Implementing small scale processes at the soil-plant interface – the role of root architectures for calculating root water uptake profiles
small scale processes soil-plant interface root architectures root water uptake profiles
2010/2/20
In this paper, we present a stand alone root water uptake model called aRoot, which calculates the sink term for any bulk soil water flow model taking into account water flow within and around a root ...

Formulation of root water uptake in a multi-layer soil-plant model：does van den Honert's equation hold?
root water uptake multi-layer soil-plant model
2009/5/27
The withdrawal of water from soil by vegetation, which in steady state conditions is equivalent to the transpiration rate, can be written in terms of water potential in the form of an Ohm's law analog...
Estimating spatial mean root-zone soil moisture from point-scale observations
soil moisture point-scale spatial mean
2009/5/15
Root zone soil moisture is a key variable in many land surface hydrology models. Often, however, there is a mismatch in the spatial scales at which models simulate soil moisture and at which soil moi...
Analysis of surface and root-zone soil moisture dynamics with ERS scatterometer and the hydrometeorological model SAFRAN-ISBA-MODCOU at Grand Morin watershed (France)
soil moisture dynamics hydrometeorological model
2009/5/6
Spatial and temporal variations of soil moisture strongly affect flooding, erosion, solute transport and vegetation productivity. Its characterization, offers an avenue to improve our understanding of...
From near-surface to root-zone soil moisture using an exponential filter：an assessment of the method based on in-situ observations and model simulations
soil moisture exponential filter
2009/5/6
A long term data acquisition effort of profile soil moisture is under way in southwestern France at 13 automated weather stations. This ground network was developed in order to validate remote sensing...
An optimality-based model of the coupled soil moisture and root dynamics
soil moisture root dynamics
2009/5/4
The main processes determining soil moisture dynamics are infiltration, percolation, evaporation and root water uptake. Modelling soil moisture dynamics therefore requires an interdisciplinary approac...
A model for hydraulic redistribution incorporating coupled soil-root moisture transport
soil-root moisture hydraulic redistribution
2009/4/28
One of the adaptive strategies of vegetation, particularly in water limited ecosystems, is the development of deep roots and the use of hydraulic redistribution which enables them to make optimal use ...
Towards understanding tree root profiles: simulating hydrologically optimal strategies for root distribution
forest hydrology optimisation roots
2009/3/24
In this modelling study differences in vertical root distributions measured in four contrasting forest locations in the Netherlands were investigated. Root distributions are seen as a reflection of th...
Root selection methods in flood analysis
unit hydrograph identification methods z-transform
2009/3/12
In the 1970s, de Laine developed a root-matching procedure for estimating unit hydrograph ordinates from estimates of the fast component of the total runoff from multiple storms. Later, Turner produce...
