performance of water supply networks under water hammer phenomenon based on sustainability coefficient (case study: feridonshahr water supply network)

Head-Driven Simulation of Water Supply Networks

Up to now most of the existing water supply network analyses have been based on demand-driven simulation models. These models assume that nodal outflows are fixed and are always available. However, this method of simulation neglects the pressure-dependent nature of demand that is characterized by changes in actual nodal outflows particularly during critical events like major mechanical or hydra...

Rural Water Supply Network

Optimizing Operations of Large Water Supply Networks - A Case Study

In this paper we propose a mathematical programming model for a large drinking water supply network and discuss some possible extensions. The proposed optimization model is of a real water distribution network, the largest water supply network in Flanders. The problem is nonlinear, nonconvex and involves some binary variables, making it belong to the class of NP-hard problems. We discuss a way ...

Sustainability Assessment Of National Rural Water Supply Program In Tanzania Abstract Sustainability of rural water supply programs in developing countries

Sustainability of rural water supply programs in developing countries is still an elusive goal. It is widely accepted that as a rule they have failed to deliver benefits to society in the long run. Emphasis has frequently been given on the short-term activities. Fast production of new schemes is thus a common strategy, prioritizing the engineering component, while sidestepping social and partic...

Calculation of Leakage in Water Supply Network Based on Blind Source Separation Theory

The economic and environmental losses due to serious leakage in the urban water supply network have increased the effort to control the water leakage. However, current methods for leakage estimation are inaccurate leading to the development of ineffective leakage controls. Therefore, this study proposes a method based on the blind source separation theory (BSS) to calculate the leakage of water...

Spatial distribution of water supply reliability and critical links of water supply to crucial water consumers under an earthquake

Observations from past earthquakes, such as the 1906 San Francisco earthquake, the 1994 Northridge earthquake, and the 1995 Hyogoken-Nanbu (Kobe) earthquake, have clearly demonstrated that compromising water supply systems after an earthquake not only impairs fire fighting capacity, but also disrupts residential, commercial, and industrial activities, and threatens the economic well-being, secu...
