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

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 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.
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 obtained results by hydrogeological and Tectonic survey related to fresh water resources in Al-Sin Basin, indicated that the fundamental aquifer of underground water in AL-SIN region belong to Jurassic. The alimentary basin of Al-Sin spring depen d upon filtration of rainfall water and snow throw Jurassic formation from north and north–east of basin. Direction of underground water circulation is toward west and south-west where we find flow place of Al-Sin spring and submarine fresh springs near seashore. Tectonical study shows the existence of fractures and fault groups with NE-SW, ENE-WSW and NW-SE directions. Groundwater movement has the same direction of fractures and faults NE-SW to ENE-WSW and Al-Sin fault structure which allow the existence of direct relation between principal Jurassic aquifer and secondary aquifer especially Cenomanian one.
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)
