Development and applications of a soil geographic database: a case study in a deltaic environment under rice cultivation
land management soil database capability map dataset salinity Ebro Delta
2014/11/12
The chosen area of this case study is the northern part of the Ebro Delta in northeast Spain. It
used to be an unhealthy swamp until sixty to eighty years ago. Within a relatively short period,
thi...
The influence of soil moisture on threshold runoff generation processes in an alpine headwater catchment

2011/3/15
This study investigates the role of soil moisture on the threshold runoff response in a small headwater catchment in the Italian Alps that is characterised by steep hillslopes and a distinct riparian ...
Mapping surface soil moisture over the Gourma mesoscale site (Mali) by using ENVISAT ASAR data
Mapping surface soil moisture Gourma mesoscale ENVISAT ASAR
2011/3/15
The potentialities of ENVISAT ASAR (Advanced Synthetic Aperture Radar) multi-angle data for mapping surface soil moisture (SSM) in Sahelian rangelands are investigated at medium scale (30 000 km2). Th...
Desert shrub stemflow and its significance in soil moisture replenishment
Desert shrub stemflow soil moisture replenishment
2011/3/15
Stemflow of xerophytic shrubs represents a significant component of water replenishment to the soil-root system influencing water utilization of plant roots at the stand scale, especially in water sca...
Developing an improved soil moisture dataset by blending passive and active microwave satellite-based retrievals
Developing an improved soil moisture active microwave retrievals
2011/3/14
Combining information derived from satellite-based passive and active microwave sensors has the potential to offer improved estimates of surface soil moisture at global scale. We develop and evaluate ...
An inversion method based on multi-angular approaches for estimating bare soil surface parameters from RADARSAT-1
multi-angular approaches estimating bare soil surface parameters
2010/12/22
This paper focuses on inversion of these parameters using a multi-angular approach based on RADARSAT-1 data with incidence angles of 35° and 47° (in mode S3 and S7). This inversion was performed with ...
Cross-evaluation of modelled and remotely sensed surface soil moisture with in situ data in southwestern France
surface soil moisture situ data southwestern France
2010/12/22
The SMOSMANIA soil moisture network in Southwestern France is used to evaluate modelled and remotely sensed soil moisture products. The surface soil moisture (SSM) measured in situ at 5 cm permits to ...
Improving runoff prediction through the assimilation of the ASCAT soil moisture product
Improving runoff prediction the ASCAT soil moisture product
2010/12/22
The role and the importance of soil moisture for meteorological, agricultural and hydrological applications is widely known. Remote sensing offers the unique capability to monitor soil moisture over l...
A comparison of ASCAT and modelled soil moisture over South Africa，using TOPKAPI in land surface mode
ASCAT modelled soil moisture South Africa TOPKAPI land surface mode
2010/4/7
In this paper we compare two independent soil moisture estimates over South Africa. The first estimate is a Soil Saturation Index (SSI) provided by automated real-time computations of the TOPKAPI hydr...
Frozen soil parameterization in a distributed biosphere hydrological model
Frozen soil parameterization distributed biosphere hydrological model
2010/4/7
In this study, a frozen soil parameterization has been modified and incorporated into a distributed biosphere hydrological model (WEB-DHM). The WEB-DHM with the frozen scheme was then rigorously evalu...
