in australia craig estimated this loss to be about of the total storage volume this evaporative loss could increase by about by due to the effect of higher surface temperatures in the face of climate change heifer lemckert and zhang increasing total usable water storage by reducing this type of loss depends on the adoption of evaporation suppression technology which is driven by the marginal value product of the water to be saved this can be further split into recoverable seepage that infiltrates freshwater aquifers as return flows as well as the nonrecoverable seepage infiltrating a saline aquifer
