and pipeline breaches.

We combine thermal infrared and colour optical imagery to show how and where thermal effluent discharges into the local environment.

The images reveal the discharges clearly, while the high resolution colour images also allow the interface between the thermal plume and the surrounding environment to be easily identified.

Changes in time and location

By carrying out a series of surveys we are able to monitor how large-scale thermal or pollutant plumes change and develop in terms of temperature, tides and discharge regimes.

Thermal plume surveys can also determine whether a plume exits at the end of an outfall pipe or if breaches occur along the length of the pipe. In addition, the extent of the plume and any associated mixing zone can be assessed.

We then work with clients to implement a plan for managing discharges so that they have the least impact on the surrounding environment.
