Hydraulic Characteristics of Dammam Aquifer in Sayed Al-Shuhadaa Agricultural city, Karbala- Iraq

Abstract

This study's objective is to investigate the hydraulic properties of the Dammam aquifer utilizing three acceptable pumping wells for experimental pumping. The location under study is an agricultural project known as Sayed Al-Shuhadaa agricultural city, which is located in the Al-Ukhaidir section of the Ain Al-Tamar district, to the southwest of Razzaza Lake and west of the Holy Karbala province. Theis and Hantush methods had been applicated to analyze pumping test data. The ranges for transmissivity, hydraulic conductivity and storage coefficient are (111.3 - 1705.1) m2/day, (22.23 - 32.11) m/day, and (0.00075-0.0011) respectively.  The agricultural city of Sayed Al-Shuhadaa was formerly a desolate desert, but it was transformed into an agriculturally productive region after (5000) donams of wheat were cultivated this season. The most important characteristic of this region is the use of pivotal irrigation systems of global origin, and the water source used in the farm is from the ground sea (groundwaterwater), as this source provides greater assurance of the sustainability of the farm's production, and aims to determine the hydraulic characteristics of the aquifer in the event that suitable wells are available for pumping tests. Calculating water excess and shortfall by performing the water balance. Assessing the appropriateness of groundwater for agricultural and irrigation purposes by analyzing its hydrochemical properties and quality. An attempt to implement a plan for agricultural groundwater management.
