<br />000971 <br /> <br />~~~~k~~ <br />~t:,:i$~J <br /> <br />Application Analysis--Water Supply and Requirements <br /> <br /> <br />Because the entire atmospheric water resources effort is aimed at <br /> <br /> <br />providing the proficiency to furnish additional water supplies through- <br /> <br /> <br />out the Nation in answer to increasing needs, the needs must be <br /> <br /> <br />analyzed. <br /> <br />This part of the program considers analyzing the two aspects of <br /> <br /> <br />atmospheric water supply: water supplied directly to the surface <br /> <br /> <br />and the immediate soil and groundwater reservoirs for use in the <br /> <br /> <br />near vicinity; and water contributed by runoff and major ground- <br /> <br /> <br />water sources which furnish water to streams, lakes, rivers, and <br /> <br /> <br />extensions of these systems. <br /> <br /> <br />The ability to increase runoff water supplies will be the initial <br /> <br /> <br />program goal for these reasons: the orographic mechanism, which <br /> <br /> <br />will first be utilized to augment precipitation, is particularly sig- <br /> <br /> <br />nificant in producing runoff, as shown by comparing Figures 6 <br /> <br /> <br />and 7; and the water usage from runoff is often significant in the <br /> <br /> <br />areas of most serious water needs, as illustrated by the relation- <br /> <br /> <br />ships between Figures I, 7 and 8. <br /> <br />.~...~w~~...~."i': <br />~~~~[~~~ <br /> <br /> <br />~F.~-'.}__.-.~..:.o: <br />"_;:'f-~.,.<.:;:~:,:-.:~_~ <br /> <br />Water deficiency regions where projected requirements exceed the <br />fully developed natural supply are shown in Figure 1.
