Abstract EN

This study aims at analyzing the geomorphological characteristics of the waterfalls in Wadi Al-Wala, North of Jordan.

This study attempts to clarify the physical factors that affect the phenomenon of waterfalls along the longitudinal profile of the valley.

In addition, it attempts to analyze the morphometric characteristics of the waterfalls in Wadi Al-wala and their geomorphological indications.

To achieve the objectives of this study, the researcher reviewed the related literature and conducted field measurements of water and morphometric characteristics of waterfalls along the longitudinal profile of the valley.

The findings of the study were tested using advanced statistical analysis with stepwise regression to indicate their role in determining the stream energy of the waterfalls.

The findings of the study showed that the waterfalls geomorphological development and the different morphometric characteristics of waterfalls in Wadi Al-wala reflect the direct response to the changes that affect the environmental characteristics of the basin : the degree of slope, the amount of water discharge, the morphology of river bed, and the types of rocks.

The findings of the statistical analysis indicated the importance of water discharge and the slope degree in explaining the variance in the stream energy of the waterfalls, and the two variables are statistically significant.

The water discharge variable was (21 %), and it was statistically significant at the level (0.001) and the variable of slope was (13 %) which was statistically significant at the level (0,001).
