Microscale Xylem Sap Flow Sensor Facilitating the Simultaneous Measurement of Flow Velocity and Direction

open access: yesProceedings, 2019
In this study, we focused on direct and quantitative monitoring of sap dynamics in plant stems, and proposed the microscale xylem sap flow sensor. This sensor facilitates the simultaneous measurement of flow velocity and direction by combining the ...

Configuration of Low-Cost Miniature Heat Pulse Probes to Monitor Heat Velocity for Sap Flow Assessments in Wheat (Triticum durum L.)

open access: yesGrasses
Heat velocity (Vh) is a key metric to estimate sap flow which is linked to transpiration rate and is commonly measured using thermocouples implanted in plant stems or tree trunks.

Observations of high-velocity SAPS-like flows with the King Salmon SuperDARN radar [PDF]

open access: yesAnnales Geophysicae, 2006
Abstract. In this study, a focused investigation of the potential for the King Salmon (KS) SuperDARN HF radar to monitor high-velocity flows near the equatorial edge of the auroral oval is undertaken. Events are presented with line-of-sight velocities as high as 2km/s, observed roughly along the L-shell.

Evaluation of the heat pulse velocity method for measuring sap flow inPinus patula [PDF]

open access: yesJournal of Experimental Botany, 1996
Information on the water use of Pinus patula plantations is required to predict the impact of forest plantations on water resources in South Africa. The heat pulse velocity (HPV) method is a promising technique for measuring water use by trees, and has been shown to measure sap flows accurately in a variety of hardwood trees.

Leaf photosynthetic capacity, trunk wood structure and stem xylem sap flow in 700-years old Quercus robur L.: a pilot study upon oak ‘Bartek’, a natural monument in Poland

open access: yesSilva Fennica, 2022
Physiological studies of long-lived trees are particularly important at this time, especially in light of the need for trees to adapt to global climate change.

Sap flow study on two different diameter sizes of Tectona grandis [PDF]

open access: yes, 2017
Sap flow pattern of Tectona grandis planted at lowland forest assessed. This study aimed to determine the sap movement of two different diameter sizes T. grandis. Two sizes selected were 16 and 38 cm in diameter at breast height (dbh).

Super-absorbent swellable polymer as grouting material for treatment of karst water inrush

open access: yesInternational Journal of Mining Science and Technology, 2021
Grouting is the most commonly used method to control water inrush in underground engineering. Traditional cement-based materials are easy to dilute and hard to coagulate under the influence of large flow and high-velocity water inrush.

A Mariotte-based verification system for heat-based sap flow sensors [PDF]

open access: yes, 2012
Determination of the accuracy of commonly used techniques for measuring sap flux density in trees often presents a challenge. We therefore designed and built a verification system for heat-based sap flow sensors typically used at stem level.

Hydraulic lift in Populus euphratica Oliv. from the desert riparian vegetation of the Tarim River Basin [PDF]

open access: yes, 2010
In the Tarim River Basin, the desert riparian forest vegetation is under high-temperature and aridity stress However, the vegetation can grow continuously because of deep rooting that can reach groundwater, which can thus redistribute water into the ...
