إنَّ تأمين مصادر ذات نوعية مقبولة لتغذیة المدینة بمياه الشرب لا یعني بالضرورة أنَّ هذه المياه ستحافظ على نوعيتها الجيدة ضمن شبكة التوزیع إلى حين وصولها للمستهلك، حيثُ یُمكن لنوعية مياه الشرب أن تتردَّى خلال مرحلة التوزیع لأسبابٍ عدیدة آمكوث المياه في الشبكة لمدة طویلة قبل وصولها للمستهلك (ركود المياه)، أو وقوع حادثة تلوث بأحد العناصر الضارة في مكانٍ ما من الشبكة، أو مجرَّد دخول مصادر جدیدة في الخدمة (ذات نوعية أدنى) للمساعدة في تغذیة الشبكة في أوقات الذروة.
Drinking water although acceptable in quality when it leaves the treatment plant or the supply source, it may undergo changes in quality during the distribution phase before it reaches the consumer. Changes in quality may be caused by chemical or biological transformation, by a loss of system integrity, or by blending of water from different sources.

In this research, we present, a linear programming using model.
This model can define the optimal proposal ( with minimum cost
and high efficiency ) in both cases : new net design or exist net
modification.
Alsin Spring is the most important water sources in Syrian coastal area, due to it is the source of drinking water for the main cities and towns in the Syrian coast. This research aimed to study some contaminant indicators in Alsin spring and some t
aps of distribution system of Alsin drinking water, and compare the Indicators with samples of bottled drinking water from Alsin spring and three other water sources (Drekish, Bukkeen, and Alfigeh). The study included determining the concentrations of nitrates, nitrites and some heavy metals including lead, cadmium and nickel in water samples. The results showed that all water sources contain varying concentrations of lead, while the nickel and cadmium were vary in drinking water samples; The concentrations of nickel and cadmium in some samples were low while were under the detection limits in other samples. The analysis of samples of bottled drinking water showed that the samples from Alfigeh spring were the lesser contamination with heavy metals, while the samples from Alsin spring were contain highest concentrations of lead and nickel. The samples of bottled water from Bukkeen spring contain the highest level of cadmium. The results showed that the concentrations of nitrate, nitrite and heavy metals differ depending on the water source. However, all these concentrations were lower and within the acceptable limits of Syrian standard for drinking water. The study concluded that water resources in the coastal area are distinguished with their higher pure.
Modelling the relationship between drinking water turbidity and other indicators of water
quality in Al-Sin drinking water purification plant using Dynamic Artificial neural
networks could help in the implementation of the stabilization for the per
formance of the
plant because these neural networks provide efficient tool to deal with the complex,
dynamic and non-linear nature of purification processes. They have the ability to response
to various instant changes in parameters influencing water purification.
In this research, four models of feed-forward back-propagation dynamic neural network
were designed to predict the effluent turbidity from Al-Sin drinking water purification
plant. The models were built based on turbidity, pH and conductivity of raw water data
while the effluent turbidity data were used for verify the performance accuracy of each
network. The results of this research confirm the ability of dynamic neural networks in
modeling and simulating the non-linearity behavior of water turbidity as well as to predict
its values. They can be used in Al-Sin drinking water purification plant in order to achieve
the stabilization of its performance.
Water sources in Syrian coastal area have a great importance due to the variety of the
sources and the urgent needs to water for drinking and irrigation. Therefore great efforts
are made to protect water sources from contaminants. This research aim
ed to study some
contaminant indicators in some drinking water sources in the Syrian coastal area. The
study included determining the concentrations of nitrates, nitrites and some heavy metals
including lead, cadmium and zinc in water samples taken from five sources of water
distributed from north Lattakia to north Tartous. The results showed that the concentrations
of nitrate, nitrite and heavy metals differ depending on the water source. However, all
these concentrations were lower and within the acceptable limits of Syrian standard for
drinking water. The study concluded that water resources in the coastal area are
distinguished with their relative purity and contaminants little reach.
The main goal of the presented research in this paper is to find a general way to solve longitudinal vibration problems. This way must solve these problems in nonlinear elastic bar systems with a biological factor.
We applied longitudinal vibration
equations in a nonlinear elastic bar with biological factor, the bar material was taken non-linear. and solve the problem in a bar of finite length.
