  abstract = {{T}he measure of rainfall erosive potential is becoming object of many studies, since this parameter is indispensable in the studies of models for the prediction of soil losses through hydrical erosion. {T}his study was carried out at {EMGOPA}/{E}mbrapa-{CNPS} experimental station, to determine the rainfall erosivity for the {G}oiania region, {GO}, {B}razil, through rainfall graphical data. {T}he rainfall annual average erosivity for the region was 8353.0 {MJ} mm/ha/year and 129.8 {MJ}/ha/year, respectively for {EI}30 and {KE} > 25. {T}he correlation coefficients showed that the rainfall and rainfall coefficient allow to estimate the rainfall erosivity in the absence of more complete rainfall data. {T}he erosion critical period, due to the occurrence of erosive rainfalls is from {S}eptember to {F}ebruary, when 85.70% and 84.05% of the {KE} > 25 and {EI}30 annual total, respectively, occurr. {I}n this period, conservation practices are necessary in order to reduce the hydrical erosion, for the maintenance of soil sustainability.
