Simulation of the ground water flow in Karbala Governorate, Iraq

Abstract

The investigation region is found in the central part of Iraq within the of Karbala Governorate, where it is located in the western part of the Governorate and Lake Razaza in the north of the region, while in the western and southern part of the region is Anbar Governorate and geographically (43° 10′ 25.7″, 43° 39″ 0.3″) longitude and (32° 10′ 25.7″, 32° 36′ 25.7″) latitude. The area of study is about 2400 Km2. The groundwater modeling system (GMS) v10.3 program was used for the modeling of ground water in the area containing about 22 wells distributed throughout the study area and the discharge of these wells ranges from 7 to 100 l/s and the rate of discharge of these wells up to 36 l/s. The model was initially operated within a steady state and after obtaining a match between the models results with the initial values of groundwater levels, the results of this case were adopted as inputs to run the model within the unsteady state. The model was worked within the sight of the above wells for 3 years and the results of the operation indicate a decrease in groundwater levels ranging from 2 to 21 m distributed uniformly throughout the study area.

Developing three-dimensional groundwater flow modeling for the Erbil Basin using Groundwater Modeling System (GMS)

“…The literature review presents a comprehensive overview of groundwater studies conducted in various regions of Iraq, focusing on factors such as movement, recharge, and management. In a study by Hussain (2008), groundwater flow within the Sullivan plain was estimated to be approximately 579,655 m 3 /d. Subsequently, Hussain applied two numerical models to assess groundwater recharge in Karbala, utilizing GMS software with the MODFLOW package and Quick Basic language for mathematical modeling.…”
