Abstract: | A new approach for evaluating water sustainability is introduced by comparing physical and economic sustainability. To achieve
physical sustainability, water should be available in sufficient quantity and of good quality and used efficiently. The economic
sustainability can be achieved by balancing between costs and values of water. The objectives of this study were to estimate
the physical and economic sustainability of surface water in the Big Lost River, south–central Idaho. The study used a Bayesian
network by building a graphical diagram of nodes representing all significant variables related with the sustainability, such
as water demand, water quality, and the different costs and values of water. The study showed that the likelihood of the physical
sustainability is less than that of the economic sustainability, which is attributed to the scarcity of water in the Big Lost
River.
