The redistribution of soil water by tree root systems
Oecologia, 1998Plant roots transfer water between soil layers of different water potential thereby significantly affecting the distribution and availability of water in the soil profile. We used a modification of the heat pulse method to measure sap flow in roots of Grevillea robusta and Eucalyptus camaldulensis and demonstrated a redistribution of soil water from ...

Redistributing Water Uses and Living with Scarcity
2004Water scarcity is probably one of the most salient problems in Spain. The combination of climate conditions, which are typical of the Mediterranean basin, together with the increase of rival uses of water during the last decades, have put water scarcity high on the political agenda.

Water Redistribution After Infiltration into the Soil
2019This chapter studies mainly the redistribution of rain or irrigation waters in the soil profile. It is shown that the main difficulty in the mathematical analysis is the hysteresis, because during the redistribution of water, part of the profile is under a wetting process and another part under a drying process.

Soil water hydraulic redistribution in a subtropical monsoon evergreen forest
Science of The Total Environment, 2022Hydraulic redistribution (HR), which is the passive movement of water through plant roots from wet to dry soil due to the water gradient, is important for plant physiology and ecohydrological processes. However, our poor knowledge on HR in the humid monsoon climate zone hampers the understanding of the interactions between vegetation and soil water ...

Water infiltration and redistribution in Land Surface Models [PDF]
, 2016 In this report, we examine the potential of integrated LandSurface Models that are part of Numerical Weather Prediction (NWP) systems to produce surface runoff in case of intense rainfall events. We chose to run two infiltration experiments using the SWAP, JULES and CHTESSEL models.

Local redistribution of fungicides on leaves by water
Annals of Applied Biology, 1970SUMMARYLocal redistribution of various fungicides applied as large or small droplets to detached broad‐bean leaflets was examined by laboratory bio‐assay with Botrytis fabae and by leaf‐printing techniques. The results showed that fungicidal particulate and soluble material will spread in water from the initial deposits and that the protected areas on ...

Post‐Irrigation Movement of Soil Water: 1. Redistribution
Water Resources Research, 1970Water content measurements by γ‐ray attenuation in soil columns were made during redistribution following irrigation. Approximate solutions of the unsaturated flow equation are derived that describe the water content above the initial wetting front as a function of time.

Modeling root water uptake: root water compensation and hydraulic redistribution
2017Root 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 Water and Soil Redistribution in a Dynamic Landscape Context
Soil Science Society of America Journal, 2002Soil suitability assessments for land use planning are commonly based on on‐site specific topographic, soil, and climatic characteristics, and are often neglecting the effects of physical landscape processes by water. The spatial and temporal variability of the landscape requires specific input data and modeling procedures.
