Show ADEQUATE PROVISION FOR THE ESTABLISHMENT OF THE INTERRELATIONSHIP OF ALL FEATURES OF THE HYDROLOGIC CYCLE PROVISION IS MADE FOR THE UTILIZATION OF THE RESULTS OF RESEARCH AND OF COLLECTED DATA, BY OTHER FEDERAL AGENCIES There is no established responsibility for determining the relation between precipitation and either surface or subsurface water movements, and there is no satisfactory basis for quantitative comparisons between the two. Neither evaporation nor transpiration data have been developed to the point where they are adequate for calculating the amount of water consumed by useful plants nor the amounts wasted into the atmosphere through evaporation or transpiration. National water resources- data program.- The program makes adequate provision for the establishment of the interrelationship of all features of the hydrologic cycle. It provides a complete over- all accounting of the quantities of water resources involved in precipitation, its disposition through outward drainage, the quantities involved in each phase of evapotranspiration and any net changes in surface or subsurface storage. Both surface and subsurface flow and storage are considered as interrelated features. The program establishes a joint responsibility for the Weather Bureau and the Geological Survey to calculate and interpret the amounts of water and the basic conditions of all important hydrologic and other features needed for the most effective utilization of all water resources. The program establishes a complete accounting of the amount of water involved in each phase of the hydrologic cycle and the interpretations of the basic conditions governing its use. Provision is made for the utilization, wherever practicable, of the results of research and of collected data, carried on as the necessary part of programs by other Federal agencies engaged in the development or management of water resources. This will make unnecessary the duplication of such data- gathering and research programs by the Weather Bureau and the Geologic Survey. 30 |
