Paper F.1

Two Recent Methods For Computing Average Precipitation

P.W. France
University of Wales, UK

Abstract

Three techniques, a traditional approach (isohyetal map) and two recent developments, (a distance weighted method and a finite element approach) have been used to estimate the average area precipitation on several different catchments. Since it is generally recognised that the isohyetal map technique produces the most accurate results of the traditional methods, these have been used as a basis for comparison with the values obtained from the two new techniques. Each method has its advantages and disadvantages, but the results indicate that in terms of accuracy there is little difference between the techniques.
