In the sixth issue of 1981, I briefly introduced the main contents of foreign soil loss equation and the meaning of each factor and its application. Let us now introduce the calculation method of R factor and C factor. First, the calculation of R factor R factor is an indicator of rainfall erosivity. It is a function of rainstorm kinetic energy and rain intensity, calculated as follows:
