Research about building correlative relation between the effective rainfall and the actual rainfall in Quang Nam province

Abstract

   By method of analyzing the correlative relationship between the effective rainfall and the actual rainfall based on imitation of chart line with field-surface layer in Quang Nam province. The result shows:

1. For the correlative relationship between the effective rainfall and the actual rainfall following

the heavy rain is not clos. Therefore, it's hard to build strong ralationship between the effective

rainfall and the actual rainfall according to the heavy rainfall.

2. For the correlative relationship between the effective rainfall and the actual rainfall following

the month-rain and the seasonal rain is very close. So can build the correlative relationship between them to serve for the determination of the effective rainfall in the irrigation regime calculation to ensure the necessary trust.
