استخدام نظم المعلومات الجغرافية في تصميم العبارات والجسور للطرق الخارجية

Abstract

In this research geographic information systems (GIS) were used to analyze the basic features of the catchments on the study area and to processing and establishment the data for the bridges and culverts design process of (Kubaisa-Highway) road in Al-Anbar province in western Iraq from the point (0 km) near the Kubaisa city, to the point (41.5 km) where the road crossing the international highway. Hydrological and climatic data were collected for the study area, and soil texture analysis for selected soil samples from study area were performed. Hydraulic calculations have done to estimate the maximum flood discharge of valleys cutting of the road for various flood return periods, and identify points of intersection between the valley and the road, and suggest the size of bridges and culverts to be used in the study area.
