Studies on Rainfall-Runoff Modeling, 1. Estimation of Mean Areal Rainfall

The current methods of estimating mean areal rainfall are presented. By applying them to five different areas of the world an objective comparative assessment is made of their performance. Advantages and disadvantages of each method are enumerated. It is shown that for many hydrologic problems simpler methods are as good as more sophisticated ones – an observation contrary to what is generally believed.
