Forest tree canopies have a critical influence on water cycles through the interception of precipitation. Nevertheless, radial patterns canopy may vary interspecifically. We analyzed using catchments along transects underneath four common forest species (Acer macrophyllum, Alnus rubra, Pseudotsuga menziesii, and Thuja plicata) in Pacific Northwest over two years. Near center leaf-off season, wa...

Climate has always varied. In Australia, the impact of the El Niño – Southern Oscillation on variations in rainfall over centuries has been documented (e.g. Nicholls 1988, 1989). Other natural, internal processes also affect climate on different time-scales. As well, volcanic activity is known to cause cooling of the surface temperature, and variations in solar activity and orbital changes that...

Hydrological behavior in reforested watersheds is different from that under other forms of cover. The variation may be related to aspects intrinsic species, planting density, physiological maturity, management system and climatic conditions. Periodically, anomalies such as the case La Ninã are observed, these responsible for alteration rainfall regime consequently generate water deficits southe...

Although it is well known that forest canopies reduce the amount and intensity of precipitation at the ground surface, little is known about how canopy interception modifies extreme events. This research investigated the effects of forest cover on intensity-duration-frequency relationships using a stochastic model to extrapolate measured rainfall and throughfall to throughfall expected during e...

We determined 116 globally important woody tree species, classified them based on the differences between plant life-forms, leaf textures and trichomes leaves measured indices of some morphological traits in Guizhou karstic regions China. The water adsorbed upper surfaces branches lower (WW u WW ul ) these species was measured. ratios weight to (RWW were calculated. adsorption trait follow appr...
