It has historically been difficult to reliably assess what is happening in the rooting zone of a tree. Whilst core sampling can be useful, it only gives us information at a point in time, rather than informing us of the changes over time, and during different seasons. Modern sensor technology, with state of the art communication equipment has been installed at the Gospel Hall development adjacent to our HQ in East Sussex.
Rainfall data is collected at a weather station, with monitoring points within the soil, and at the outfall point, allowing us to calculate both the attenuation volume and discharge reduction from the ArborFlow tree pit systems.
This data assists with Sustainable Drainage calculations, informing us of the different evapo-transpiration rates for each season, and confirming the efficacy of green infrastructure when used as part of a drainage system.
