“…Rubber cuffs were glued on the trunks and directed the stemflow of each tree into 150 l vessels after passage through a modified tipping bucket rain gauge, enabling quantitative and temporal records of stemflow. For each sampling event the amount of stemflow was regressed against the DBH of the stemflow trees according to Hanchi and Rapp (1997): SF = aDBH n , where SF is the amount of stemflow in liter and a and n are specific constants for each sampling event. This function was applied for calculating the amount of stemflow for each beech tree in the pure and mixed stand and cumulative amounts of SF were related to ground area for expressing stemflow in liter per square meter (mm).…”

Studies on the combined effects of beechspruce mixtures are very rare. Hence, forest nutrition (soil, foliage) and nutrient fluxes via litterfall, throughfall (+ stemflow) and soil solution were measured in adjacent stands of pure spruce, mixed spruce-beech and pure beech on a nutrient rich site at Kreisbach, as well as in adjacent spruce and mixed stands on a nutrient poor site at Frauschereck to evaluate the impact of tree species composition (spruce versus beech) on these parameters. The highest recorded throughfall (+ stemflow) fluxes were 22.4 kg N ha −1 and 9.6 kg S ha −1 yr −1 and increased from beech over the mixed to the spruce stand at Kreisbach, but were similar for both stands at Frauschereck. At Frauschereck, atmospheric inputs were more or less reflected in element outputs, slightly modified by tree species composition. At Kreisbach, there was hardly any linkage between nutrient inputs and outputs. Our overall conclusion is that tree species composition affects forest nutrition, atmospheric input and consequently soil solution chemistry and inputoutput budgets of nutrients. However, these effects are site specific and dependent on the studied chemical element and process.

“…The collected stemflow was diverted to a HOBO tipping-bucket rain gauge using a 30 rubber hose with 2.5 cm in diameter. Following Hanchi and Rapp (1997), the tree-level S f was upscaled to the stand-level S f for both forest stands using Equation (3.1):…”

Vegetation Effects on Soil Moisture and Groundwater Recharge in Subtropical Coastal Sand Dunes

Vegetation can potentially have a strong influence on the water budget and hydrological processes in vegetated ecosystems due to canopy rainfall interception and the partitioning of rainfall into throughfall and stemflow, as well as root water uptake from the vadose zone or groundwater table. This study aims to explore the potential effects of vegetation on soil moisture dynamics and groundwater recharge in a subtropical coastal area of eastern Australia. This area is characterized by highly permeable sands, intense summer rainfall events and three typical vegetation covers (exotic pine plantation, native woodland and grassland).First of all, the spatial variability of both throughfall and stemflow at the soil surface was investigated in a 12-year-old managed pine plantation over one year on Bribie Island using tipping-bucket rain gauges. Rainfall loss by canopy interception and subsequent evaporation from this pine plantation and a native banksia woodland were also quantified and compared using field measurements and two analytical models of rainfall interception.In addition, the potential hydrological impacts of changes in vegetation cover in this shallow sandy groundwater system (depth to water table < 2 m) was evaluated by estimating groundwater recharge and discharge by evapotranspiration (ET g ) under the three contrasting vegetation covers over a 2-year period using the water table fluctuation method and the White method, respectively.To further monitor the actual water percolation processes in deep sand dune profiles (depth to water table > 10 m), spatial patterns and seasonal dynamics of root-zone soil moisture were quantified under three contrasting vegetation covers on North StradbrokeIsland by combining two geophysical techniques: surface electric resistivity tomography (surface ERT) and spatial time domain reflectometry (spatial TDR). Based on the field investigations of rainfall and root distributions at the under-canopy and inter-canopy zones, spatial distributions of vadose zone soil moisture and deep drainage in this subtropical coastal forest overlying deep sand dunes were finally simulated using HYDRUS models.On the Bribie Island sites, the highest throughfall was found on the east side of the tree trunks (~85% of gross rainfall) and the lowest in the midway between tree rows (~68% of gross rainfall) in the pine plantation. These spatial patterns persist for around 84% of recorded rainfall events. This is explained by canopy interception of the inclined rainfall resulting from the prevailing easterly wind direction throughout the experiment. Annual ii rainfall interception loss in the banksia woodland was lower (~16% of gross rainfall) than that in the pine plantation (~23% of gross rainfall) due to the lower canopy storage capacity and higher aerodynamic resistance of the banksia woodland. The RGAM and WiMo models predicted the interception losses from these forest stands reasonably well.The average annual gross recharge was largest at the sparse grassland site, followed by the exotic...
