A Systematic approach to the
redesign of the raingauge network of Zambia, by P. Hutchinson, Zambia
Journal of Science & Technology, Vol.1, no.2, April 1976, Pg. 69-75.
Zambia's national raingauge network of about 500 gauges is inadequate and I its
improvement is an integral part of development. The paper recommends a design of
the network based on systermatic spatial variability of rainfall. The principal
component analysis is used in the actual redesign of the network. The analysis
shows that most of the Western and Northwesten Provinces require to be lightly
gauged but parts of Luapula, Northern, Eastern and Central Provinces require a
dense network. These findings agree very well with the results obtained by other
methods. Based on the findings, recommendations of network densities are given.
