ABSTRACTMuch research has been done to determine the benefit of a water resources development to society as a whole. Some research has explored the benefit of such a facility to a region. Very little research exists on the effects of a reservoir on the immediately surrounding area.The general hypothesis of this study is that the spatial patterns of land use change are influenced by economic characteristics of the reservoir and reservoir area. Several hypotheses concerning the effects of relative location on a peninsula are tested using analysis of variance. The data used for the analysis is based on Lake Cumberland, a reservoir in southern Kentucky.The analysis indicates that there exists significant patterns of land use change around the lake and on peninsulas.

摘要:

ABSTRACTPresent‐day climatic conditions of the Earth were reached between 5,000 and 8,000 years ago. These are essentially the conditions under which the earliest civilizations arose. Ancient basic water problems were the same as those of today, and remarkable technologies for coping with these problems were developed. Few water technologies, except for water treatment, are modern creations.Dry farming began about 8000 B.C. Irrigation began about 5000 B.C. and became extensive by about 3500 B.C., principally in Mesopotamia, the Nile Valley of Egypt, and the Indus Valley of Pakistan. Ancient irrigators developed ingenious structures for obtaining groundwater without the use of wells or sweeps. One device, the Khanat (a kind of infiltration gallery), is still widely used in the Mediterranean area, southwest Asia and China. The khanat was invented during the First Millenium B.C.Ancient peoples also learned to collect surface runoff in areas of scanty precipitation and to use it for local groundwater recharge. The water was recovered from dug wells and used for domestic supply and stock watering.Damming of rivers began at least by the early part of the First Millenium B.C. in the Arabian Peninsula. Most early dams were for irrigation but some were also for city water supply. Many canals in various areas served the dual purposes of water supply and navigation.Soil and water salinity have been persistent problems throughout the history of irrigation and we still have not solved these problems.Irrigation practices were developed independently in the New World but much later than in the Old. North American Indians in some areas still follow the ancient practices. The chinampa system, still used in Mexico, is one of the most intensive methods of farming ever devised.Ancient peoples in the Old World also developed ingenious methods for conserving and increasing soil moisture and for retarding runoff and erosion.During the time of classical Greece and imperial Rome practical water engineering developed to a high degree. Water tunnels, aqueducts, canals, drainage ditches, and dams become commonplace. Even so, water supply and management came relatively late in Europe, where dependence had been largely on natural supply and distribution until the 19th Centur

摘要:

ABSTRACTThe increasing need for water has increased interest in artificial recharge by water‐management agencies. An evaluation of current knowledge of processes and problems of artificial recharge indicates that a great deal of additional research is necessary before recharge feasibility can be evaluated in most situations. Experience in using recharge wells on the Southern High Plains of New Mexico and Texas indicates success when using good quality water, and failure when recharge water contains high concentrations of particulate matter. Surface spreading is a more suitable method when water has a high sediment content, but may not be feasible in some hydrogeologic situations. Theoretically, well construction is important to the success of injection recharge operations, but little experimental work exists to support this view. Results of recharge experiments on the Southern High Plains support these conclusion

ABSTRACTChanges in groundwater levels due to a well discharging at a constant rate are used with various formulas to determine hydraulic properties of aquifers and their confining bed and to detect the presence of aquifer boundaries. These formulas are generally solved by graphical methods.

摘要:

ABSTRACTThere are four groundwater resources to be managed: yield, storage capacity, water‐in‐storage, and transmissivity. Management concepts have changed over the years, with today's concept which covers comprehensive integrated use of the four groundwater resources with surface water resources to provide the most efficient water service for an area in terms of quantity, quality, and cost. Complete geologic and hydrologic understanding provides a base for formulation of plans which can utilize the techniques of artificial recharge, control of sea water intrusion, and variation of pumping patterns while protecting the resources through proper well construction and abandonment, placement of sanitary landfills, and liquid waste disposal.Plan formulation involves varying recharge and extraction amounts while maintaining the total of pumped groundwater and developed surface water equal to the projected and future demand. Physical limitations of the system must be recognized to assure reality of the plans. Legal constraints should not be placed on the plan formulation process. A present worth or other technique is used to provide an economic comparison among plans. Implementation will entail development of legal and organizational structure, with the most difficult problems relating to the management organization in terms of boundaries and pow
