An inquiry is made into the valué of outputs as defined by the model of standard welfare economics. Application of this model implies that each investment project or installatíon should be viewed as a production process-a process consuming inputs and producing outputs. This notion is essential for efficiency analysis because, typically, both the inputs and the outputs have a social valué. The task of economic analysis is to determine if the valué of the outputs produced by an undertaking exceeds the valué of the inputs. Only if gains exceed costs is the undertaking judged efficient.'

Of the remaining amount, polar ice and glaciers account for 2.24 percent, saline lakes and inland seas for 0.008 percent, and the atmosphere for 0.0001 percent. Subsurface water more than a half-mile deep accounts for 0.31 percent. This means that the fresh water that is actually available amounts to only 0.3169 percent of the earth's total water .1). This total is distributed very unevenly on and under the earth's surface and over time. These factors, combined with the many open-ended subcycles of the global hydrologic cycle, account for many of the water resources problems facing water resources planners and managers.
