“…Thus, although they differ significantly in vegetation cover, the soil properties of Arnás and Araguás_Afforestation are similar and result from intense agricultural practices in the past, a finding that may explain their similar hydrological responses under wet conditions. This is in accordance to Hümann et al (2011) who showed, in Southwest Germany, that soils under afforestation still possessed hydrological properties of the former agricultural land. The effect of the vegetation cover is evident under dry conditions, with much lower values of runoff in Araguás_Afforestation than in Arnás, even in response to a high intensity rainfall event (> 30 mm h -1 ).…”

ABSTRACT. Vegetation expansion following farmland abandonment is a complex process that depends on multiple natural and human-induced factors, resulting in differences in the evolution of land cover on former cultivated fields, with various environmental implications. To assess the complexity of the hydrogeomorphological consequences of farmland abandonment, the Instituto Pirenaico de Ecología (CSIC) and the University of La P A P E R A C C E P T E D .

“…Os dados foram trabalhados calculandose a vazão média mensal a partir de dados diários, convertendo-a em deflúvio, em mm, considerando-se as respectivas áreas de drenagem, para fins de comparação entre as sub-bacias hidrográficas. Na sequência, o deflúvio subterrâneo foi separado do superficial direto considerando-se o comportamento exponencial do primeiro, após identificação dos pontos de inflexão nas hidrógrafas (Hümann et al, 2011). Esse processo metodológico permite avaliar as condições de armazenagem de água subterrânea nos aquíferos superficiais, os quais interagem com a drenagem superficial e, consequentemente, estão vinculados ao processo de recarga subterrânea, caracterizando o estoque de água armazenada no período chuvoso.…”

A proposição de índices de qualidade do solo tem crescido de forma considerável nos últimos anos para análises de sustentabilidade ambiental e da produção agrícola. No entanto, não há, nas condições brasileiras, o desenvolvimento de qualquer indicador de qualidade do solo vinculado à recarga de água subterrânea. O objetivo deste estudo foi gerar um índice de qualidade do solo, relacionado à recarga de água subterrânea (IQS RA ), válido para as condições da Bacia Hidrográfica do Alto Rio Grande e proceder a seu mapeamento por meio de técnicas geoestatísticas. O IQS RA proposto é uma combinação linear de três indicadores relacionados à infiltração de água no solo: densidade do solo, condutividade hidráulica saturada e macroporosidade. Para sua validação, foi considerada a participação do deflúvio base (ou subterrâneo) no deflúvio total para quatro subbacias da Bacia Hidrográfica do Alto Rio Grande, analisando o comportamento desses indicadores hidrológicos tendo-se como referência a distribuição espacial do IQS RA . O índice gerado mostrou-se uma ferramenta importante para avaliação do potencial do solo para recarga de água subterrânea, uma vez que ele reflete a influência dos usos da terra no comportamento do deflúvio base e, consequentemente, na dinâmica da produção de água pelas sub-bacias.Termos de indexação: produção de água, hidrologia do solo, uso da terra, mapeamento.

“…All test plots within the catchments are forested, except for one arable field site at the Frankelbach catchment, which has been included for comparison. Each plot represents a typical part of the catchment, and it is assumed that all test plots combined represent the overall basin characteristics [15]. Another selection criterion was the accessibility of the test plots in order to conduct the very labor-intensive experiments in the best possible way.…”

“…During the Pleistocene, periglacial solifluidal processes were common in the low mountain ranges of Southwest Germany and the adjacent states [15]. Therefore, many soil profiles within the test sites are characterized by a densely stratified -basal layer‖ in the subsoil and a loose and permeable -main layer‖ in the topsoil [16][17][18].…”

At present it is common to use geographic information system (GIS) applications to assess runoff generation. One of these GIS-based tools to generate maps of dominant runoff processes is the so called GIS-DRP approach. The tool, which has been developed mainly based on agricultural areas, uses commonly available input data like a digital elevation model (DEM), geological information as well as land use information. The aim of this study is to test, validate and improve this GIS-DRP method for forested and silviculture areas. Hence, soil-hydrologic investigations and several mapping techniques of dominant runoff processes were conducted on 25 test-plots in four forested catchments in Rhineland-Palatinate (Germany) and the Grand Duchy of Luxembourg. By comparing the results of the mapping techniques and those of the test plots, weak points in the original GIS-DRP method were detected. Subsequently, it was possible to enhance the GIS-DRP approach by incorporating new discharge relevant parameters like topsoil sealing, extreme weather events and semipermeability of the substratum. Moreover, the improved GIS-DRP approach can be widely used in different landscapes and for different fields of application. The adapted method can now support foresters and decision makers in forestry planning, answer questions concerning the landscape water balance and peripheral water retention or provide extra information for sustainable forest planning in times of a changing climate.
