Analysis of water flow through objects on forest roads

Abstract

The forest roads usually lay along streams and torrents and often cross them. In these places the bridges are built and the pipe culverts are depending on conditions of basin. The dimension of clean opening of bridges or diameter and number of culverts depend on amount of a high water which can expect from basin over a flow section. The high water which can expect from basin depend on: basin shape and area, length and slope of stream or torrent, soil and the other conditions. In management unit “Prosara” on forest roads there are two pipe culverts over Pisarić and Hajduk’s stream and two bridges over stream of Eškerovac and Gašnica. Their permeability will be analyzed in this paper.
