The studied area is a part of the Tartous city, it is Syrian city on the coast of the Mediterranean Sea, the coast covers about 90 km from north Lebanon borders to Alsen river in the south .It is the most important port on the coast of the Mediterranean Sea in Syria .It locates about 100 km of the south of Latakia city. We study both Shb at line and the first part of the second pipe line, the first part of the second pipe line lengths from Auben station to Barmaia station, between , latitude in the north of the equator, and , longitude in the east of the Greenwich.Ductile iron pipes are used in this project, diameter 300mm and pumping 350m3/h. For protection of water hammer we use check valves,air valves ,and we use safe factor (1.5) when calculating expected pressures in the used pipes. We use a device called protection device of water hammer (40)bar, where installed out the station on the pumping line .Shb at line located in Drekiesh city, itis a Syrian city and fars 35 km from Tartous.it located on mountain high about 550 m from sea surface .It length from Shb at station to Almalagah station between , latitude in the north of the equator, and , longitude in the east of the Greenwich .This project aims to support the villages of Alalagah, and pumping 70m3/h. Ductile iron pipes and poly ethylene pipes are used in this prpject, For protection of water hammer we use check valves,air valves, and we use safe factor (1.5) when calculating expected pressures in the used pipes. We use a device called protection device of water hammer (25)bar, where installed out the station on the pumping line .The research aims to model both Shb at line and the first part of the second pipe line at the steady state, and study water hammer problem caused by pump failure and determine the maximum pressures in this two lines and suggest suitable procedures and methods to avoid it. The research also aims to use the soft ware in water networks studies because solving the equations of water hammer with hand methods is very difficult and more time, this what safe using like software. 409348049834422036788935409348049834422036788935 3We depend on the graphs and profiles to this two lines and determine some necessary points in modeling ,but not exist on this graphs by GPS ,like elevation of some valves at station and tanks .We take the reading of flow device and the result is true and equal to design flow 70m3/h .We depend on Water CAD V8 XM Edition program that allow to analysis this lines at steady state and calculate pressure values in this case ,we also use HAMMER V8 XM Edition that model water hammer. We also make some scenarios for some protection devices and its effect on pressures values then select the best one. Due to the results argument, we reach the following conclusions and recommendations Conclusions 1-There is no risk to both Shbat line and the first part of the second pipe line at steadyflow.2-Occurring pump failure in the first part of the second pipe line cause high pressures, which pipe line cant not resistant it. this pressures is higher than Pipe pressures, especially in the part which is near the pump.3-Check valve only protects pump and near equipments but did not protect the other part of the line .4-Using polyethylene pipes in the first part of the second pipe line ,reduce the pressures because of high elastic ,that observe the pressures wave.5-Using surge tank in the fourth scenario keeps the pressures at steady state and prevents any increase in pressures.6-When we makes many scenarios for some protection devices from water hammer , we know that surge tank is the best scenario for protection from water hammer.7-Occurring pump failure in Shbat line cause high pressures, especially in the part which is near the pump but less than pipes and equipment spressures ,so it is not necessary to use any protection device.Recommendations1-Necessaryof water networks and pumping line study at steady state ,using Water CAD V8 XM Edition because of its strong abilities whether in entering data or analysis results in forms of tables and graphs .2-Necessary of making detailed water networks study for water hammer before beginning design any pumping line or water network or by the time of design stage, using Bentley HAMMER V8 XM Edition program. watercad23-Necessary of making many scenarios for some water hammer protection device(surge tank-air vessels-rupture disks-change pipe materials..........)and select the best one.4-Spreat out software in water networks study because it safes a lots of time and work that can be made during solving it with hand methods.
