Temporal Change of Drainage Structures in Forest Roads (Study of Bentler Forest Enterprise 2009-2019)

Abstract

The forest roads provide access to forest resources in carrying out main forestry activities such as protection, afforestation, management, recreation and firefighting. Long-term, trouble-free and safe use of forest roads is possible through the construction of the drainage structures and walls along the road alignment. The drainage structures and protective structures used in forest roads are various types. These are dip drains, pipes, culverts, bridges, water-bars and walls. The main task of all drainage structures and walls is protecting the forest roads against external aggressors. In this study, drainage structures on a sample road were investigated. Along the forest road alignment, changes of drainage structures over 10 years were observed. As a result of the study, current conditions of drainage structures were revealed and various suggestions were presented.
