نظام المياه الجوفية الحرة في المنطقة الواقعة بين نهري الصنوبر والكبير الشمالي

This is a study of free groundwater level changes through time, and the level of its being affected by natural and artificial factors, which allows evaluating general water situation of the aquifer. This study shows that groundwater system in the study area from the type of water division line (climatic system) connects in direct connection with infiltration from rainfalls in which the natural factors (recharge) play the main role in forming the system of groundwater, in addition to the artificial factors (irrigation), and these factors yield three periods of the obvious terminal changes of the levels in hydrologic year (descending, stability, ascending). However, groundwater is renewable because of stability in the situations of this water, and its discharge to hydrodynamic net of groundwater in Al-kabir al-shimali and Al-snobar rivers and in the Mediterranean Sea as well.
