Description

A supply-side optimization model determines optimal strategies to convey water from all water sources and types to all water demand types, through both local distribution and national transfer lines. Developed to support the Jordanian National Water Master Plan (NWMP), objectives are minimizing unsatisfied demand or economic impact of unsatisfied demand, with or without using national water allocation priorities. The model is designed to use data contained within the dynamic NWMP. The model is applied to a pseudo-hypothetical system (HJ61H) provided by the Ministry of Water and Irrigation (MWI). System HJ61H embodies all types of anticipated situations and constraints. Test scenarios are: 1) minimizing un-weighted/un-prioritized unsatisfied demand, 2) minimizing unsatisfied demand while satisfying national priorities (from highest to lowest priority these are municipal, industrial, touristic, and agricultural); and 3) minimizing net economic impact of unsatisfied demand. Two multi-year stress periods are used. Constraints and bounds maintain acceptable volume balances for all individual and group flows from sources, thru conveyance systems, to demands. Water balancing units are national governorates. Water can be conveyed within and between governorates. For HJ61H all objective types yield the same objective function value. However, the un-weighted un-prioritized optimization have much more unsatisfied municipal demand than the prioritized optimization. For the employed average economic loss coefficients, minimizing economic impacts yields the same strategy (distribution of delivered water and unsatisfied demand) as prioritized optimization. Employing actual economic loss coefficients for each demand or adding groundwater drawdown constraints can cause different results.
