حوض وادي بيارة في شمال العراق : دراسة مورفومترية

الملخص EN

The study aims at using GIS technology to detect the morphometric characteristics of the Wadi Biara basin, which is represented by the spatial and morphological characteristics, the dimensions of the basin, the terrain and the characteristics of the drainage network, as well as the identification of drainage patterns in order to build a digital geographic information data base for the basin.

Topographic maps 1: 100000 and digital elevation model (DEM) were used in mapping, topographic mapping and drainage network as well as geological map 1: 250000.

The map of the river network, which was classified according to Striller method to its riverbeds,
The natural factors affecting the basin, especially the rocky nature, climate and topographical characteristics were studied.

The study included the establishment of spatial relations between factors, processes and morphometric characteristics.

The total area of the basin was 93.36 km2, and it was five riverbeds.

These were varied in their numbers and length according to their classes and lengths and the total number of river sewers (649) and total lengths (41.61 km).

Due to the variation in their composition and formation as well as the variation in the environmental factors that make up them, and the differentiated terrain characteristics of the basin of Biara, as it passes the stage of youth and imbalance.
