Abstract

:The area located between Al-Khosar river catchment and Bashiqa anticline differs
morphologically and lithologically .The study showed that there are differences in the slopes of these rocks
caused by structural and denudational factors .Geomorphological analyses to the prevailing flow net have been
carried out and the results show that the region is stable with bifurcation ratio ranging between (3.1-4 )and
drainage density of (1.45 Km-1 ). Moreover a comprehensive field survey was performed taking into consideration
the important groundwater wells in the area in order to give an evaluation of water quality Most of these wells
penetrate Injana Fm .With depth less than 30m .But few of them penetrate deeper Al-Fatha Fm .Of more than(
150m).Fifteen groundwater samples were collected from the whole area on three stages , i.e .March , June , and
September 2010 and appropriate Laboratory analyses were done .The results shown in the tables represents the
mean of the three readings .The study also revealed that groundwater in the area is not suitable for drinking due to
a high concentration of dissolved solids (T.D.S ).which frequently exceed the world standard limits while a high
concentrations of (Na +, SO4=), and electrical conductivity have been observed in the south and southwest
direction very close to Al-Khosar river catchment .In general the groundwater of most wells in the area could be
considered suitable for Irrigation purpose .
