Good predictions can lead to significant benefits, however.
By supplying users directly with surface water rather than ground water, they vacated reservoir capacity for future inflows, saving over a million dollars in pumping costs and avoiding further drawdown of the regional aquifer. Hydrologic systems are inherently nonlinear because they involve feedback among subsystems that are themselves nonlinear. In the past, limited computer resources and lack of spatially distributed data at sufficient spatial and temporal scales have made it impossible to simulate coupled hydrologic systems at scales fine enough to be confident of the accuracy of underlying physical theories. Moreover, data about hydrologic systems have usually been limited to only a few samples, even though Earth systems exhibit considerable heterogeneity in both space and time.
