Tree root systems competing for soil moisture in a 3D soil–plant model

Gabriele Manoli, Sara Bonetti, Gabriel George Katul

Competition for water among multiple tree rooting systems is investigated using a soil–plant model that accounts for soil moisture dynamics and root water uptake (RWU), whole plant transpiration, and leaf-level photosynthesis. The model is based on a numer ...

Hydrological and thermal response modeling based on travel time formulation of water and energy transport in snow-covered Alpine catchments

Andrea Rinaldo, Michael Lehning, Bettina Schaefli, Francesco Comola

In our contribution we present a semi-distributed model for thermo-hydrologic simulations of snow-covered alpine catchments, based on the travel time formulation of water and energy transport at sub-catchment scale. The output consists of distributed infor ...

Mind the gap: a new insight into the tip leakage vortex using stereo-PIV

Mohamed Farhat, Cécile Münch-Alligné, Matthieu Dreyer

The tip leakage vortex (TLV), which develops in the clearance between the rotor and the stator of axial hydro turbines, has been studied for decades. Yet, many associated phenomena are still not understood. For instance, it remains unclear how the clearanc ...

Modelling of groundwater-vegetation interactions in a tidal marsh

David Andrew Barry

Wetting and drying due to tidal fluctuations affect soil conditions and hence plant growth in tidal marshes. Here, a coupled one-dimensional model was developed to simulate interacting groundwater flow and plant growth in these wetlands. The simulation res ...

Phytoextraction of zinc, zinc oxide, copper and copper oxide in hydroponic solution with gibberellic acid and EDDS amendments by Lolium perenne

Flore Alice Margot Dupuich

This work was focused on the phytoextraction of zinc, copper, zinc oxide and copper oxide by Lolium perenne cultivated in hydroponic conditions, with gibberellic acid (GA) and ethylenediamine-N,N’-disuccinic acid (EDDS) amendments tested separately and in ...

An analytical model for soil-atmosphere feedback

Bettina Schaefli

Soil-atmosphere feedback is a key for understanding the hydrological cycle and the direction of potential system changes. This paper presents an analytical framework to study the interplay between soil and atmospheric moisture, using as input only the boun ...

Scaling study of cavitation pitting from cavitating jets and ultrasonic horns

Ayat Karimi, Jean-Pierre Franc

Cavitation erosion prediction and characterization of cavitation field strength are of interest to industries suffering from cavitation erosion detrimental effects. One means to evaluate cavitation fields and materials is to examine pitting rates during th ...

Evaluation of the hydrodynamic pressure of cavitation impacts from stress-strain analysis and geometry of individual pits

Ayat Karimi, Davide Carnelli, Jean-Pierre Franc

The present paper focuses on the development of an inverse procedure able to infer the hydrodynamic pressure distribution acting on the material surface and responsible for the creation of the cavitation pit based on the stress in a cavitation pit and its ...

Metabolic principles of river basin organization

Andrea Rinaldo

The metabolism of a river basin is defined as the set of processes through which the basin maintains its structure and responds to its environment. Green (or biotic) metabolism is measured via transpiration and blue (or abiotic) metabolism through runoff. ...
