Estimating Rainfall in Rodrigues by Geostatistics: (b) Application

Abstract

The previous paper described the kriging method and its possible applications. This paper checks whether kriging may be used to estimate rainfall. Four test stations were selected in Rodrigues. Rainfall data from surrounding stations were used to estimate rainfall at these stations, after first establishing a suitable semivariogram. The rainfall estimates were then compared to the actual recorded rainfall data at the test stations. A high correlation was obtained in all the cases.

Keywords: rainfall, semivariogram, kriging, estimate.
