تشكل منطقة البحث جزءاً من حوض الساحل على الساحل الشرقي للبحر المتوسط، و تقع شمال مدينة طرطوس. يحدها من الغرب البحر المتوسط و من الشمال أنهار(جوبر–بانياس–الباصية) و من الجنوب نهر الحصين، و تبلغ مساحة منطقة البحث حوالى 358km2. يهدف البحث إلى إيجاد علاقة تربط بين قيم الهطل المطري و الجريان ضمن حوض نهر مرقية، عن طريق إجراء دراسة إحصائية تحليلية لبيانات الهطل المطري و غزارة النهر باستخدام برنامج Minitab، مما يساعد في استكمال القياسات غير المتوفرة، و التنبؤ بقيم غزارة النهر تبعاً للهطولات المتوقعة في حوض النهر. و توصلت الدراسة إلى أن علاقة الهطل المطري بالغزارة في حوض النهر هي من الشكل: Q = 216 + 0.0379 P - 36.8ln(P) + 3.46 ln(Q)، و تعبّر قيم الهطل المطري ضمن الحوض عن 87.2% من التغيرات التي تطرأ على جريان النهر،و أوصت الدراسة بضرورة تكثيف قياسات تصاريف النهر بغية زيادة موثوقية بياناتها.
The studied area forms a part of the coastal basin on the east coast of the Mediterranean Sea located north of Tartous city.The area is bordered by the Mediterranean Sea from the west. And (jobar,banias, albasia) rivers from north, al Housen river from the south. The area covers about (358) km2. The research aims to find arelationship between rainfall and flow within Mrqiyeh River Basin, by conducting analytical statistical study using Minitab software, which helps in completing the measurements are not available, and to predict the river flows depending on the expected precipitation in the river basin. The study found that the relationship is:Q = 216 + 0.0379 P - 36.8ln (P) + 3.46ln(Q) ,and rainfall reflect 87.2% of the changes that occur to the flow of the river. The study recommended that need to intensify the river discharges measurements in order to increase the reliability of their data.

The importance of this study lies in the hydrological analysis of the
relationship between the drainage system and the precipitation. The
problem of the study reveals in the water incompetence in the basin
which get to 336 million m3 and will gets
to 600 million m3 with
probability (p = 50%) and associated with missing the accurate evaluation
of the water resources.
The study aims to evaluate the water resources in the basin, to create a
mathematical model for calculation of the run off and its relationship with
the precipitation, and to predict the water resources for the hydrological
year according to many probabilities and the complementary
management for water resources.
Stages of the study involve the following:
1- Determining of the active stations in the feeding of hydrometric
stations.
2- Observing the average of water resources quantity (precipitation) over
the basin that reached 9764 million m3 and range between 2,26millionm3 in the hydrometric station of AL- Hamidi and 112,42
million m3 in Hama station.
3- Observing the average of the run off in the basin reached 744,67542
million m3.
4- Observing the run off system in the basin is a snow-rain system, where
the average of maximum discharge associates with precipitation and the
minor discharge associates with deprivation of the precipitation.
5- Creating a mathematical model for calculation of the run off and its
relationship with the precipitation.
6- Predicting the water resources for the hydrological year according to
many probabilities.
7- Creating a water strategy for the basin according to the data of water
predication in many probabilities
River flows depend on precipitation in their catchments, where the flow is highly
correlated with precipitation, among many climatic and geographic factors. The
relationship between precipitation and runoff is of great importance in estimating flow
changes in The HWAIZ basin that is located between The-Zrod and The-Gelani basins.
The Al-HWAIZ Dam was built on the HWAIZ River with storage capacity of 16.5 MCM.
The purpose of this study is to find a relationship between rainfall and runoff in The
HWAIZ basin. This study depended on statistical analysis of rainfall and runoff data, and
the analytical study of the annual rainfall data (1959-2011), to guess the trend of rainfall
and its future changes and forecasting changes in the HWAIZ river flows. The study
showed that the runoff coefficient values ranged between (0.007-0.66). A mathematical
relationship was established that allows to estimate flow based on measured or predicted
precipitation values, as well as appraise missing or lacking data with accepted level of
accuracy.
The Alsafarqieh watershed is located on the western slopes of the coastal mountain range,
Its area is 132.58 km2, It forms a part of the Alros river basin, The river starts at a height of
1200 m, A group of tributaries meet and form the Alros River
, which flows into the
Mediterranean Sea. Salaheddin Dam was constructed to store 10 MCM on the riverbed at
the intersection of the Qurdaha River with the Shehada River. The study aims to determine
the rainfall- runoff relationship in The Alsafarqieh watershed. The solution depends on the
statistical analysis of precipitation and runoff data. Then the study found the mean annual
precipitation is 159.6 MCM/year, and the mean annual flow into the Salaheddin lake was
9.4 MCM during the study period (2010-2012), so the runoff coefficient is 0.06. This
indicates a significant water loss. A mathematical equation to predict the runoff quantities
depending on the values of precipitation, has been concluded. This is important to study
water projects for water storage and flood prevention.
Al-Kabeer River Coastal Plain faces very important economic activities which lead to growing water demands. This research aims to define the relationship between rainfall and subterranean-water levels. In the mountainous area fissured marl and limest
one with high permeability spread. However, on the coastal plateau deposits with moderate to low permeability values spread, and water levels quickly respond to rainfall and irrigation water, which makes it get easily polluted and affected by climatic factors. Analyses and discussions of field data have led to the fact that subterranean-water levels are to do with many natural and artificial interrelated parameters. And in some cases, they can be adversely oriented, and difficult to isolate and monitor separately, and become very difficult to derive mathematical formula for describing the relationship between just two parameters (subterranean-water percentages and rainfall levels)
Snobar River is the basic water resource system in Snobar watershed (268.8 km2), which empties into the Mediterranean sea 10 kilometers south of Lattakia. We must find out advanced management to face of the recent serious conflicts such as climate ch
anges. Modeling is adopted as appropriate tool to achieve this object. This study uses the software package WEAP21 (Water Evaluation and Planning System), which is specifically designed to evaluate and plan the water resources. We suggest two scenarios to carry out the weaping Snob arriver basin: the first includes new irrigation techniques, the second includes extended dry climate. The study has shown that demand site coverage reaches to 100%, but the river dries in the downstream of Athwart reservoir. We economize on water by suggestion a dripping irrigation technique (59%). Water year method and extended dry climate scenario declare the likely dangerous effects of climate changes.
