 This study focused on the upper basin of wadi Al-Khaleel. It has been studying the physical factors in the study area to determined their influence in the geomorphological formation of the area. The study contains:
1- Studying the climatic factors (rain and temperature)، which considered  an important elements in the Geomorphological formation of the area by  weathering and denudation.
2- Studying the biological factors (Plants Animals Human) ; and analyzing their influences on geomorphological Landscape of the study area. 3- Analyzing the roles of geological factors such as folds، faults and rock formations in forming the natural surface of study area.
4- Classifying geomorphological features existing in wadi Al-Khaleel  according to their forming factors and developmental stages as the following:
A) Geomorphological features of fault origin.
B) Geomorphological features of horizontal structure formation.
C) Geomorphological features resulted from denudation process which  includes depositions and caristification features.
5- Studying the hydrological network and its geomorphological and  Morphometrical characteristics، where became clear that: the  Geomorphological characteristics of the drainage system were affected by  the natural characteristics of wadi Al-Khaleel. The joints determined the  drainage system directions. And the research used several Indexes and  equations that usually used in such quantitative studies.
6- In the applied Geomorphology، the study shed light on: Analyzing the  influence of slops on the land use in the study area.  The study reaches many conclusions such as:
A) It might be concluded that the origin of wadi Al-Khaleel dated back to Oligocene Pleistocene.
B) The study ranked stream meandering by an Index that suggested by the  researcher. Which based on the relationship between wave amplitude and wave  length of the meander.  Finally the study recommended to make several environmental and  hydrological studies in the area.
