Upscaled soil hydraulic properties are needed for many large-scale hydrologic applications such as regional and global climate studies and investigations of land–atmosphere interactions. Many larger scale subsurface flow and contaminant transport studies also require upscaled hydraulic property estimates. The objectives of this study were to develop a methodology for upscaling hydraulic propert...

The control of plant transpiration by stomata under water stress and recovery conditions is of paramount importance for plant performance and survival. Although both chemical and hydraulic signals emitted within a plant are considered to play a major role in controlling stomatal dynamics, they have rarely been assessed together. The aims of this study were to evaluate (i) the dynamics of chemic...

Hydraulic systems are widely used in industry because of the advantages of their small size-to-power ratios and their ability to produce very large linear force and torque. There are tendencies for compact electro-hydraulic systems which deliver powerful, linear movement having hydraulic oil circulation only when operating. This paper investigates directly driven hydraulic setup for non-road mo...
