“…The average annual interceptions for the 1986-2012 period were 35% and 25% under spruce and beech stands, respectively (Table 1, Suplementary materials). These data were comparable with those published by Viville et al (1993) and Dambrine et al (1998b) for the same spruce plot during a summer period (34-35%) and for the same beech plot (Biron, 1994;25%) or with other similar spruce and beech plantations (Delfs, 1965;Nihlgård, 1970;Bultot et al, 1972;Johnson, 1990;Staelens et al, 2008;Berger et al, 2008).…”

Twenty-five year record of chemicals in open field precipitation and throughfall from a medium-altitude forest catchment (Strengbach -NE France): an obvious response to atmospheric pollution trends. (2019) Atmospheric Environment, 202. (A. Probst).T 2 enhanced the capture of particles and water, accentuating the acidity of the deposition and leading to the intensification of acidification processes, nutrient leaching in soils and forest decline. In contrast, beech leaves were able to neutralize a portion of the atmospheric protons, which minimized and reduced the negative effects of acid rain. In addition, the throughfalls represented an important part of the biological cycle of trees for some elements such as K or N, as indicated by the contrasting patterns at year and long-term scales regarding the vegetation type. However, our study indicated that the influence of tree species might change over time with changes in atmospheric pollution, in precipitation regime, or in stand structure.This study outlined the importance of the long-term record of open field precipitation and throughfalls under various tree types to better evaluate the real inputs of elements to forest ecosystems and among them, essential mineral nutrients.

“…Trimble and Weitzman (1954) attribute greater summer throughfall during high intensity rain to previously intercepted water being physically beaten from downward sloping leaves'' (Helvey and Patric 1965). Bultot et al (1972) and Wells and Blake (1972) have shown that interception and rainfall intensity are inversely related to each other. For a Pinus radiata forest in Whakarewarewa in New Zealand, Wells and Blake (1972) have observed an increase in interception during the early part of the storm, and a subsequent decrease in interception with increasing intensity.…”

At a local scale, the interception capacity of the canopy depends on a variety of climatic and canopy factors. Of particular importance is the intensity of rainfall-interception capacity varies inversely with rainfall intensity. At a field or regional scale, like the scale of global climate models, the spatially averaged interception also depends significantly on the spatial variability of rainfall intensity and total precipitation depth. A new parameterization of canopy interception is developed. In the new parameterization, the spatial average of actual interception is obtained as a function of rainfall intensity and total precipitation depth, and of an interception capacity, which depends on the characteristics of the leaf surface and of the vegetation cover. In a statistical-dynamical framework, the new parameterization also accounts for the subgrid-scale spatial variability of rainfall intensity and total precipitation depth. The implications of accounting for the dependence of interception capacity on rainfall characteristics are examined by assessing the consequent responses of the energy and the water fluxes at the land surface. This is accomplished by incorporating the new parameterization into a soil-plant-atmosphere column model that is fundamentally based on the physical parameterizations of NCAR's Community Climate Model.

“…It is generally accepted that trees intercept more water under scattered showers than under storm events. Bultot et al (1972) reported a 30% decrease in IW in the Belgian Ardennes region when rainfall intensity increased from0.1mmin10minto1mmin10min.DataonPinus radiata also showed a significant decrease in IW with amount of rainfall during a shower, from more than 80% for a few millimetres of rain to less than 20% for 60 mm or more (Humbert and Najjar, 1992). From a duration point of view, Olszewsky (1976) showed that the percentage of water that never reaches the soil in a broadleaved forest in Poland decreased from about 65% to less than 20% when duration of the rain event increased from a few minutes to 16 h.…”

Abstract• In forests, rainfall is partitioned into intercepted water (IW), throughfall (TF) and stemflow (SF). We reviewed the majority of published works comparing water flows among tree species in temperate and boreal forests to test the effect of several tree traits on water flows.• We hypothesized that water flows differed between evergreen and deciduous species, and according to successional status and bark roughness. We also investigated that water flows would be explained by stand variables such as basal area.• Linear mixed models fitted on reviewed data showed that evergreens had a lower TF than deciduous trees (decrease of 13.9% of total precipitation year-round and 8.4% over the growing period). Similar results were found for conifers compared to broadleaves. TF also declined with the successional status from pioneer to late-successional tree species. SF decreased with bark roughness from smoother to rougher bark. Evergreens had water flows that were dependent on age of the stand, especially for TF which increased by 15.6% of total precipitation from young to adult forests.• The large scale of TF differences between tree genera together with specific transpiration amounts and rooting features highlighted in other studies should result in significant differences in soil water content among tree species. This may have consequences on stand fitness and growth, and understory vegetation. Mots-clés :eau / traits des arbres / écoulement / égouttement / interception Résumé -Effet de quelques traits des arbres sur la répartition des eaux de pluie en forêts tempérées et boréales -synthèse bibliographique.• En forêt, l'eau de pluie se fractionne en eau interceptée (IW), égouttements (TF) et écoulements le long des troncs (SF). Nous analysons les publications comparant les flux d'eau selon les essences d'arbres, pour les forêts tempérées et boréales, et nous testons l'effet de quelques traits des arbres sur ces flux d'eau.• Nous faisons l'hypothèse que les flux d'eau diffèrent entre les essences à feuilles persistantes et les essences à feuilles caduques, et diffèrent selon le statut successionnel de l'essence et la rugosité de son écorce. Nous testons aussi l'effet de variables du peuplement telles que sa surface terrière.• L'analyse des données (par modèle linéaire à effets mixtes) montre que les essences à feuilles persistantes ont des égouttements (TF) plus faibles que les essences à feuilles caduques (diminution de 13,9 % des précipitations totales en moyenne sur toute l'année et de 8,4 % pour la période estivale). Les résultats sont similaires en comparant les conifères au feuillus. Les égouttements diminuent aussi avec le stade successionnel de l'essence, des pionnières vers les dryades. Les écoulements (SF) diminuent nettement avec la rugosité de l'écorce, des plus lisses vers les plus rugueuses. Les essences à feuilles persistantes ont des flux d'eau qui dépendent de l'âge du peuplement : les égouttements augmentent de 15,6 % des précipitations totales en passant des jeunes forêts aux forêts adultes.• L'...
