| الوصف: | Rainfall takes many flowpaths to reach a stream, and the success of riparian buffers in water quality management is significantly influenced by riparian hydrology. This paper presents results from hydrometric monitoring of riparian buffer hydrology in a pasture catchment. Runoff processes and riparian flowpaths were investigated on two planar hillslopes with regenerating grass and E. globulus buffers. Surface runoff and subsurface flows (A- and B-horizons) were measured for 3 years using surface runoff collectors, subsurface troughs and piezometers. Water volumes moving through the riparian buffers via the measured flowpaths were ranked B-horizon ≫ surface runoff ≈ A-horizon. Runoff volumes through the B-horizon troughs were an order of magnitude greater than those recorded for the most productive surface runoff plots or the A-horizon troughs. Subsurface runoff and saturation-excess overland flow (SOF) were limited to the winter months, whereas infiltration-excess overland flow (IEOF) can occur all year round during intense storms. Surface runoff was recorded on 33 occasions, mostly during winter (late May–early October), and total annual surface runoff volumes collected by the 20 unconfined (2 m wide) runoff plots varied between > 80 and < 20 m3. Subsurface flow only occurred in winter, and the 6 m wide B-horizon subsurface troughs flowed above 1 l s−1 continuously, whereas the A-horizon troughs flowed infrequently ( |
