The study of temporal distribution of rainfall is carried out to characterize the most frequent rainfall patterns. Knowledge of the physical characteristics of rainfall in relation to rainfall patterns allows mathematical modeling to be performed in regard to hydrologic events more nearly approaching real conditions. The objective of this study was to characterize the erosive rains from the municipality of Urussanga, SC, Brazil in regard to hydrological patterns of temporal distribution. Rainfall records from the meteorological station of Urussanga (28.31° […]

Specific rainfall characteristics vary among regions and their erosion potential must be known for the planning of agricultural and civil engineering activities. For Rio Grande (RS, Brazil), the erosivity and relationships with the precipitation and rainfall coefficient, rainfall hydrologic patterns and return period were determined based on rainfall data of 23 years. For each erosive rainfall the segments of the rainfall chart with the same intensity were separated together and the data registered in worksheets. The mean monthly and annual […]
