The statistical Study of Jointsarround 16 Tishreen lake dame region in ALKabir
ALShimali river basin showed the presence of several main groups of Joints with
directions NE-SW _ NNE-SSW, NW-SE, E-W.
- Group NE-SW: showed correspond to with the fau
lt structures of same directions
which are normal and reversal faults and distributing geographically 1n Lattakia Kallas
fault zone. Also it showes correspond to with the axis of folds of same direction, thus
explained as longitudinal joints within these folds
- Group NW-SE: showed correspond to with faults structures of same direction.
which are left and right lateral strike slip faults, Spread over the entire study area. and it
may(diagonal)shear group within the folds of NE-SW axes.
- Group E-W:correspond to with normal faults structures.
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 stu
dy 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.
