“…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.…”

“…Similarly, storage capacity of litter layers can be defined as the depth of water stored or detained on the plant surface in still air (Horton, 1919). Two parameters of storage are important: transitory or maximum storage (C max ), which is water that would later drip and; residual or minimum storage (C min ), that depth of water removed only by evaporation ( Pitman, 1989;Putuhena and Cordery, 1996). Particularly, C min represents the threshold of T h depth that result in drainage from the litter layer.…”

“…Furthermore, live foliage elements can hold water by adsorption while absorption also occurs in the case of dead plant material or bark; these two processes modify the storage properties of materials (Pitman, 1989). Also, decomposition of plant material would increase the proportion of water absorbed.…”

“…However, the mass of litter on the ground varies in space and time; species composition, wind, water, fire, animals and decay are important factors. Recent research in this field sampled the upper layer of the forest floor and analyzed interception under natural rainfall (Gerrits et al, 2007) or simulated rainfall (Pitman, 1989;TobonMarin et al, 2000;Sato et al, 2004). These studies indicate that storage capacity of litter layers increased linearly to litter mass (Putuhena and Cordery, 1996;Sato et al, 2004).…”

“…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. Pitman (1989) used a fine spray at a rate of 150 mm h −1 and wetted the litter sample until constant weight was obtained; Sato et al (2004) used a pressurized raindrop simulator at rates of 5, 10 and 50 mm h −1 during three hours; Putuhena and Cordery (1996) used a rainfall simulator that produced drops starting from zero velocity and the falling drops then stroked a splash screen 2 m above the sample tray that produced drops 2-3 mm in diameter. Tobon-Marin et al (2000) manually sprinkled water until water excess was observed and the samples showed to be completely wet.…”

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.

Seasonal evolution of ecohydrological controls on land surface temperature over complex terrain

The spatiotemporal distribution of Land Surface Temperature (LST) is linked to the partitioning of the coupled surface water and energy budgets. In watersheds with a strong seasonality in precipitation and vegetation cover, the temporal evolution of LST patterns are a signature of the interactions between the land surface and atmosphere. Nevertheless, few studies have sought to understand the topographical and ecohydrological controls on LST in regions of complex terrain. Numerical watershed models, tested against spatially distributed field and remote sensing data, can aid in linking the seasonal evolution of LST to meteorology, terrain, soil, and vegetation. In this study, we use a distributed hydrologic model to explore LST patterns in a semiarid mountain basin during the transition from a dry spring to the wetter North American monsoon (NAM). By accounting for vegetation greening through remotely sensed parameters, the model reproduces LST and surface soil moisture observations derived from ground, aircraft, and satellite platforms with good accuracy at individual sites and as spatial basin patterns. Distributed simulations reveal how LST varies with elevation, slope, and aspect and the role played by the seasonal vegetation canopy in cooling the land surface and increasing the spatial variability in LST. As a result, LST is shown to track well with ecosystem-specific changes in vegetation cover, evapotranspiration, and soil moisture during the NAM. Furthermore, vegetation greening is shown to modulate the spatial heterogeneity of LST during the NAM that should be considered in subsequent atmospheric studies in regions of complex terrain.
