Taking the example shown in figure 1, S1 and S2 represent divers(prenominal) water lineages with different supply size (m3/day). Each source has different locations and elevations according to the grid information provided by the real world system. 3- Demand areas The demand area represents a appeal of adjacent demand cells with the same...If you want to get a secure essay, order it on our website: OrderEssay.net
