Groundwater in arid and semi-arid regions, such as the studied area (Safwan Al-Zubair area, south of Iraq), is of specific meaning as a major source for domestic use and irrigation demand. There is a need to better understand the interactions between groundwater and surface water (Shatt Al-Basrah Canal). These interactions can negatively affect the quality of groundwater in this area, especially that the water of Shatt Al-Basrah Canal contains highly concentrated pollutants. The aim of the study is to investigate the temporal disparity of river-aquifer interactions and count the amount of river interchange among canal and aquifer. In this research, a new concept of paradigm will be advanced utilizing RIVER package of Groundwater River Paradigm (MODFLOW) for the simulation of river-aquifer interaction operations. Six monitoring wells are chosen to evaluate the preliminary and historical groundwater hydraulic heads for six months and then use all collected data in Modflow to execute the simulation of numerical modeling to assessment the interaction between surface water and groundwater. The amount of seepage out from the canal towards the aquifer was (64.99 m3/day) in wet season (winter season), as a result of the high levels of the surface water compared to the hydraulic heads of groundwater. The amount of seepage in dry season towards the aquifer is equal to (336.8 m3/day).

“…Depending on the observation period (one year) in the study area, the change in the groundwater level is 0.5 m (see Eqs. 10 ,11 ), and it is more realistic to take a value corresponding or greater than this hydraulic head (Al-Aboodi, et al, 2013).…”

A two dimensional mathematical model is developed to simulate a groundwater flow regime of the upper part of Quaternary Deposites, in the Teeb area, Missan province. The optimum management of groundwater flow is developed by a linking simulation-optimization model. In this study, MODFLOW, 98 packages are used to simulate the groundwater flow system in unconfined aquifer. This model is integrated with an optimization model (Modular Groundwater optimizer) which is based on the simulated annealying (SA). Fixed well location case was undertaken by running the model with adopted calibrated parameters. The optimum value of pumping rate estimated through this study is (108320 m3/day), this value is compared with another previous work which based on genetic algorithm GA for the same area. The results of comparison showed that the optimum value obtained by SA is higher than the one obtained from GA by 18.35% for the same piezometric head draw down that indicate, the SA gives higher value than GA in this study.

“…Well-pumping and pond water filtration are the two most common methods of artificial recharge. Because evaporation is higher in these surface water ponds than in wells and because considerable volumes of raw water are lost, wells were employed to recharge the aquifer in this study [26][27][28].…”

In arid and semi-arid countries like Iraq, which suffer from water scarcity due to the effects of climate change and decreased surface water flow, groundwater is considered a vital source of irrigation water. This study is concerned with the influence of artificial recharge on the rehabilitation of the unconfined aquifer called Al-Dibdibba, located between the cities of Najaf and Kerbala in central Iraq around 31°550′ N and 32°450′ N and 43°300′ E and 44°300′ E. Due to excessive groundwater pumping rates for irrigation, this aquifer has suffered from groundwater decline and increased salinization during the previous 20 years. By establishing a conceptual model in the groundwater modeling system software (GMS), a numerical model was made to simulate groundwater flow. Artificial recharge using recycled water (tertiary treatment) from Kerbala's primary WWTP was carried out using 25 injection wells. The model was calibrated against historical and observed water level data for periods from 2016 to 2017. Three scenarios to predict how the aquifer would act with artificial recharge of 5%, 8%, and 10% from the total daily outflow of the WWTP in Kerbala (100000 m3/day) were studied. The calibration model met the observed values of groundwater levels with R2 = 0.989 for steady-state simulations and R2 = 0.987 for transient simulations. In the final analysis of the simulation, the results show that the maximum predicted groundwater level was raised by the injection of treated water through 25 wells by 1.05 m for 5000 m3/day, 2 m for 8000 m3/day, and 3 m for 10,000 m3/day recharge pumping rates. In addition, if water were pumped into the aquifer, it might support the development of agricultural lands covering more than 93 km2. So, artificial recharge can be considered one of the important solutions to adaptation to the effects of climate change and desertification in Iraq. Doi: 10.28991/CEJ-2023-09-09-010 Full Text: PDF
