AlSin Spring spurts at the foot of coastal mountains and pours in The Mediterranean sea near Arab-Almulk village. Presently, spring water used for drinking, irrigation and industry, while excess water goes to sea. Current research aims to determine the daily discharge response to daily rainfall, and to set an equation for recession discharge for predicting spring discharge and volumes of flow after definite time from the beginning of spring base flow, which allows to operate and manipulate available water resources through an optimum design of water intake from this spring. Response time of AlSin Spring between (3-5) days for average discrete daily rainfall with high intensity which caused 0.5 ~ 1.0 m3/sec increasing in spring discharge value. Yearly discharge trends to decrease with a rate of 0.0975 m3/sec between 1974 and 2016 years. While the monthly minimum discharges increase about 0.1284 m3/sec, and monthly maximums decrease about 0.0752 m3/sec between 1994 and 2016. We recommend adopting recession curve analysis to predict the optimal discharge of springs within definite periods.

Research summary
يتناول البحث تحليل هيدروغراف الجريان القاعدي لنبع السن في الساحل السوري، الذي يُستخدم مياهه لأغراض الشرب والري والصناعة. يهدف البحث إلى تحديد مدى استجابة غزارة النبع اليومية للهطولات المطرية اليومية، وإيجاد معادلة تصريف الاتحسار للتنبؤ بمعدلات تصريف النبع وحجوم الجريان بعد أي زمن محدد من بداية الجريان القاعدي. تتراوح استجابة غزارة نبع السن اليومية بين 3-5 أيام للهطولات المطرية اليومية المتقطعة والمتوسطة والغزيرة الشدة، مما يسبب زيادة في غزارة النبع تتراوح بين 0.5-1.0 م³/ثا. يميل التصريف السنوي للنبع إلى الانخفاض بمعدل 0.0975 م³/ثا خلال الفترة من 1974 إلى 2016، بينما تزداد التصاريف الشهرية الأصغرية بمقدار 0.1284 م³/ثا خلال الفترة من 1994 إلى 2016، وتتخفض التصاريف الشهرية الأعظمية بمقدار 0.0752 م³/ثا. يوصي البحث باعتماد تحليل منحنيات الاتحسار للتنبؤ بالتصريف الأمثل للينابيع خلال أزمنة محددة.
Critical review
دراسة نقدية: يقدم البحث تحليلاً شاملاً لهيدروغراف الجريان القاعدي لنبع السن، ويعتمد على بيانات طويلة الأمد مما يعزز من دقة النتائج. ومع ذلك، يمكن توجيه بعض الانتقادات البناءة. أولاً، قد يكون من المفيد تضمين تحليل أعمق لتأثير التغيرات المناخية على غزارة النبع، خاصة في ظل التغيرات المناخية العالمية. ثانياً، يمكن تحسين البحث من خلال تقديم توصيات عملية أكثر وضوحاً لإدارة الموارد المائية بناءً على النتائج المستخلصة. أخيراً، قد يكون من المفيد إجراء مقارنات مع ينابيع أخرى في المنطقة لتعزيز فهم السياق الجغرافي والجيولوجي لنبع السن.

The study and design of water-intakes on springs is based on the analysis of time series of historical measurements to achieve prediction of incoming water volumes or future expected. The research aims to model the monthly water flows of AL-SIN Sp ring in Syrian Coast and future expectations of these flows, by adopting the Box-Jenkins models to analyze the time series data, due to its reliable accuracy. Monthly water flows, thus, monthly volumes, for 101 month (from June 2008 to October 2016) were processed. Performing the stability of the time series on variance and median and non-seasonality and making the wanted tests on model residuals, we found that the best model to represent the data is SARIMA(2,0,1) (2,1,0)12 , and after dividing the data into 81 month to build the model and 20 month to test it. Depending on the smallest of weighted mean of criteria RMSE, MAP, MAE,. The best predicted model was SARIMA (3,1,0) (1,1,0)12 and the model gave the nearest predicted values to actually measured data in spring.
The research area is located in the Syrian coast between the Sin and Rous river. This research aims at studying the hydrogeological characteristics of the unconfined aquifer in the research area and evaluating the conditions of its placed. The rese arch was based on a monitoring network consisting of 36 wells that penetrate the unconfined aquifer, and measurements continued during the period (October 2016 until September 2017). The unconfined groundwater depths in the research area range between 0.5-11.5 m, and sometimes during the drought period reach to 13.5 m, while it is close to the surface in the winter and up to 0.1m in some wells. The electrical conductivity ranges between 550-3700 μs/cm, increasing as we go west and reaching 9,000 μs/cm and more in the wells near the sea during the dry period. Groundwater levels Lower in the dry period to below sea level in near-shore wells, achieves the hydrodynamic conditions of the seawater intrusion.
Results of this research which had been done by hydrogeological and geoelectrical survey for fresh water resources in the study region (wells and springs) show that the fundamental aquifer of underground water in AL-SIN region belongs to Jurassic. Th e alimentary basin of AL-SIN spring depend upon filtration of rain water and snow throw Jurassic formation from north and north–east of basin. Direction of underground water circulation on west and south-west where we find flow place of AL-SIN spring and submarine springs near seashore.
The study and design of water dams depend essential on prediction of water volumes or future predicted in rivers, by using the time series analysis of the historical measurements. The research aims to make statistical study of monthly water volume s incoming in AL-Aroos River in Syrian coastal and future prediction of these volumes. And the Box-Jenkins models is adopt to analysis the time series data, because of its high accuracy. We attend the monthly water volumes for 15 years. And after doing the wanted tests on model residuals we found that the best model to represent the data is SARIMA(0,1,2) (1,2,1)12 , and after dividing the data to 14 years to build the model and one year to test it , and depending on the smallest of weighted mean of criteria RMSE, MAP, MAE,. The best predicted model is SARIMA (1,1,0) (0,1,1)12 and the model give the nearest predicted of measured data actually.
This study has been conducted on Syrian coastal area in 2013 season, aimed to analyze the cost of honey production and Farm income `at the Apiaries level, in addition to measure its net returns and economic efficiency. A field questioner was applie d to obtain elementary data of a random sample consisted of (304) of Apiary units. The results show that beekeeping is one of the economically viable agricultural projects, where most of the apiaries in the sample were able to achieve a positive net return as much, on average, about (405 834) SP / promiscuous, while its value was estimated at the hive level by about (7120) SP. It was found that the majority of apiaries in the study sample (87.8%) were able to achieve positive earnings, While the ratio (12.2%) exposed of the loss, and realized negative revenues . The results of the investment evaluation and financial analysis showed to the economic efficiency of the apiaries , reaching gross margin of the hive (11237.5) SP/year, and ratio of costs to revenue (62.9%), the profit ratio to total costs (59%), and general economic efficiency (1.59 ), and the Payback period (1.69) years.
