Abstract
Rain gauge networks have limited spatial resolutions. Conventional methods such as Thiessen Polygon method, Isohyetal method and Reciprocal-distance-squared method are easy to use but unable to provide information on uncertainties. Geostatistical methods such as Kriging are able to provide point rainfall estimation and catchment average rainfall, as well as uncertainty information on the estimated values.
Keywords: point rainfall, catchment average, geostatistics, semivariogram, Kriging
