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...
Vegetation dynamics and soil water balance in a water-limited Mediterranean ecosystem on Sardinia, Italy
Vegetation dynamics Mediterranean ecosystem soil water balance
2009/5/6
Mediterranean ecosystems are commonly heterogeneous savanna-like ecosystems, with contrasting plant functional types (PFTs, e.g. grass and woody vegetation) competing for water. Mediterranean ecosyste...
Suitability of soil bioengineering techniques in Central America：a case study in Nicaragua
soil bioengineering techniques Central America
2009/5/6
In the last few years "D. I. A. F." (Department of Agriculture and Forestry Engineering of Florence University), has been testing the effectiveness of soil bioengineering techniques in Central America...
A conceptual dynamic vegetation-soil model for arid and semiarid zones
vegetation-soil model semiarid zones arid
2009/5/6
Plant ecosystems in arid and semiarid climates show high complexity, since they depend on water availability to carry out their vital processes. In these climates, water stress is the main factor cont...
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...
Analysis of soil and vegetation patterns in semi-arid Mediterranean landscapes by way of a conceptual water balance model
semi-arid Mediterranean water balance model vegetation types
2009/5/4
This paper investigates the impact of various vegetation types on water balance variability in semi-arid Mediterranean landscapes, and the different strategies they may have developed to succeed in su...
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...
Vegetation composition and soil microbial community structural changes along a wetland hydrological gradient
phospholipid fatty acid soil microbial Vegetation composition
2009/4/28
Fluctuations in wetland hydrology create an interplay between aerobic and anaerobic conditions, controlling vegetation composition and microbial community structure and activity in wetland soils. In t...
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 ...
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...
