annotated photos - Partitioning of rainfall by a canopy and the canopy features that provide visible indicators of pour point presence. (a) Rainfall intercepted by canopies is partitioned into interception loss (evaporation), throughfall, stemflow and pour points fluxes. Pour points are generated at visually identifiable features of the canopy including (b) the confluence of smaller branches or (c) a change in branch angle. The location where we expected the pour point to form is highlighted with yellow circles in (b) and (c).

annotated photos - Rainfall simulation experiments. (a) Br1 with the rainfall simulator operational hanging from the load cell using a fishing line. Br1 did not need a gauge to measure the stemflow as all the water was being drained at the bottom of the U-bend of the branch. (b) The plan view of the rainfall simulator with the throughfall arrangement. (c) Gingin branch was monitored in the field and then was brought to the simulator, as shown in the image, with the end of the branch going into a tipping bucket rain gauge for stemflow measurement. Three throughfall buckets separated from the rest of the gauges are marked as the control buckets in (b) and (c). They are not influenced by the branch and allow comparisons between trials.
