Identifying thermal plumes quickly and efficiently

By undertaking an aerial survey, our analysts can provide unrivalled data and evidence of thermal plumes. This unique point of visibility can be used for a range of applications in both coastal and inland waters, including leak detection from long sea outfalls, assessing the influence of groundwater upwelling on river flows, and monitoring thermal industrial effluent and oil spills.

There are cost and time benefits to undertaking an aerial survey for thermal plumes. APEM’s approach allows the coverage of large areas quickly and cost-effectively, at a range of resolutions, and allows you to monitor remote or inaccessible locations. This gives our analysts 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 operate the very latest thermographic technology. Combined with our knowledge of water quality, fluvial (river) and coastal processes, we offer bespoke solutions for the detection, evaluation and validation of thermal plumes and pipeline breaches.

By combining thermal infrared and colour optical imagery, we demonstrate how and where thermal effluent discharges into the local environment.

The images reveal the discharges clearly, while the high-resolution full colour images show the interface between the thermal plume and the surrounding environment.

Changes in time and location

By carrying out a series of surveys, we 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. 

By using this multi survey approach, we then work with clients to implement a plan for managing discharges so that they have the least impact on the surrounding environment.
