Developing Hydraulic Model of Water Distribution Network in Rafidia Area, Nablus by Abeer Melhim Noor Saleh Supervisor Dr.Mohmmad Almasri
2
Objectives of the project
To estimate the per capita water consumption of zone w0 of Rafedia. . To hydraulically analyze the WDN of Rafedia W0 zone using EPANET. . To propose design of the new WDN.
3
Study area Location: Topography:
Study area is Rafidia zone W0, which is located in Nablus. Topography: Height ranges between from 440m and 510m.
4
Study area Population of Nablus 126,000 persons.
Population of Rafidia 7,000 persons. Population of W0 is 3,500 persons.
