حوض وادي نخلة : دراسة جيومورفولوجية كمية

Abstract EN

This paper presents the quantitative geomorphological study with in the first part the analysis of characteristics of geological and climatic characteristics and identify geomorphological forms with its map in the Nakhala drainage basin.

Also, the second part studies : - The current erosion estimation using a mathematical model based on calculation of area excavated and the calculation of volume engraved on 35 topographic cross-section was chosen on the main tributaries of the Wadi Nakhala.

- The aeolian erosion using a Bagnold's Formula and the discharge of flood using Creager's Formula.

The tributaries basins has been classified by excavated area, excavated volume, specific erosion and discharge peak completed with the classification map.

- The Wadi Nakhala hydrographs of discharge peak of return period 50 , 100 and 200 years are been designed.
