Abstract
This study deals with the spatial distribution of hydrogeological and hydraulic characteristics of the groundwater in Khanaqin sub-basin. The study area is located between (45.00- 45.69) east (34.00 - 34.95) north. The raw data are taken from the hydrogeological technical report of the General Groundwater Authority. The study shows that the depths to groundwater vary as a result of the topographic variation and the lithological characteristics of the aquifer. Consequently, the depths range from (4 to 40) m. The groundwater levels vary between (45 and 564) m. The study shows that the groundwater flow trends are generally northeast to southwest on both banks of the Diyala River, which recharged from groundwater based on data from equipotential lines. The difference in depths and levels is reflected in the other hydraulic properties, as the values of transmissivity (T) range (from 40 to 549) m²/day, and hydraulic conductivity (K) that also affected by the variation of the lithology and groundwater aquifer thickness from one place to another; they are elevated in northeast to southwest in the form of a strip parallel to Diyala River and range (from 1 to 25) m/day, and the pumping rate is also different, as its values range (between 59.27 to 4492) m³/day. Therefore, the variation in the drawdown may be due to natural characteristics resulting from the lithology of the groundwater aquifers or due to the neglecting of the basic criteria in determining the suitable pumping equipment, as the values of the drawdown are (between 0.11 and 61) m.
