Show are given below for each of the main phases of resource development. Economic items which are common to all studies are population, price levels, and costs. These data are needed for all studies listed below and are not indicated individually for each one. Navigation.-Water and mineral resources, mining, manufacturing, transportation, agricultural production and markets, and industrial production and markets. Flood control.-Land, water, and mineral resources, mineral, and other industrial production, and flood damages, in small as well as large streams. Drainage.-Land and water resources, agriculture, agricultural and industrial production, and damages from improper drainage. Hydroelectric power.-Land, water, and mineral re- sources, mining and manufacturing, value of power markets and power in industry and other uses, and mineral and other industrial production. Irrigation.-Land, water, and mineral resources, agri- culture, power, agricultural markets, and agricultural production. Water supply.-All data on water and mineral re- sources, mining and manufacturing, power, industrial markets, and mineral and other industrial production. Pollution abatement.-Water resources, mining, manu- facturing, mineral, and other industrial production, costs of recovery of values. Recreation.-Land and water resources. Watershed management. Project Investigation and Specific Coverage After authorization of a project or program, the definite project investigation is prepared. This is based upon all of the data assembled for the preceding stages, with addi- tional specific coverage for those portions of the total area of concern in which more detailed investigations are ad- visable. Cadastral surveys are necessary for this stage. As a phase of surveying procedure, specific coverage required in each category of physical resources, is as follows: Hydrology.-The specific coverage phase for variable hydrologic facts consists primarily of collecting data for detailed project design. These collections of specific basic data, although often of great importance, are of necessity of short duration. It is often desirable or necessary to continue collection of certain items of these data after the immediate needs have been met in order to serve as useful units in the national data network as well as for project operations. Such special data generally are made fully useful only through the availability of the general coverage data and by means of appropriate correlations. Sedimentation.-Sediment sampling stations referred to under general coverage should be continued. Plans for establishing ranges in reservoir areas, upstream from the reservoir and downstream from the dam, should be made in order to obtain detailed information on rates of reservoir TABLE I.-Basic socio-economic data requirements by types, functions, and stages of development P-Planning (preliminary examinations, surveys, and definite project reports).
