Modeling root water uptake: root water compensation and hydraulic redistribution

2017
Root water uptake by plants mediates the exchange of water, carbon and energy between land surface and atmosphere and is important in hydrological, climatological, agricultural and ecological studies. Field measurements show that root water uptake could be significantly affected by root water compensation and hydraulic redistribution.

Modeling Root Water Uptake in Hydrological and Climate Models

Bulletin of the American Meteorological Society, 2001
Abstract From 30 September to 2 October 1999 a workshop was held in Gif–sur–Yvette, France, with the central objective to develop a research strategy for the next 3–5 years, aiming at a systematic description of root functioning, rooting depth, and root distribution for modeling root water uptake from local and regional to global scales.

Sprinkler Irrigation, Roots and the Uptake of Water

1990
Clearer perception and better modelling of soil water and chemical flow will be aided by improved measurement of the appropriate saturated and unsaturated flow characteristics of field soil. In situ measurements, at and near saturation are presented for two contrasting soils: the herbicided, coarse soil of an apple orchard, and a biologically-active ...

Root water uptake and profile soil water as affected by vertical root distribution

Plant Ecology, 2006
Water uptake by plant roots is a main process controlling water balance in field profiles and vital for agro-ecosystem management. Based on the sap flow measurements for maize plants (Zea mays L.) in a field under natural wet- and dry-soil conditions, we studied the effect of vertical root distribution on root water uptake and the resulted changes of ...

Calibration of a Two‐Dimensional Root Water Uptake Model

Soil Science Society of America Journal, 2001
Although solutions of multidimensional transient water flow can be obtained by numerical modeling, their application may be limited in part as root water uptake is generally considered to be one‐dimensional only. The objective of this study was to develop and test a two‐dimensional root water uptake model, which can be incorporated

Water uptake in the root system of Gramineae

1989
Recent interest in modelling the water relations of plants has revealed gaps in the experimental information needed for a full description of water uptake by a complete root system. Calculating rates of water uptake by root systems requires not only knowledge of the demands placed on the root system by the shoot together with the magnitude of the water
