Abstract

DAVID, Teresa Soares. Intercepção da Precipitação em Árvores Isoladas de Quercus rotundifolia Lam. Silva Lus. [online]. 2002, vol.10, n.1, pp.1-15. ISSN 0870-6352.

Rainfall interception was monitored for two years in an isolated Quercus rotundifolia Lam. tree, in a low-density oak woodland (montado) near Évora. Interception loss was 21.7% of gross rainfall and 28% of tree evapotranspiration. Rainfall redistribution under the crown resulted in rainfall increases in upwind directions (South and West) and depletions downwind (North and East). Rainfall concentration in some areas beneath the crown is certainly of importance in explaining the spatial heterogeneity of the understory.

Keywords : montado; interception loss; rainfall redistribution; evapotranspiration.
