Abstract

ABSTRACT Estimating the physical properties of water-bearing layers is an essential part ofgroundwater studies. One of the most effective ways of determining these properties is toconduct and analyze aquifer tests. The aim of this research is to carry out hydrogeologicalinvestigation in Khanaqin basin within Diyala Governorate in the east of Iraq to calculatehydraulic parameters of the most important product groundwater aquifers. Cooper-Jacoband Theis Recovery test methods were used to calculate transmissivity and storagecoefficient after field investigation of aquifers extended in the basin. The geographicalposition, elevations, static water levels, depths, thicknesses and maximum yields werecarried out during field work. The results showed that Khanaqin basin has two geologicalunits represented by unconfined and confined aquifers, where (4) wells were used inpumping test. The average transmissivity parameter was ranged between (273-4590m2/day) in unconfined aquifer while this range was (14.47-244.35 m2/day) in confinedaquifer. Transmissivity contour map indicated increasing value of this parameter towardsnorthern west direction of the Khanaqin basin. Storage coefficient ranged between(3.5*10-5) to (1.14*10-3). The increasing of transmissivity parameter as groundwatermovement generally flow towards the northern west leading to increase groundwaterdischarge from wells penetrate unconfined and confined aquifers

Abstract

Climate and hydrological conditions in any hydrological basin are multi-combined reflection of natural factors of morphology and soil nature, as well as the changing in climate factors that affect directly on hydrological cycle. Water balance techniques are a means of solution of important theoretical and practical hydrological problems, while estimating the physical properties of water-bearing layers is an essential part of groundwater studies. One of the most effective ways of determining these properties is to conduct and analyze aquifer tests. The aim of this research is to compare groundwater recharge in Khan Al-Baghdadi area which located to northwest of Anbar governorate in the west of Iraq, depending on meteorological water balance and calculated hydraulic parameters of groundwater aquifers in order to predict the suitable methods to determine groundwater recharge. Geographical position, elevations, static water levels, depths, thicknesses and maximum yields were carried out during field work. Meteorological parameters of Hit station during the period (1995-2010) was used to calculate water surplus using Thorntwaite formula, while cooper-Jacob and Theis recovery solutions were used to calculate transmissivity and storage coefficient. The result indicate that water surplus was (16.71) mm. divided into (10.13) mm as runoff and (6.58) mm as groundwater recharge. The average annual of groundwater recharge in the area was (41.38) million cubic meters depending on water balance technique, while annual groundwater recharge calculated based hydraulic parameter was (41.51) million cubic meters.

ان الظروف المناخية والهيدرولوجية في أي حوض هيدرولوجي هي انعكاس مشترك ومتعدد للعوامل الطبيعية للاشكال الارضية وطبيعة التربة بالاضافة الى التغير في العوامل المناخية التي تؤثر بصورة مباشرة على الدورة الهيدرولوجية. تعد تقنيات استخدام الموازنة المائية وسيلة لحل المشاكل الهيدرولوجية النظرية والعملية المهمة ، في حين أن تخمين الخصائص الفيزيائية للطبقات الحاملة للمياه يعتبر جزء أساسي من دراسات المياه الجوفية. ان واحدة من أكثر الطرق فعالية لتحديد هذه الخصائص هو إجراء وتحليل اختبارات مكامن المياه الجوفية حيث ان الهدف من هذا البحث هو مقارنة تغذية المياه الجوفية في منطقة خان البغدادي التي تقع إلى الشمال الغربي من محافظة الأنبار في غرب العراق بالاعتماد على تقنية الموازنة المائية المناخية والمعاملات الهيدروليكية المحسوبة لمكامن المياه الجوفية من أجل التنبؤ بالطريقة المناسبة لتحديد مستويات هذه التغذية. تضمنت الدراسة الحقلية للمنطقة تحديد الموقع الجغرافي والارتفاع ومناسيب المياه الجوفية الثابتة والأعماق وسمك المكمن الجوفي بالاضافة الى انتاجية الابار. تم الاعتماد على البيانات المناخية المسجلة لمحطة انواء هيت خلال الفترة (1995- 2010) لحساب الفائض المائي باستخدام طريقة ثورنتوايت، في حين تم استخدام طريقتي كوبر - جاكوب وثايس لعودة المنسوب لغرض تحليل بيانات الابار وحساب معاملي الناقلية والخزن. اشارت النتائج إلى أن الفائض المائي بلغ (16.71) ملم موزع إلى (10.13) ملم جريان سطحي و(6.58) ملم تغذية للمياه الجوفية . بلغ المعدل السنوي لتغذية المياه الجوفية في المنطقة بحدود (41.38) مليون متر مكعب اعتمادا على تقنية الموازنة المائية فيما بلغ معدل هذه التغذية المحسوبة بالاعتماد على المعاملات الهيدروليكية بحدود (41.51) مليون متر مكعب.

Abstract

The mainly objective of groundwater studies is assessment the physicalcharacterizations of water-bearing layers. Conducting and analyzing aquifertests is one of the most efficient ways to assessment these characterizations. Theaim of this research is to carry out hydrogeological investigation in Khan AlBaghdadiarea within Anbar Governorate in the west of Iraq to evaluatehydraulic properties of the most important groundwater aquifers in order toachieve optimum use of groundwater in term of sustainable water management byusing Cooper-Jacob and Theis Recovery Test methods to calculate transmissivityand storage coefficient after field investigation of aquifers extended in the areawhere geographical position, elevations, static water levels, depths, thicknessesand maximum yields were carried out. The results showed that Khan Al-Baghdadiarea has only confined aquifer within the geological formation extended in area.The average transmissivity and storage coefficient parameters, which calculatedusing two wells, drilled in the area were (33.966-1171) m2/day and (2.2*10-4-2.07*10-2) respectively, dependent on cooper-Jacob and Theis recovery solutions.Transmissivity distribution contour map showed increased values towardssouthwest part of the area while gradually decreased values was recorded in theeastern and southeast part of the area.
