The research includes an analytical study of long term pumping test with observation wells to get the optimum determination of the most important hydrogeological parameters of confined aquifer in Banyas, by pumping from a well with average pumping rate 10104m3/day for 36 hours and only 5 hours of complete recovery groundwater level. This test is accompanied by measuring the variations of the groundwater levels in the monitoring wells. Analytical methods of steady- unsteady of groundwater flow are used to evaluate the long term pumping test, and then to determine the optimum evaluation. The Transmissivity of the confined aquifer is about 5000 m2/day (very high potential), and the storage coefficient is 1,8.10-4. Then they used to predict the groundwater drawdown during one day. So, we can get 20000 m3/day from the aquifer and the drawdown not more than 1,75 m as quasi-steady drawdown at distance 500 m from the pumping well.

This is a study of free groundwater level changes through time, and the level of its being affected by natural and artificial factors, which allows evaluating general water situation of the aquifer. This study shows that groundwater system in the stu dy area from the type of water division line (climatic system) connects in direct connection with infiltration from rainfalls in which the natural factors (recharge) play the main role in forming the system of groundwater, in addition to the artificial factors (irrigation), and these factors yield three periods of the obvious terminal changes of the levels in hydrologic year (descending, stability, ascending). However, groundwater is renewable because of stability in the situations of this water, and its discharge to hydrodynamic net of groundwater in Al-kabir al-shimali and Al-snobar rivers and in the Mediterranean Sea as well.
Fiber reinforced polymer (FRP) plates have gained popularity in the strengthening of reinforced concrete (RC) members due to the high strength to weight ratio, the ease of installation and low maintenance costs compared to other systems such as steel plates. Also, external bonding of fiber reinforced polymer (FRP) plate has been proven to be an effective method to strengthen and damage RC structures. However, not much attention has been given to the long-term behavioral aspects of FRP-strengthened RC members. It is difficult to accurately predict the long-term deflection, crack width and behavior of FRP-strengthened RC members. This study presents a method for predicting the deflections at any time of the service life of normal and high strength concrete structures, loaded at any age, creep coefficient and shrinkage strain and the participation of the compressive steel for RC beams, and for RC beams strengthened with FRP plates. The accurate prediction of deflections is a complex problem which requires the use of non-linear and time-dependent analytical methods. These methods are, in general, time consuming and require great effort[6-13]. However, at the design stage, simple but reliable methods which take into account the most important parameters influencing the long-term deflections may be very useful to adequately design the structure. For that purpose, many simplified methods have been developed [1-2-3-4-14]. Equations have been programmed to access the method combines the simplicity and accuracy and provides valuable information about the influence of each parameter on the increasing deflections with time. The analytical values are compared to the experimental results from some existing papers [8-9], and to the results obtained from ACI code [1]. It is found that the analytical method is in a good agreement with the experimental results from some existing papers [8-9].
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.

The third sector of lower Euphrates basin has a great economic importance, but some lands have gone out of service because of salinization due to the rise of groundwater levels. Thus, it is very important to solve the ground water issue using new s cientific techniques. This research aims to solve the drainage problem in the third sector using a scenario based on a mathematical model, the results of which allow us design a proper drainage network comprised of 111 wells scattered all over the study area, with a total abstraction of 269000 m3/day. This will lower the groundwater level, dry the swamps, and decrease the soil salinity, ensuring a sustainable economic exploitation of agricultural lands.
