“…According to Neris et al (2013a), water retention at 33 kPa can show a considerable increase after the fire in accordance with the decrease of bulk density, but in contrast to the observed decrease in aggregate stability. Although an increase in water retention at 33 kPa of tension has been reported widely for different soil types, the reported figures for burned Andosols (up to 75% of water retention at 33 kPa after the fire) largely exceeded those reported for nonvolcanic soils , Stoof et al 2010. This can enhance infiltration and reduce both runoff and erosion.…”

“…This can enhance infiltration and reduce both runoff and erosion. According to Stoof et al (2010) and Neris et al (2014), this response can be attributed to the incorporation of partially combusted char, which generally shows a higher amount of large pores compared to the soil itself (Cerdà & Doerr 2008). However, the effect of fire on water retention at 1500 kPa is generally less pronounced than at lower tensions.…”

Andosols are the most characteristic soils of volcanic regions such as the forested, fire-prone, hillslopes of the mountainous Canary Islands (Spain). Due to their volcanic nature, these soils have traditionally been considered highly resistant to water erosion processes in undisturbed conditions, but are also highly susceptible to environmental disturbances. In addition, volcanic terrains often underlie heavily-populated, steep areas where torrential rains are frequent, increasing the threat to the population and infrastructures downslope. Numerous hydrological and erosional catastrophic events in disturbed Andosols in the Canary Islands and worldwide, leading to major losses to lives and properties, have been historically and recently reported. The impact of environmental alterations such as land use change on hydrological and erosional response of Andosols has been widely studied in the Canary Islands and worldwide. However, the effect on this soil type of wildfires, generally considered one of the main geomorphological agents, and historically connected to the forested fire-prone Andosols of the islands, has had scant attention to date. This review seeks to redress this knowledge gap by: (i) evaluating the factors affecting the susceptibility of Andosols to catastrophic hydrological and erosional events; (ii) summarizing the published studies on the impact of fire and the post-fire response of this soil type and the specific restoration measures developed to date; and (iii) identifying research gaps and suggesting new lines of investigation in order to reduce the hydrological and erosional risks in these particular terrains.

Abstract. Many forested watersheds with a substantial fraction of precipitation delivered as snow have the potential for landscape disturbance by wildfire. Little is known about the immediate effects of wildfire on snowmelt and near-surface hydrologic responses, including soil-water storage. Montane systems at the rain-snow transition have soil-water dynamics that are further complicated during the snowmelt period by strong aspect controls on snowmelt and soil thawing. Here we present data from field measurements of snow hydrology and subsurface hydrologic and temperature responses during the first winter and spring after the September 2010 Fourmile Canyon Fire in Colorado, USA. Our observations of soil-water content and soil temperature show sharp contrasts in hydrologic and thermal conditions between northand south-facing slopes. South-facing burned soils were ∼1-2 • C warmer on average than north-facing burned soils and ∼1.5 • C warmer than south-facing unburned soils, which affected soil thawing during the snowmelt period. Soil-water dynamics also differed by aspect: in response to soil thawing, soil-water content increased approximately one month earlier on south-facing burned slopes than on north-facing burned slopes. While aspect and wildfire affect soil-water dynamics during snowmelt, soil-water storage at the end of the snowmelt period reached the value at field capacity for each plot, suggesting that post-snowmelt unsaturated storage was not substantially influenced by aspect in wildfireaffected areas. Our data and analysis indicate that the amount of snowmelt-driven groundwater recharge may be larger in wildfire-impacted areas, especially on south-facing slopes, because of earlier soil thaw and longer durations of soil-water contents above field capacity in those areas.

“…Large fires have significant impact on environment including water pollution as a result of using extinguishing foams [1,2], soil contamination caused by both the extinguishing agents and fire water [3,4]. Another influence of fires is an air pollution as a result of emission combustion products to the atmosphere.…”

Abstract. The analysis of the large-scale commercial buildings fires was conducted. The study presents summary of large-scale fires in Mazovian Voivodship in 2015-2016 and its impact on environment. Location and dates of large-scale fires were compared with historical data of air monitoring available on State Inspectorate for Environmental Protection database. Impact of wildfires on environment was already described widely in literature, this approach is focused on commercial buildings fires. The substantial peaks were noticed at Inspectorate for Environmental Protection research stations when large-scale fires occurred, especially regarding fires with long duration. Large fires with short duration were not reflected significantly in air monitoring database.
