Résumé partiel
Utah, located in the arid southwest, is a state that experience s chronic water shortages. The pattern of valleys and high mountain ranges that exists in the state produces sharply contrasting differences in climatic conditions . Desert valleys in the western portion may receive as few a s 4 inches of precipitation in a year while headwater areas in the Wasatch Mountains receive 60 inches or more. Wide cyclic as well a s geographical variations of precipitation added to uneven seasonal distribution makes development and efficient utilization of water resource s vital though difficult. In order to make the most effective distribution and use of this precious water resource, the State of Utah is engaged in the preparation of a State Water Plan . The Utah Division of Water Resources, designated by the Utah Legislature to accept prime responsibility in this task, is cooperating with universities and other government agencies in this effort. As a basis f or planning and further development, an assessment of available water resources and the current stage of development is essential . To facilitate this assessment the area of the state has been divided geographically into several hydrologic study areas and sub-areas , shown in Figure 1. The Division of Water Resources, the U.S. Geological Survey , the Utah Water Research Laboratory, and other organizations are cooperating in making hydrologic studies and reports for these areas . To provide for uniformity in this state -wide effort, the following general procedures have been established : 1. Review existing land use data for each hydrologic area and determine their adequacy for meeting the needs of the water planning program . 2. Conduct field land-us e surveys for those areas where inadequate information is available in order to delineate the various land use categories f or each hydrologic area and sub-area. Summarize the acreage data for use in the water budget studies . 3 . For each sub-area, determine t he quantity and quality of runoff . Also, assemble and prepare for computer processing relevant available data regarding the hydrology and climate of each area, together with appropriate maps and charts . 4 . Investigate relationships between precipitation and runoff with respect to both time and space . In this regard, factors influencing runoff, such as physiography, geology , vegetative cover, slope, elevation, and aspect are evaluated . 5 . Estimate all major depletions from the flow system of the area . 6 . Prepare water budgets which account for the time and spatial distribution of the total water.
