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...
Analysis of soil water dynamics in an agroforestry system based on detailed soil water records from time-domain reflectometry
soil water dynamics time-domain reflectometry agroforestry system
2009/5/27
Time domain reflectometry [TDR] was used to investigate the spatial and temporal variation in surface soil water dynamics under a number of types of vegetation, including both trees and crops grown in...
The role of spatial variability of soil moisture for modelling surface runoff generation at the small catchment scale
soil moisture surface runoff generation small catchment scale
2009/5/27
A Bayesian approach is described for dealing with the problem of infilling and generating stochastic flow sequences using rainfall data to guide the flow generation process, and including bounded (ce...
Ditch water levels manages for environmental aims：effects on field soil water regimes
field soil water regimes ditch water management pump drainage
2009/5/26
The effects of ditch water management regimes on water tables are examined for two test sites in England, Halvergate in the Broads and Southlake Moor in the Somerset Levels and Moors Environmentally S...
Examination of evaporative fraction diurnal behaviour using a soil-vegetation model coupled with a mixed-layer model
evaporative fraction soil-vegetation model mixed-layer model
2009/5/26
In many experimental conditions, the evaporative fraction, defined as the ratio between evaporation and available energy, has been found stable during daylight hours. This constancy is investigated ov...
Rainfall input generation for the European Soil Erosion Model
Rainfall input European Soil Erosion Model rainfall event parameters
2009/5/26
A procedure to generate rainfall input for the EUROpean Soil Model is presented. To develop such a procedure, first of all the influence of rainfall event amount, rainfall event duration, and time to ...
The impact of broadleaved woodland on water resources in lowland UK：I. Soil water changes below beech woodland and grass on chalk sites in Hampshire
water resources broadleaved woodland grass
2009/5/18
The possible effects of broadleaved woodland on recharge to the UK Chalk aquifer have led to a study of evaporation and transpiration from beech woodland (Black Wood) and pasture (Bridgets Farm), grow...
A fast TDR-inversion technique for the reconstruction of spatial soil moisture content
soil moisture TDR-inversion technique
2009/5/18
Spatial moisture distribution in natural soil or other material is a valuably information for many applications. Standard measurement techniques give only mean or punctual results. Therefore a new inv...
Comparative analysis of the actual evapotranspiration of Flemish forest and cropland, using the soil water balance model WAVE
water use Flemish forest evapotranspiration soil water balance
2009/5/18
This paper focuses on the quantification of the green – vegetation related – water flux of forest stands in the temperate lowland of Flanders. The underlying reason of the research was to develop a me...
Soil moisture-runoff relation at the catchment scale as observed with coarse resolution microwave remote sensing
Soil moisture runoff relation catchment scale microwave remote sensing
2009/5/18
Microwave remote sensing offers emerging capabilities to monitor global hydrological processes. Instruments like the two dedicated soil moisture missions SMOS and HYDROS or the Advanced Scatterometer ...
Uncertainty in soil physical data at river basin scale – a review
soil physical river basin scale
2009/5/15
For hydrological modelling studies at the river basin scale, decision makers need guidance in assessing the implications of uncertain data used by modellers as an input to modelling tools. Simulated ...
Simplified stochastic soil-moisture models：a look at infiltration
soil-moisture models infiltration rainfall
2009/5/15
A simplified, vertically-averaged model of soil moisture interpreted at the daily time scale and forced by a stochastic process of instantaneous rainfall events is compared with a vertically-averaged ...
Novel evaporation experiment to determine soil hydraulic properties
soil hydraulic properties vapour flux
2009/5/15
A novel experimental approach to determine soil hydraulic material properties for the dry and very dry range is presented. Evaporation from the surface of a soil column is controlled by a constant fl...
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...

soil field experiment solute transport
2009/5/13
A classical transport experiment was performed in a field plot of 2.5 m2 using the dye tracer brilliant blue. The measured tracer distribution demonstrates the dominant role of the heterogeneous soil ...
