“…These values were lower than those reported previously on the same basis: water storage after drainage of Pinus radiata slash was 0.7 mm (Kelliher et al, 1992); Putuhena and Cordery (1996) found that C min was 0.96 and 1.12 mm for coniferous and eucalyptus litter types; Tobon-Marin et al (2000) for Amazonian rainforest litter reported 1.5 mm storage after drainage; the C min reported by Sato et al (2004) for coniferous and broadleaved litter types were in the range of 0.27-3.05 mm and; measured C min of bracken litter was 1.67 mm (Pitman, 1989). The discrepancy with the results of the present work was explained by the different materials analyzed but also could be attributed to the different methodological approaches to simulate rainfall.…”

Abstract. Many hydrological studies of forested ecosystems focus on the study of the forest canopy and have partitioned gross precipitation into throughfall and stemflow. However, the presence of forest litter can alter the quantities of water available for soil infiltration and runoff. Little information exists regarding the value of storage and drainage parameters for litter layers. Vegetation parameters of this kind are required in physically-based and lumped conceptual models to quatify the availabilty and distribution of water. Using a rainfall simulator and laboratory conditions two main objectives were investigated using layers of recently seneced poplar leaves, fresh grass or woodchips: 1) Effect of rain intensity on storage. With this respect we found that: maximum storage (C max ), defined as the detention of water immediately before rainfall cessation, increased with rainfall intensity. The magnitude of the increment was up to 0.5 mm kg −1 m −2 between the lowest (9.8 mm h −1 ) and highest (70.9 mm h −1 ) rainfall intensities for poplar leaves. Minimum storage (C min ), defined as the detention of water after drainage ceased, was not influenced by rainfall intensity. Repeated wetting-draining cycles or layer thickness have no effect on C max or C min .2) The evaluation of drainage coefficient for the Rutter model. This model was found accurate to predict storage and drainage in the case of poplar leaves, was less accurate for fresh grass and resulted in overestimations for woodchips.Additionally, the effect of an underlaying soil matrix on lateral movement of water and storage of poplar leaves was studied. Results indicated that the soil matrix have no effect on C max or C min of the litter layer. Lateral movement of water in the poplar layer was observed at intermediate rainfall intensities (30.2 and 40.4 mm h −1 ), but not a the lowest or highest rates.

“…A large number of interception studies have been studied in tropical rainforest (Hutjes et al 1990;Jetten 1996), seasonal temperate rainforest (Link et al 2004), temperate broadleaf (Hörmann et al 1996) and temperate conifer forests (Rutter et al 1972;Valente et al 1997). The majority of interception studies in temperate conifer canopies have been research in relatively young plantation forests in Europe (Ford and Deans, 1978;Gash and Stewart 1977;Gash et al 1980;Johnson 1990;Kelliher et al 1992;Rutter et al 1972;Viville et al 1993). Most interception studies in temperate conifer canopies have been studies in Europe.…”

Aim of study: In order to test the adaptability of revised Gash analytical model to canopy interception of Pinus tabulaeformis plantation, determine local parameters in the model, and analyze the sensitivity of the parameters to the simulated interception.Area of study: The throughfall experiment has been completed in Hebei province of China during 2010. Material and methods:During the experiment process, rainfall, throughfall and stemflow were measured and canopy interception was simulated with the revised Gash analytical model. Main results:The results show that the rate of measured throughfall, stem flow and canopy interception occupied to rainfall were 67.08%, 3.10% and 29.82%. Canopy storage capacity, stem storage capacity and Stemflow partitioning coefficient was 2.68 mm, 1.22mm and 0.03. Evaporation rate varied from 0.01 to 0.37 mm ⋅ h -1 and the ratio of evaporation and rainfall (E/R) ranged from 0.01 to 0.19 in rainfall periods.Research highlights: The revised gash model was able to accurately simulate the weekly canopy interception of Pinus tabulaeformis forest.

Net canopy interception (I net ) during rainfall in an old-growth Douglas-fir-western hemlock ecosystem was 22.8 and 25.0% of the gross rainfall (P G ) for 1999 and 2000, respectively. The average direct throughfall proportion (p) and canopy storage capacity (S) derived from high-temporal resolution throughfall measurements were 0.36 and 3.3 mm, respectively. Derived values of S were very sensitive to the estimated evaporation during canopy wetting (I w ). Evaporation during wetting was typically small due to low vapor pressure deficits that usually occur at the start of an event, therefore I w is best estimated using the Penman method during canopy wetting, rather than assuming a constant evaporation rate over an entire event. S varied seasonally, from an average of 3.0 mm in the spring and fall, to 4.1 mm in the summer, coincident with canopy phenology changes. Interception losses during large storms that saturated the canopy accounted for 81% of I net . Canopy drying after events comprised 47% of I net , evaporation during rainfall comprised 33%, and evaporation during wetting accounted for 1%. Interception associated with small storms insufficient to saturate the canopy accounted for 19% of I net . The Gash analytical model accurately estimated both I net and the individual components of I net in this system when applied on an event basis, and when the Penman method was used to compute evaporation during rainfall. The Gash model performed poorly when applied on a daily basis, due to a rainfall regime characterized by long-duration events, which violated the assumption of one rain event per day.
