Abstract
In the current work, the spatial
distribution of the precipitation in Iraq were reviewed, as it is considered as
one of the most important parameters that controls groundwater recharging. In
addition, the physiographical divisions of Iraq had been assessed as it is
contributing in determining the groundwater aquifers, as well as a review of
the division of the main groundwater aquifers. Subsequently, a review of the level and
depths of groundwater, the regional trends of its flow, the variation of its
specific quality (especially salinity), and its suitability for multipurpose,
throughout of the Iraqi territory had been conducted. The characteristics of each region were
highlighted separately, including the detailed aspects that relate to the
groundwater recharge, quality flow of groundwater, the hydraulic
characteristics of the groundwater aquifers, the problems facing the
groundwater sector, and the development of recommendation in terms of the
optimal investment and development of groundwater resources in each region.
