  text: Grassland and pastures are important land uses in subalpine and alpine environments.
    They are typically subjected to management practices that can change the biophysical
    structure of the canopy through defoliation and can alter soil hydraulic properties.
    These modifications have the potential to impact hydrological and energy fluxes
    as well as the primary productivity of grasslands. We investigate how a series
    of management practices, such as grass cut, grazing, and the consequent soil compaction
    due to treading by animals are affecting water resources, flood generation, and
    grassland productivity in a subalpine region. Results are obtained using a mechanistic
    ecohydrological model, Tethys-Chloris. The model is first confirmed using energy,
    water, and carbon fluxes measured at three eddy covariance stations over grasslands
    in Switzerland and discharge measured in a small experimental catchment. A series
    of virtual experiments are then designed to elucidate the importance of various
    management scenarios at the plot and catchment scales. Results show that only
    severe management actions such as low grass cuts or heavy grazing are able to
    influence considerably the long-term hydrological behavior. Moderate management
    practices are typically unable to modify the system response in terms of energy
    and water fluxes. An important short-term effect is represented by animal-induced
    soil compaction that can reduce infiltration capacity leading to peak flow considerably
    higher than in undisturbed conditions. The productivity of vegetation in absence
    of nutrient limitation is considerably affected by the different management scenarios
    with tolerable disturbances that lead to higher aboveground net primary production.

  text: High-resolution space-time stochastic models for precipitation are crucial
    for hydrological applications related to flood risk and water resources management.
    In this study, we present a new stochastic space-time model, STREAP, which is
    capable of reproducing essential features of the statistical structure of precipitation
    in space and time for a wide range of scales, and at the same time can be used
    for continuous simulation. The model is based on a three-stage hierarchical structure
    that mimics the precipitation formation process. The stages describe the storm
    arrival process, the temporal evolution of areal mean precipitation intensity
    and wet area, and the evolution in time of the two-dimensional storm structure.
    Each stage of the model is based on appropriate stochastic modeling techniques
    spanning from point processes, multivariate stochastic simulation and random fields.
    Details of the calibration and simulation procedures in each stage are provided
    so that they can be easily reproduced. STREAP is applied to a case study in Switzerland
    using 7 years of high-resolution (2 × 2 km2; 5 min) data from weather radars.
    The model is also compared with a popular parsimonious space-time stochastic model
    based on point processes (space-time Neyman-Scott) which it outperforms mainly
    because of a better description of spatial precipitation. The model validation
    and comparison is based on an extensive evaluation of both areal and point scale
    statistics at hydrologically relevant temporal scales, focusing mainly on the
    reproduction of the probability distributions of rainfall intensities, correlation
    structure, and the reproduction of intermittency and wet spell duration statistics.
    The results shows that a more accurate description of the space-time structure
    of precipitation fields in stochastic models such as STREAP does indeed lead to
    a better performance for properties and at scales which are not used in model
    calibration.

  text: 'Daily streamflow from stations close to five Swiss glaciers is analyzed for
    trends with the Mann-Kendall test. We consider a common period of record (1974–2004)
    and longer periods based on data availability. The trend statistical significance
    is tested on annual and seasonal bases. We also examine changes in precipitation,
    temperature, and snow cover characteristics. Highly glacierized basins show statistically
    significant positive trends in annual streamflow caused by increasing streamflow
    in spring and summer. Trends are more numerous and stronger at lower and mid than
    at the upper quantiles. The basin characterized by lower glacier coverage, conversely,
    does not exhibit consistently statistically significant trends. Changes in precipitation
    are not sufficient to explain the observed streamflow trends. Air temperature
    sees an increase in mean, minimum, and maximum values at all sites. Variations
    in the seasonal snow accumulation and ablation process are evident. Solid precipitation
    is decreasing at all sites and trends may be due to a shift from snowfall into
    rainfall. Mean snow depth is also decreasing, and its duration is getting shorter
    because of a decrease in solid precipitation and enhanced melting. Trend magnitude
    attenuates with longer time series. Contrasting trends are detected for different
    subperiods in the last 70 years: statistically significant negative trends are
    observed in the periods 1944–1974 and 1954–1984 for Aletschgletscher, in contrast
    with the results for the common period. These trends are explained by different
    rates of ice volume changes, and the sign of trends is clearly related to phases
    of positive or negative glacier mass balance.'

  text: <jats:p>By partitioning mass and energy fluxes, soil moisture exerts a fundamental
    control on basin hydrological response. Using the design characteristics of the
    Biosphere 2 hillslope experiment, this study investigates aspects of soil moisture
    spatial and temporal variability in a zero‐order catchment of a semiarid climate.
    The hydrological response of the domain exhibits a particular structure, which
    depends on whether topography‐induced subsurface stormflow is triggered. The occurrence
    of the latter is conditioned by topography, soil depth, and pre‐storm spatial
    distribution of moisture. As a result, a non‐unique behavior of soil moisture
    spatial heterogeneity emerges, manifested through a hysteretic dependence of variability
    metrics on mean water content. Further, it is argued that vegetation dynamics
    impose a “homogenizing” effect on pre‐storm moisture states, decreasing the likelihood
    that a rainfall event will result in topographic redistribution of soil water.
    Consequently, post‐rainfall soil moisture dynamics associated with the effect
    of topography that could lead to the enhancement of spatial heterogeneity are
    suppressed; a potential “attractor” of catchment states emerges. The study thus
    proposes several hypotheses that will be testable within the framework of long‐term
    hillslope experiments.</jats:p>
