Última SEASONAL DYNAMICS OF AGRICULTURAL SOIL COVER IN RUNOFF GENERATION 70 Aguiar,Wagner de; Sampaio,Silvio C.; Paisani,Julio C.; Remor,Marcelo B.; Reis,Ralpho R. dos. ABSTRACT Seasonal changes in agricultural soil use due to agroclimatic conditions affect the water cycle in watersheds. This study aimed to understand the temporal variation of runoff inherent to the seasonal occupation dynamics of the agricultural soil in the basin that drains the upper valley of the Marrecas River, upstream of the urban perimeter of Francisco Beltrão, PR. The effects of runoff were verified through flow peaks simulated by the HEC-HMS model in twelve monthly soil use scenarios, under seven precipitation return periods. The results indicated a strong relationship between bare soil and flow peaks, temporally delimiting April and March as the largest runoff generators and January and August as the smallest ones. The ratio quantified by rates... Tipo: Info:eu-repo/semantics/article Palavras-chave: Flood; Flow peak; Hydrological simulation; Agricultural soil use.
