Rainfall network design through comparative kriging methods

摘要

The methods of simple and disjunctive kriging are applied and compared in the estimation of optimum locations of recording raingauges as part of a network for the determination of storm characteristics to be used in forecasting and design. Some advantages are shown but problems arise when there are large differences in storm structures and movements. Another source of uncertainty is in the modelling of the semi-variogram. Application is made to the management of an area of the Severn-Trent water basin, UK, with 13 autographic raingauges.
