Astiani D, Mujiman, Curran LM. 2017. Trees of tropical peatland forest influence on variability of water and carbon input through stemflow. Biodiversitas 18: 383-388. Hydrology controls the chemical and biotic processes in peatlands, influencing interactions among vegetation, nutrient dynamics, and carbon fluxes. The effects of forest degradation revealed severe changes in the hydrological cycl...

Abstract Quantifying changes in hot temperature extremes is key for developing adaptation strategies. Changes are often determined on the basis of air temperatures; however, hydrology and many biogeochemical processes more sensitive to soil temperature. Here we show that increasing faster than by 0.7 °C per decade intensity twice as fast frequency average over Central Europe. Furthermore, ident...

Low-diversity ecosystems cover large portions of the Earth’s land surface, yet studies of climate change on ecosystem functioning typically focus on temperate ecosystems, where diversity is high and the effects of individual species on ecosystem functioning are difficult to determine. We show that a climate-induced decline of an invertebrate species in a low-diversity ecosystem could contribute...

The SWATDRAIN model was developed by incorporating the subsurface flow model, DRAINMOD, into a watershed scale surface flow model, SWAT (Soil and Water Assessment tool), to simulate the hydrology and water quality of agricultural watersheds. The model is capable of simulating hydrology under different agricultural management and climate scenarios. As an application of the SWATDRAIN model, the i...

Watershed management is based on the application of models to predict the probable outcome of hypothetical management scenarios. There is enormous variability in the type and complexity of models that are used. In research, the preference is for process-based distributed hydrologic simulation models such as “Distributed Hydrology-Soil-Vegetation Model” (DHSVM, Wigmosta et al., 1994), while the ...

{We describe a multiscale modeling framework applicable for a wide range of hydrologic processes. The foundation for this work has been laid by Basseville et al. 1992] and Chou et al. 1994]. Their development is based on treating the scale parameter akin to time, such that description at a particular scale captures the features of the process up to that scale that are relevant for the predictio...

Various applications such as meteorology, climatology or hydrology require information about the soil hydraulic properties over large areas. Microwave radiometry is a promising approach to gather this type of information. The microwave emission from soils is strongly affected by the roughness of the soil surface. This effect has therefore to be quantified to get a reasonable estimation of the h...

The role of meteorology, hydrology and atmospheric deposition on the temporal pattern of SO4 and NO3 concentrations was investigated for three streams draining alpine catchments in Northern Italy. The study sites lie on a gradient of atmospheric fluxes of SO4 and NO3 (from about 50 to 80 meq m−2 y−1, and from 40 to 90 meq m−2 y−1, respectively). As a consequence of the increasing N input, the t...
