WORTH OF HYDROLOGIC DATA

Optimal design of data networks requires a measure of the worth of data. Worth is use specific and difficult to measure. Surrogates to worth, usually some measure of accuracy, have been developed. These surrogates and attempts to translate them to economic measures are discussed. Advances toward realism make solutions more difficult. Simplicity of solution and ease of understanding are required if methods developed are to have any impact on decision makers. Copyright 1979 by the American Geophysical Union.
