    Assessment of Groundwater Vulnerability in Northern Babylon Governorate, Iraq2016In: Engineering, ISSN 1947-3931, E-ISSN 1947-394X, Vol. 8, no 12, p. 883-902Article in journal (Refereed)
    Abstract [en]

    Groundwater is one of the main resources from the earth, especially for arid or semiarid

    countries. For this reason, it is very important to keep it unpolluted. Drastic

    Model is one of the widely used models to detect groundwater vulnerability to the

    contaminants that are found on ground surface. In this model, it is assumed that the

    vulnerability of the groundwater is affected by seven hydrological parameters. They

    are: depth from the surface ground to groundwater, net recharge into the aquifer

    from the surface, aquifer media, soil media, area topography, impact of vadose zone

    and aquifer hydraulic conductivity. In this study, the DRASTIC model was applied

    on the northern part of Babylon governorate in Iraq, to predict the vulnerability of

    Groundwater in that area. The results indicate that the vulnerability is very low to

    low grade.

    Seepage Velocity of Dibdibba Formation in Karbala, Iraq2017In: Engineering, ISSN 1947-3931, E-ISSN 1947-394X, Vol. 9, no 3, p. 279-290Article in journal (Refereed)
    Abstract [en]

    Iraq highly depends on its surface water resources. Now it is facing water shortage problems. For these reasons, the utilization of groundwater will be increasing with time. Karbala Governorate is located in the central part of Iraq. It covers an area of 5034 km2 and the population exceeds one million. It is characterized by an arid or semiarid environment. Karbala Governorate lack surface water resource and consequently, groundwater is the only available resource. The main groundwater aquifer within the area is Dibdibba formation. It is composed of poorly sorted sand and sand stone with gravel. In this research hydrological and hydrogeological information were used to find out the magnitude and the direction of groundwater seepage velocity. The results indicate that groundwater flow toward the flood plain to the east of the study region. The seepage velocity ranges from 0 to 0.18 m/d, with a general increase when moving from the west to the east.

    Site Selection of Aquifer Thermal Energy Storage Systems in Shallow Groundwater Conditions2019In: Water, ISSN 2073-4441, E-ISSN 2073-4441, Vol. 11, no 7, article id 1393Article in journal (Refereed)
    Abstract [en]

    Underground thermal energy storage (UTES) systems are widely used around the world, due to their relations to heating ventilating and air conditioning (HVAC) applications [1]. To achieve the required objectives of these systems, the best design of these systems should be accessed first. The process of determining the best design for any UTES system has two stages, the type selection stage and the site selection stage. In the type selection stage, the best sort of UTES system is determined. There are six kinds of UTES systems, they are: boreholes, aquifer, bit, tank, tubes in clay, and cavern [2–5]. The selection of a particular type depends on three groups of parameters. They are: Site specific, design, and operation parameters (Figure 1). Apart from site specific parameters, the other two types can be changed through the life time of the system. The site specific parameters, e.g., geological, hydrogeological, and metrological, cannot be changed during the service period of the  ystem. Therefore, the design of the best type should depend, at first consideration, on site specific parameters.

    Site Selection Criteria of UTES Systems in Hot Climate2019In: Proceedings of the XVII ECSMGE-2019: Geotechnical Engineering foundation of the future, Iceland: The Icelandic Geotechnical Society (IGS) , 2019, Vol. 1, p. 1-8Conference paper (Refereed)
    Abstract [en]

    Underground Thermal Energy Storage UTES systems are widely used around the world. The reason is that UTES is essential in utilizing Renewable Energy sources (RE). The efficiency of the energy system relies strongly on the efficiency of the storage system. Therefore, in the installation of a hyper-energy system, a lot of attention is to be paid in improving the storage system. In order to design an efficient storage system, firstly, standard criteria are to be investigated. These explain the process of making high efficiency storage system that must be specified. The criteria, mainly, depends on: best type and best location. These two variables are in high interference with each other. The bond between the two variables is represented by the geological, hydrological, meteorological, soil, hydrogeological properties/factors of the site. These factors are specified by geo-energy mapping. Despite the importance of this type of mapping, there is no specific criteria/formula that defines the choice. This paper aims to: give a brief literature review for UTES systems (types, classification, advantages/disadvantages for each type, and examples of an installed system). In addition, some factors within geo-energy mapping are highlighted and standard criteria to achieve good storage system are suggested. The suggested criterion comprises a process to transfer the quantity values to quality values according to the expert opinion. The suggested criteria are defined through the following stages: selecting the best type of UTES systems according to hydro-geological in site conditions; using the analytical hierarchy process to rank the best location to install the storage system and then using ArcMap (GIS-Software) to provide representative results as maps. Karbala Province (Iraq) is the study area used here

    Potential use of UTES in Babylon Governorate, Iraq2020In: Groundwater for Sustainable Development, ISSN 2352-801X, Vol. 10, article id 100283Article in journal (Refereed)
    Abstract [en]

    There is a global attention that the future energy systems will be based on renewable energy like solar and wind. The large-scale utilization of renewables in space heating and cooling requires large Thermal Energy Storage TES to overcome the varying supply and demand. The process of producing the best Underground Thermal Energy Storage UTES system pass through two steps: first, finding the best type of UTES system, second, finding the best locations to install UTES system. Both of these two steps depend extremely on the site specific parameters such that the depth to the groundwater, transmissivity, type of soil, the depth to the bedrock, and seepage velocity. The purpose of this paper is to explain some of the site specific parameters that the type of UTES-system depends on and explain the suitable type of UTES systems. This study considers Babylon province (Iraq) as study area. This province has electricity deficiency due to Heating Ventilating and Air Conditioning HVAC applications. The methodology of this study includes reviewing the literature that consider the study area, and using Arc Map/GIS to visualize some of the in-site parameters. The results indicate that the best type of UTES system for the considered region is either aquifer or pit type, due to the type of the soil and the depth to the crystalline bedrock. The hydraulic conductivity and the seepage velocity in the considered region are (0.0023–2.5) m/d and (1.3 × 10−6 – 3.45 × 10−3) m/d respectively. These conditions satisfy the standards which regard aquifer type.

    Possibilities of reducing energy consumption by Optimization of Ground Source Heat Pump Systems in Babylon, Iraq2016In: Engineering, ISSN 1947-3931, E-ISSN 1947-394X, Vol. 8, no 3, p. 130-139Article in journal (Refereed)
    Abstract [en]

    Iraq is located in the Middle East with an area that reaches 437072 km2 and a population of about 36 million. This country is suffering from severe electricity shortage problems which are expected to increase with time. In this research, an attempt is made to minimize this problem by combining the borehole thermal energy storage (BTES) with a heat pump, the indoor temperature of a residential building or other facility may be increased or reduced beyond the temperature interval of the heat carrier fluid.Due to the relatively high ground temperature in Middle Eastern countries, the Seasonal thermal energy storages (STES) and Ground Source Heat Pump (GSHP) systems have a remarkable potential, partly because the reduced thermal losses from the underground storage and the expected high COP (ratio of thermal energy gain to required driving energy (electricity)) of a heat pump, partly because of the potential for using STES directly for heating and cooling. In this research, groundwater conditions of Babylon city in Iraq were investigated to evaluate the possibility of using GSHP to reduce energy consumption. It is believed that such system will reduce consumed energy by about 60%.
