Abstract

Due to the recent impacts of climate change, forest fires are becoming more frequent and larger throughout the year. There is controversy over whether forest roads increase the risk of fire hazard by providing wind corridors. However, there is no scientific evidence to support these claims. More than research on the interaction between forest roads and wind is required. This study installed wind speed and wind direction sensors in two large forest fire areas (Site 1: Goseong-gun, Gangwon-do (GG), Site 2: Uljin-gun, Gyeongsangbuk-do (UG) at various forest road locations (valley, ridge, and slope) and forest. Data was collected during the spring and summer to analyze wind characteristics related to the forest road facilities. The wind direction analysis in two large forest fire areas revealed diverse patterns unrelated to the location of forest roads. Also, forest roads needed to channel or affect wind flow consistently. The wind speed analysis showed significant wind speed differences related to forest road locations within forest areas in GG, regardless of the period (p < 0.05). Wind speed intensity followed the ridge, valley, slope, and forest order. Similarly, in UG, significant differences in wind speed were observed (p < 0.05). During the spring, wind speed intensity ranked as forest, valley, ridge, and slope; in the summer, it changed to forest, slope, ridge, and valley, depending on different location conditions (regional characteristics) and terrain. Considering that only the spring and summer seasons have been examined, additional data analysis for all four seasons is necessary.
