Stream-crossing Approaches on Forest Roads Networks: A Critical Review on Practices in Türkiye

Abstract

Appropriate planning and construction of the stream-crossing structures projecting is very important in forest road networks in order to use the roads throughout the planned lifetime and ensure their desired services. Crossing structures in Turkish forestry are planned according to the cross-sectional area value calculated with the Talbot formula which is the general approach to the issue. However, localized precipitation values are not used in the Talbot formula; therefore, significant damages may occur in flood flows due to structural sizing errors. The aim of this study is to suggest a strategy that can be used in Turkish forestry in planning stream-crossing structures.
