ABSTRACT
The study
examines the hydrogeological conditions and the hydraulic characteristics of
the water bearing horizons within the hydrogeologic regime of the study area
located west of Iraq to the west of longitude 40°40'. Also the study shed light
on the flow behavior regime and its impacts on the groundwater movement, ground
water flow velocities (permeability and hydraulic gradients) considering the
regional structural phenomena. The Hydrogeological data presented as spatial
distribution maps and three dimensional models. The results which were achieved
from the field measurements are correlated with the main hydrogeologic control
points such as storage and transmissivity
coefficients, groundwater depths, aquifers thickness, lateral extensions and
groundwater recharge to classify the hydrogeologic districts for development
and exploitation. The hydrogeologic regime of the study area is classified and
screened into various aquifers, including Ga’ra, Mullusi, Mullusi-Ubaid,
Hartha, Tayarat-Digma (Jeed), Muhaywir-Ubaid and Rattga aquifers. The
statistical results of the hydraulic and hydrochemical parameters were examined
for explaining the spatial distribution of each parameter within the uppermost
aquifers and determining the preference hydrogeologic districts for future
groundwater exploitation as hereinafter order, Ubaid Mullusi aquifer within
district-6, Rattga and Digma-Tayarat aquifer within district-7, Mullusi aquifer
within district-2, Hartha aquifer within district-3, Digma-Tayarat aquifer
within district-4, Ga’ra aquifer within district-1, Muhaywir-Ubaid aquifer
within district-5 and Digma-Tayarat within district-8, respectively.
