“…These studies are mostly based on a model, which describes a biophysical system. Model simulations are widely used and unique tools for risk assessment, planning of adaptation measures and scenario analyses to assess the combined effects of land use, agricultural practices, and climate change on soil and water quality (Even & Parkin 1996;Hanel et al 2012;Mori et al 2013;Nikodem et al 2013;Jian et al 2014). Process-based models, describing physical processes of the investigated system have the ability to simulate variables under altered future conditions, supposing that the current physical relations remain valid under changing conditions.…”

A mathematical model was applied for the Bükk Mountains (Hungary) to evaluate the effects of climate change on soil water balance elements and soil water regime. Model runs using SWAP model were performed for combinations of four distinctive soil types and three land use systems of arable land, grassland, and forest. The temporal variation of soil water regime under changing climatic conditions was examined considering no land cover change occurring in the future. The climate data consisted of the predictions of two regional climate models, the Swiss CLM and the Swedish RCA. The RCA results showed 45% to 50% and the CLM showed 5% to 14% higher future precipitation outlook compared to present conditions. Considering different land use types, the projected number of days with soil moisture deficit was the highest in forest ecosystems for both the upper 50 cm soil layer and the whole soil profile, which could be as high as 61% of days below optimal soil water content range. Our results showed increased water fluxes, especially in deep percolation in far future period and a strong influence of soil properties on the changes in the climate model results, indicating significant long-term effects of climate change on soil water regime.

“…They found that (i) runoff coefficients during the first 7 months following the wildfire were similar for the Pine and the Eucalypt plantation, (ii) observed/inferred annual erosion rates over the first two years following the wildfire were also comparable at the two study sites, (iii) terracing seemed to enhance overland flow generation, and (iv) terracing appeared to increase erosion rates at both study sites by at least one order of magnitude. Mori et al (2013) analysed data on soil water content obtained on a steep slope near a ridge in a forested mountain range in south-western Japan. They constructed a simple prediction model by improving the "bucket with a bottom hole" model, and applied it to experimental data obtained on a forested slope to simulate the dynamics of soil moisture beneath the forest floor.…”

Biohydrology gives a new view on hydrological research. The impact of biota on hydrological processes was a disregarded topic in the early years of hydrology research. It has been present since the 1960s, but as a "Cinderella" research topic. It emerged as a new aspect of the hydrological processes after the 1980s. In the 21st century, it has become a well established research topic, bringing new knowledge to aid understanding on how biota influence the hydrological cycle and the rates of hydrological processes. The importance of biohydrology research is growing, and the number of conferences, publications and research projects is being doubled every decade.The 4th Biohydrology conference, held in Landau on 21-24 May 2013, addressed many contemporary issues surrounding water scarcity, climate change and increased pressure on land. Under the motto "Bio Meets Hydrology", it has brought together ideas and conceptions of environmental specialists from biological, chemical and physical sciences with the hydrological sciences to discuss and to merge methods and conceptions. The conference focussed on the interaction between biological and hydrological systems, including positive impacts such as water harnessing and flood mitigation, and negative aspects including threats to food production, water repellency and environmental degradation through unsustainable land use practices. In this forum, designed to get different disciplines working together, experts from hydrology, ecology, soil science, biology, geography, forestry and engineering met, and acquired new ideas for their research. Results of the most recent and advanced biohydrology research published in Special sections on biohydrology in Biologia 2013 and 2014, as well as in the Journal of Hydrology and Hydromechanics, are presented in this preface to the Thematic issue on biohydrology.The impact of vegetation cover on soil hydrological processes was the most frequent theme studied. In the first of 6 papers dealing with the biological soil crust (BSC), Cantón et al. (this issue) evaluated the dynamics of organic carbon (OC) losses by water erosion as affected by BSC. Runoff and erosion rates, dissolved organic carbon (DOC) and organic carbon bonded to sediments (S d OC) were measured during the simulated rain. The results showed different S d OC and DOC for the different BSCs and also that the presence of BSCs substantially decreased total organic carbon (TOC) compared to physical soil crusts. Within BSCs, TOC losses decreased as BSCs developed, and erosion rates were lower. Crust removal caused a strong increase in water erosion and TOC losses. Drahorad et al. (2013) estimated the changes in surface structure and wettability during BSC development on Arenosols. They found an increase in water repellency and a decrease in water sorptivity and conductivity with ongoing BSC succession. Penetration resistance data showed very stable thin surface protection by cyanobacteria in early successional BSC that is non-repellent. Later successional stages (lichen and mosses...
