“…This prolonged dry period reduces soil moisture to the point where water repellency is triggered (Dekker et al, 2001;2004;Verheijen and Cammeraat, 2007;Martínez-Murillo and Ruiz-Sinoga, 2010;Prats et al, 2013;Martínez-Murillo et al, 2013). On the other hand, summer drought favours the presence of deciduous and semi-deciduous plant species (Orshan, 1964(Orshan, , 1972, which shed their oil-or wax-rich leaves in summer (Moral García et al, 2005), providing hydrophobic compounds to the soil surface. Moreover, in Mediterranean areas there is also a high recurrence of forest fires that are frequently related to SWR appearance (Úbeda and Mataix-Solera, 2008).…”

Seasonal changes in the soil hydrological and erosive response depending on aspect, vegetation type and soil water repellency in different Mediterranean microenvironments

et al. 2013

Abstract. Mediterranean areas are characterized by a strong spatial variability that makes the soil hydrological response highly complex. Moreover, Mediterranean climate has marked seasons that provoke dramatic changes on soil properties determining the runoff rates, such as soil water content or soil water repellency (SWR). Thus, soil hydrological and erosive response in Mediterranean areas can be highly time-as well as space-dependant. This study shows SWR, aspect and vegetation as factors of the soil hydrological and erosive response. Erosion plots were set up in the north-and the south-facing hillslope and rainfall, runoff, sediments and SWR were monitored. Soil water repellency showed a seasonal behaviour and it was presented in three out of four microenvironments after the summer, disappearing in the wet season. In general, runoff rate was higher in shrubs patches (0.47 ± 0.67 mm) than in inter-shrub soils (1.54 ± 2.14 mm), but it changed seasonally in different ways, depending on the aspect considered, decreasing in the north-facing hillslope and increasing in the south-facing one. The main factor determining the hydrological and erosive response was the rainfall intensity, regardless of the rainfall depth of the event. This response was modulated mainly by SWR in the north-facing hillslope and the vegetation pattern in the south-facing one.

“…Non-wetting phenomena observed in soils originate from the effects of wildfire [1], precipitation of volatile and non-hydrocarbon components on soil particles [2,3], and organic substances produced from vegetation [4]. The hydrophobic nature of soils prevents water from permeating into the subsurface, resulting in substantial increases in hill slope runoff [5], soil erosion, and overflow unpredictability [6,7].…”

Experimental Investigation of Evaporation and Drainage in Wettable and Water-Repellent Sands

et al. 2015

This study presents experimental results on evaporation and drainage in both wettable and water-repellent sands whose surface wettability was artificially modified by silanization. The 2D optical and 3D X-ray computed tomographic imaging was performed during evaporation and the water retention during cyclic drainage and infiltration was measured to assess effects of wettability and initial wetting conditions. The evaporation gradually induces its front at the early stage advance regardless of the wettability and sand types, while its rate becomes higher in water-repellent Ottawa sand than the wettable one. Jumunjin sand which has a smaller particle size and irregular particle shape than Ottawa sand exhibits a similar evaporation rate independent of wettability. Water-repellent sand can facilitate the evaporation when both wettable and water-repellent sands are naturally in contact with each other. The 3D X-ray imaging reveals that the hydraulically connected water films in wettable sands facilitate the propagation of the evaporation front into the soil such that the drying front deeply advances into the soil. For cyclic drainage-infiltration testing, the evolution of water retention is similar in both wettable and water-repellent sands when both are initially wet. However, when conditions are initially dry, water-repellent sands exhibit low residual saturation values. The experimental observations made from this study propose that the surface wettability may not be a sole factor while the degree of OPEN ACCESSSustainability 2015, 7 5649 water-repellency, type of sands, and initial wetting condition are predominant when assessing evaporation and drainage behaviors.
