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

European Journal of Forest Engineering, cilt.6, sa.2, ss.52-59, 2020 (Scopus, TRDizin)

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.
