| description | The scarcity of information on the processes of rainfall-flow limits understanding of the hydrology of
dry regions of the world. In order to minimise the problem, this study was developed to investigate the influence
of the characteristics of rainfall events and plant cover on the effective precipitation (Pe) in a seasonally dry
tropical forest (SDTF) in the Northeast of Brazil. The study was carried out in two paired watersheds, one with
SDTF under regeneration for 35 years (CR35) and the other under thinned SDTF for 5 years (TC). A historical
series of five years (2009-2013) was analysed, with a total of 203 rainfall events, where only those rainfall events
that generated a Pe > 1.0 mm were considered. CR35 had a greater number of Pe events (47) than TC (35).
Rainfall depth and intensity were the factors that best explained the effective precipitation under both types of
vegetation cover. The influence of herbaceous vegetation on the reduction of surface runoff was demonstrated
by the smaller runoff depth and the greater potential for soil water storage in the watershed under thinned
Caatinga. This fact leads to the conclusion that the technique of thinning is suitable management for Caatinga
vegetation, and is capable of promoting the retention of soil water. |
