The dranaige systems in village roads transportation networks and hydraulic design principles

Todays, in our developing country , for reflection of development homogeneously in all country , transportation to our smallest settlements those are villages , must be provided in everytime and in every air conditions. This can be provided , by designing and applying, the dranaige systems those are required in our village roads. In this study, the underground and surface dranaige of roads those are in village roads network, is examined and hydraulic design criterions of these systems is handled in detail. In the beginning of the study , the definition of village roads is made and the forms of availability of water in floor and under ground waters are examined. In the second chapter, the subject of dranaige,under the subtitles of the dranaige of underground water and surface dranaige are examined in detail. In third chapter, subject of small art structures is examined. In this chapter , the kinds of vents and its' hydraulic design principles ara examined in detail. Also brit, drift and river crossing are examined. In the last chapter, the results those reached from this study are explained.
