Kosten-Baten Beschouwingen ten Behoeve van het Ontwerpen van Hydrologische Meetnetten (Cost-Benefit Considerations for the Design of Hydrometric Networks)

摘要

The aim of a network of gauging stations is to produce information about a hydrological variable. It might be possible to arrive at a maximum information content by a very dense, thus expensive network. On the other hand a less dense network will lead to a certain loss of information, but against lower cost. The best solution is found if the sum of information loss and network costs shows a minimum. The density of such an optimum network depends on four factors: (1) the socio-economic value of the data; (2) the costs of a unit network; (3) the correlation structure of the phenomenon under consideration; (4) the variability in time of the phenomenon. The factors 1 and 4 tend to increase the density, and the factors 2 and 3 tend to decrease it. A water level gauging network is discussed as an example.
