This study includes the evaluation of the problem of seawater intrusion in Al-Bassa area in 2014 through chemical monitoring of a group of sampling wells, under certain condition that were subjected to the area during the research, representing by rainfall precipitation in the study area was only 500 mm/ year, as a result in the suspension of irrigation from 16 October lake and reuse of many abandoned pumping wells. This study founds an increasing in the salinity values in the Al- Bassa coastal area of summer in 2014, ranging between(665.6-6432mg/l)after increasing daily pumping rates, in addition to the increasing of chloride and sodium concentrations in most of sampling wells water in conjunction with high salinity levels. In the fall, the salinity values ranged between 490-950 mg / l. The geochemistry of Na/Cl indicates values less than 0.84 in most water samples during the summer, while in autumn this percentage was higher than 0.84 in most samples ,to be an indicator for marine water.

Research summary
يتناول هذا البحث مشكلة تداخل مياه البحر مع المياه الجوفية في منطقة البصة الساحلية لعام 2014، حيث تم استخدام الرصد الكيميائي لتقييم هذه المشكلة. تم جمع عينات من 26 بئراً موزعة بين المناطق السكنية والزراعية، وتم تحليلها خلال فصلي الصيف والخريف. أظهرت النتائج ارتفاعاً في ملوحة المياه خلال فصل الصيف بسبب زيادة معدلات الضخ اليومي، مما أدى إلى ارتفاع تركيز الكلور والصوديوم في المياه. في فصل الخريف، انخفضت قيم الملوحة نتيجة لزيادة الهطول المطري وتوقف عمليات الضخ. تشير النسبة الجيوكيميائية Na/Cl إلى وجود تأثير لمياه البحر في معظم العينات خلال فصل الصيف، بينما كانت النسبة أعلى في الخريف مما يدل على تراجع تأثير مياه البحر. توصي الدراسة بإجراء دراسات دورية لحماية الموارد المائية في المناطق الساحلية، وتحسين شبكات الري للاستفادة من مياه الأمطار في مواسم الجفاف.
Critical review

Questions related to the research
  1. ما هي الأسباب الرئيسية لتداخل مياه البحر مع المياه الجوفية في منطقة البصة الساحلية؟

    الأسباب الرئيسية تشمل زيادة معدلات الضخ اليومي للمياه الجوفية، وانخفاض الهطول المطري، وإعادة استخدام الآبار المهجورة.

  2. كيف تم تقييم ملوحة المياه الجوفية في الدراسة؟

    تم تقييم ملوحة المياه الجوفية من خلال قياس الناقلية الكهربائية وتحليل تركيز الكلور والصوديوم في عينات المياه المأخوذة من الآبار.

  3. ما هي التوصيات التي قدمتها الدراسة لحماية الموارد المائية في المنطقة؟

    توصي الدراسة بإجراء دراسات دورية لحماية الموارد المائية، وتحسين شبكات الري للاستفادة من مياه الأمطار في مواسم الجفاف.

  4. ما هو تأثير تداخل مياه البحر على صلاحية المياه الجوفية للاستخدامات البشرية والزراعية؟

    تداخل مياه البحر يؤدي إلى ارتفاع ملوحة المياه الجوفية، مما يجعلها غير صالحة للشرب والري حسب المعايير السورية.

Fresh water shortage problem is the most important difficulty that counters agricultural and industrial improvement strategies on both Arabic and international levels, where Arabian region extends along vast arid and semi- arid areas, and mostly la cks for fresh water resources. Therefore, desalination choice has become an inevitable option to compesate deficiency of water, especially with the long Arabian costal line, where desalinated seawater is considered renewable fresh water resource. However, desalination mechanism requires water pretreatment procedures in order to reduce total hardness and pH values, to prevent salts precipitations which hinder thermal and membrane techniques.
This paper investigates the proximate analysis of zooplankton and the jellyfish Catostylus perezi through studying the content of proteins, lipids and carbohydrates (as glucose) in three different stations of Al-Khobar coastal area (Saudi Arabia) during four seasons. Physical and chemical factors of water, specific composition, abundance and biomass of zooplankton were also studied. The results indicate clear temporal and spatial differences in the content of organic matter of zooplankton. Proteins values were between 118.8 and 439.7 mg/g and lipids values were between below detection levels and 55.2 mg/g; whereas carbohydrates values ranged between 0.035 and 0.371 mg/g as dry weight. The results indicate clear differences in the content of organic matter of the jellyfish parts especially the medusa.
The research mainaim is Mapping of Groundwater Vulnerability to Contamination Using (PI) Method toevaluatethe study area (Marqieh and Alhousen watershed ) in Tartous governorate. The area of study forms a part of the coast basin, on the east coast of the Mediterranean Sea, located north of the Tartous governorate between , 34 5000,35 1000latitude in the north of the equator, and , 35 5000,36 2000 longitude in the east of the Greenwicharea covers about 700 Km2. The PI method is a GIS-based approach(We use ARCGIS .10 and the tool : Spatial Analyst Tools) , and gives special methodological tools for karstic aquifer , geological conditions , climate , relief , land use , all these conditions are mapped separately as individual maps and then integrated to achieve the groundwater vulnerability map. all the maps related to the study area was created in digital form and apply analysis processes to create vulnerability map which is a map divided to the fields and every field represents the possibility of contamination of groundwater in this region, whether high or low . The results obtainedfrom this study indicate that about 41% of the study area is under high groundwater vulnerability, 59% is under moderate, low and very low vulnerability.
This research was performed to study the effect of sewage water on the surface water of the Addelbeh Valley stream, and groundwater on both sides of the stream in Tartous Cement Factory area. Water samples were taken from the factory water outlet and Addelbeh Valley water to study the content of pollutants. We also took groundwater samples from selected wells on both sides of the waterway in the studied area. We repeated that process every two months for a full hydrological cycle from July 2013 to May 2014. We found a great increase in content of the industrial drainage water include oils and heavy metals especially iron, copper and zinc. For example: iron concentration in sewage water exceeded 150 mg/l in all samples. Besides sewage water and stream water contained high concentrations of ammonia and nitrite versus low concentration of nitrate, unlike water wells samples. The study revealed increased EC and salts concentration markedly in wells water due to its adjacency to the sea.
Proven chemical analyzes conducted in the summer of 2014 to thirty wells in the village AL-Shamia- Latakia region, that water wells west of the adjacent village to the seaside up to 300 m distance to the east where the salinity increases while decreasing the East Village to become water sweet near way of Lattakia-Kassab, at a distance of 1500 m fromn the sea beach.
