The Rainfall Example Data Set-Runoff Erosivity Factor

Description

Data set for determination of rainfall runoff erosivity factor

Details

Data should be organized into notebooks or spreadsheets, where the first column being the date (dd/mm/yyyy), the second one, the hour column (hh:mm) and the third column the precipitation in mm. The dot (.) must be used as decimal separator.

The results of package is: Monthy value (Final rainfall sum, Total erosivity [EI30], Number erosive, Number non erosive, Total erosive sum, Total non erosive sum).Annual value (Final rainfall sum, Total erosivity [EI30], Number erosive, Number non erosive, Total erosive sum, Total non erosive sum). R factor (average total erosivity)
