IET Networks, EarlyView., 2022 Abstract This research aims to study the intelligent wireless sensor to improve the water permeability of permeable asphalt concrete pavement. The water permeability of pavement is extremely important for the traffic environment. This study first briefly introduces the background and significance analysis, and then exemplifies the deployment algorithm ...

Calculating the correction factor of skidding distance based on forest road network
Journal of Forest Science, 2011 Average skidding distance for forest stands is an important parameter for the determination of the optimum road density and spacing. In this research the real mean skidding distance and theoretical mean skidding distance were measured to calculate the ...

Productivity of a Portable Winch System Used in Salvage Logging of Storm-Damaged Timber
Croatian Journal of Forest Engineering, 2019 Storm damages result in serious losses in many regions, primarily by stem breakage or blowdown. Extraction of storm-damaged trees often requires more difficult than normal skidding activities due to obstacles created during the storm.

Changes in soil physical properties and understory vegetation in abandoned skidding trails
Folia OecologicaSkidding trails are primary pathways for transporting harvested timber from stumps to landings near forest roads. While they function as temporary routes for logging, their construction can alter ecological dynamics, potentially affecting plant ...
