Package: Rfactor 0.2.0.9000

Rfactor: Rainfall Erosivity Calculations from Precipitation Records

Calculates rainfall erosivity from timestamped precipitation records. The package identifies rainfall events, calculates continuous rolling rainfall intensities, rainfall kinetic energy, and event EI30 erosivity, aggregates contributing event erosivity to monthly and yearly totals, and calculates multi-year mean monthly and annual rainfall erosivity. Storm separation, event omission criteria, intensity durations, and rainfall kinetic-energy equations are configurable. Rainfall kinetic energy can be calculated using the formulations of Brown and Foster (1987) <doi:10.13031/2013.31957>, McGregor et al. (1995) <doi:10.13031/2013.27921>, and Laws and Parsons (1943) <doi:10.1029/TR024i002p00452>.
