A compartmental model to describe hydraulics in a full-scale waste stabilization pond
(2012-02-01)
The advancement of experimental and computational resources has facilitated the use of computational fluid dynamics (CFD) models as a predictive tool for mixing behaviour in full-scale waste stabilization pond systems. ...
BEST-WR: An adapted algorithm for the hydraulic characterization of hydrophilic and water-repellent soils
(2021-12-01)
Water-repellent soils usually experience water flow impedance during the early stage of a wetting process followed by progressive increase of infiltration rate. Current infiltration models are not formulated to describe ...
Full thermal-hydraulic and solar modeling to study low-cost solar collectors based on a single long LDPE hose
(Pergamon-Elsevier Science Ltd, 2017-06)
A comprehensive analysis of low-cost solar collectors based on a single long plastic LDPE hose resting on a roof and working by thermosiphon is performed. This lay-out involves two challenging issues, high hydraulic ...
The Widened Pipe Model of plant hydraulic evolution
(Natl Acad Sciences, 2021-06-01)
Shaping global water and carbon cycles, plants lift water from roots to leaves through xylem conduits. The importance of xylem water conduction makes it crucial to understand how natural selection deploys conduit diameters ...
Coupled Thermo-Hydro-Mechanical Numerical Modeling of Evolving Fractures in Rocks
(Springer, 2021-04-22)
We present a numerical technique capable of handling evolving fractures in rocks triggered by coupled thermo-hydro-mechanical (THM) phenomena. The approach is formulated in the context of the finite-element method (FEM) ...
Integrating hydraulic, physicochemical and ecological models to assess the effectiveness of water quality management strategies for the River Cuenca in Ecuador
(2013-04-10)
During the past decades, the development and use of ecological models to predict the presence or absence of macroinvertebrates as water quality indicators for decision support in river management has gained a lot of interest. ...
Homeostasis in leaf water potentials on leeward and windward sides of desert shrub crowns: water loss control vs. high hydraulic efficiency
(Springer, 2013-03)
Phenotypic plasticity in morphophysiological leaf traits in response to wind was studied in two dominant shrub species of the Patagonian steppe, used as model systems for understanding effects of high wind speed on leaf ...
