Soil moisture gradients and controls on a southern Appalachian hillslope from drought through recharge
Soil moisture watersheds
2009/5/27
Soil moisture gradients along hillslopes in humid watersheds, although indicated by vegetation gradients and by studies using models, have been difficult to confirm empirically. While soil properties...
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...
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...
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 ...
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 ...
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...
Predictions of rainfall-runoff response and soil moisture dynamics in a microscale catchment using the CREW model
rainfall-runoff response microscale catchment soil moisture dynamics
2009/5/7
Predictions of catchment hydrology have been performed generally using either physically based, distributed models or conceptual lumped or semi-distributed models. In recognition of the disadvantages...
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...
On the comparison between the LISFLOOD modelled and the ERS/SCAT derived soil moisture estimates
soil moisture estimates root mean square
2009/5/6
In order to evaluate the reliability of the soil moisture product obtained by means of the LISFLOOD hydrological model (De Roo et al., 2000), we compare it to soil moisture estimates derived from ERS ...
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...
Comparison of soil moisture fields estimated by catchment modelling and remote sensing：a case study in South Africa
soil moisture catchment modelling remote sensing
2009/5/4
The paper compares two independent approaches to estimate soil moisture at the regional scale over a 4625 km2 catchment (Liebenbergsvlei, South Africa). The first estimate is derived from a physically...
Generation of soil moisture patterns at the catchment scale by EOF interpolation
Empirical Orthogonal Function soil moisture
2009/4/28
Spatial patterns of soil moisture cannot be adequately characterized by direct measurement for most practical applications, so interpolation between observations is required. Interpolation of soil moi...
Soil moisture retrieval through a merging of multi-temporal L-band SAR data and hydrologic modelling
Soil moisture synthetic aperture radar moisture content
2009/4/28
The objective of the study is to investigate the potential of retrieving superficial soil moisture content (mv) from multi-temporal L-band synthetic aperture radar (SAR) data and hydrologic modelling....
