Background Fire whirls are often reported to occur in wildland fires and can induce serious difficulties in firefighting by abruptly modifying fire behaviour, exposing firefighters and even causing casualties. Aims The aim of this study was to…

Year Published:

The use of masticated tree debris to protect burned soil from post-fire erosion is not common and very little is known about its effectiveness in reducing the risk of erosion after fire. The main objective of this research was to assess the effects…
