2011/3/15
This study investigates the role of soil moisture on the threshold runoff response in a small headwater catchment in the Italian Alps that is characterised by steep hillslopes and a distinct riparian ...
Implementing small scale processes at the soil-plant interface – the role of root architectures for calculating root water uptake profiles
small scale processes soil-plant interface root architectures root water uptake profiles
2010/2/20
In this paper, we present a stand alone root water uptake model called aRoot, which calculates the sink term for any bulk soil water flow model taking into account water flow within and around a root ...

democratisation decision-making processes water sector II
2009/12/4
The second part of this paper investigates one possibility of realising an inversion of the so-far established order of knowledge/power structures in that it corresponds to an inversion in power relat...
The democratisation of decision-making processes in the water sector I
democratisation decision-making processes water sector I
2009/12/4
The paper introduces an inversion of the structure of the decision making process in the water sector that has been so far followed in most countries, and in almost all so-called 'third world' societi...
Testing and modelling autoregressive conditional heteroskedasticity of streamflow processes
autoregressive conditional heteroskedasticity streamflow processes
2009/11/9
Conventional streamflow models operate under the assumption of constant variance or season-dependent variances (e.g. ARMA (AutoRegressive Moving Average) models for deseasonalized streamflow series an...
Particle dispersion processes in two-dimensional turbulence:a comparison with 2-D kinematic simulation
Particle dispersion processes two-dimensional turbulence 2-D kinematic simulation

We study numerically the comparison between Lagrangian experiments on turbulent particle dispersion in 2-D turbulent flows performed, on the one hand, on the basis of direct numerical simulations (DNS...
Mixing Processes in Lakes
Mixing Processes Lakes
2009/10/29
A review of the available methods for analyzing turbulent mixing in lakes is presented. The different types of flow are classified and their turbulence characteristics described. The diffusion caused ...
A spatially distributed model for the simulation of snow accumulation and
melt is presented. Watershed information on topography, vegetation and soils
in digital terrain models (overlays) serve as t...
