The hydraulic bump: The surface signature of a plunging jet [PDF]

open access: yes, 2013
When a falling jet of fluid strikes a horizontal fluid layer, a hydraulic jump arises downstream of the point of impact provided a critical flow rate is exceeded.

Uncertainty in the determination of soil hydraulic parameters and its influence on the performance of two hydrological models of different complexity [PDF]

open access: yes, 2009
Data of soil hydraulic properties forms often a limiting factor in unsaturated zone modelling, especially at the larger scales. Investigations for the hydraulic characterization of soils are time-consuming and costly, and the accuracy of the results ...

Distribution of xylem hydraulic resistance in fruiting truss of tomato influenced by water stress [PDF]

open access: yes, 2003
In this study xylem hydraulic resistances of peduncles (truss stalk), pedicels (fruit stalk) and the future abscission zone (AZ) halfway along the pedicel of tomato (Lycopersicon esculentum L.) plants were directly measured at different stages of fruit ...

Exploring aquaporin functions during changes in leaf water potential

open access: yesFrontiers in Plant Science, 2023
Maintenance of optimal leaf tissue humidity is important for plant productivity and food security. Leaf humidity is influenced by soil and atmospheric water availability, by transpiration and by the coordination of water flux across cell membranes ...

Hydraulic flow through a channel contraction: multiple steady states [PDF]

open access: yes, 2007
We have investigated shallow water flows through a channel with a contraction by experimental and theoretical means. The horizontal channel consists of a sluice gate and an upstream channel of constant width $b_0$ ending in a linear contraction of ...

Thermes privés et publics dans le territoire éduen et ses marges : réexamen de quelques fouilles anciennes

open access: yesRevue Archéologique de l’Est, 2021
The public and private baths in the Eduen territory have been studied on a large scale and are generally well documented. Based on the Narbonnaise typology, it is possible to reconstruct the thermal system in the baths of other provinces and cities, such

In situ mixing of organic matter decreases hydraulic conductivity of denitrification walls in sand aquifers [PDF]

open access: yes, 2008
In a previous study, a denitrification wall was constructed in a sand aquifer using sawdust as the carbon substrate. Ground water bypassed around this sawdust wall due to reduced hydraulic conductivity.
