Estimation of the annual rainfall erosivity index based on hourly rainfall data in a tropical region

The annual mean rainfall erosivity (R) indicates the potential soil loss caused by precipitation and runoff is used to predict from agricultural hillslopes. R calculated stations with continuously recording databases. However, many short-term real-time databases that also relate intensity are not readily available around Taiwan, hourly data being predominantly available. 10-min accumulation converted 30-min (R10_30) can be estimated using convert (R10_60) kinetic energy (E60j). maximum 60-min (I60j) has been established in throughout southern Taiwan. set consists of 15 221 storm events 2002 2017 monitored 51 located tropical regions According results this study, average conversion factors (1.04), (1.47), (1.30) could based on data.
