“…J. Zhang, van Meerveld, et al, ) were used in regression equations linking the Basper gauge to the respective gauges at Manobo ( R 2 = 0.85–0.88) to estimate P at Manobo. No corrections were made for wind‐related underestimation of P because wind speeds (as measured at the Basper weather station) were generally low and the application of correction methods (e.g., Førland et al, ) for the extreme wind speeds encountered during the Haiyan event (Rabonza et al, ) would have led to unverifiable and uncertain corrections. Instead, a recording cylindrical fog gauge placed at the Basper station that has a 100% catch efficiency for near‐horizontal wind‐driven rain (Frumau et al, ) was used to estimate extra inputs of near‐horizontal wind‐driven rainfall during the Haiyan event.…”

“…and 11 km from Manobo). Average monthly wind speeds at Tacloban airport vary between 1.5 and 2.4 m s −1 but can be very high during typhoon events (Rabonza et al, ). Average daily reference evaporation ET 0 (Allen, Pereira, Raes, & Smith, ) calculated using basic climatic data for Tacloban Airport ranges between 3.0 (December) and 4.8 mm day −1 (April), with an annual total of 1,385 mm.…”

Average daily reference evaporation ET 0 (Allen, Pereira, Raes, & Smith, 1998) is 2,660 mm (range 1,435-4,790), distributed over on average 195 rain days (i.e., with ≥0.5 mm of rain each).…”

“…Being located in one of the world's premier cyclone-generating areas (García-Herrera, Ribera, Hernández, & Gimeno, 2007), the Philippines typically receive nearly a third of their annual precipitation during the passage of tropical cyclones and depressions (Cinco et al, 2016). During the study year, Leyte Island was hit by Typhoon Haiyan, one of the strongest and largest events on record (Nguyen et al, 2014;Rabonza et al, 2015). This provided a unique opportunity to study the effect of this particularly extreme event and the associated disturbance of the vegetation on run-off production.…”

Water budget and run‐off response of a tropical multispecies “reforest” and effects of typhoon disturbance

et al. 2018

To examine claims that reforesting degraded Imperata grassland in Leyte (Philippines) made streamflow perennial again, we studied the hydrological behaviour of a 23‐year‐old mixed‐species “reforest” between June 2013 and May 2014. Typhoon Haiyan, one of the strongest events ever, caused major damage to the site in November 2013. Average daily apparent water use (ET) was 5.0 mm day−1 pretyphoon and 3.2 mm day−1 after disturbance. Corresponding ratios of period total quickflow Qq to precipitation were 16% and 44%. Quickflow volume and peak discharge increased rapidly once a threshold value of ~250 mm for soil water storage in the top 60 cm was exceeded. Before disturbance, quickflow consisted predominantly of lateral subsurface flow due to high soil hydraulic conductivities down to 60 cm. After disturbance, shallow groundwater rose regularly to within 10 cm of the surface on foot slopes, and saturation overland flow was observed during several large storms. Comparing estimated annual ET and Qq for undisturbed conditions for the reforest and a nearby degraded Imperata grassland microcatchment suggested that the extra infiltration following reforestation (~240 mm year−1) exceeded the extra ET by the reforest (100–185 mm year−1), implying a net positive trade‐off (55–140 mm year−1) and tentatively confirming local claims of improved dry‐season flow.

The construction of earthen embankment terraces in the Douro Region raises a set of problems related to hydrological processes. The main objective of this study is the evaluation of the spatial variation of electrical resistivity in agriculture terraces at Douro valley (Portugal). To achieve this objective, two variables are analysed, the soil electrical resistivity and the flow direction algorithm. In a field survey we recorded 13 electrical resistivity profiles. The contributing area was calculated with the algorithms D∞ (Deterministic Infinity Flow) and MFD (Multiple Flow Direction) and the results are the base of the internal runoff modelling, both supported by the digital elevation model with a spatial resolution of 1m2. A correlation between the spatial variation of the soil electrical resistivity represented by the standard deviation of the electrical resistivity for each profile and the average value of the contributing area coincident with each profile was established. The electrical resistivity standard deviation seems to be moderately well correlated according to the D∞ algorithm at about 1m of depth, and it has a good correlation at 1,5m to 2m of depth with the MFD algorithm. Taken together, the results show a significant positive statistical correlation between the electrical resistivity standard deviation and the contributing areas (MFD and D∞) depending on the soil depth.
