The present study highlights the potential of multi-temporal X-band Synthetic Aperture Radar (SAR) moisture products to be used for the calibration of a model reproducing soil moisture (SM) variations. We propose the MHYSAN model (Modèle de bilan HYdrique des Sols Agricoles Nus) for simulating soil water balance of bare soils. This model was used t...
The purpose of the study is to verify whether some correlation exists between soil erodibility (i.e. K factor mentioned in RUSLE model) and data obtained from satellite images. This piece of work represents a first attempt towards a model that would predict the risk for soil erosion, from information contained in satellite images. Ouarchoch is a ru...
The aim of this paper is to propose a methodology combing multi-temporal X-band SAR images (TerraSAR-X) with continuous ground thetaprobe measurements, for the retrieval of surface soil moisture and texture at a high spatial resolution. Our analysis is based on seven radar images acquired at a 36° incidence angle in the HH polarization, over a semi...
Economical pressure on production and export of natural rubber leads to continuous expansion of rubber tree plantations in Thailand, even in areas, where climatic and environmental conditions are not optimal. In North-East Thailand the sandy textured soils are widespread. They are characterized by their weak structure and low cohesion between grain...
The objective of this paper is to analyze the sensitivity of very high resolution TerraSAR-X radar data to surface soil parameters over bare soils, and their spatial variability at a fine scale (within field plot). The relationship between the backscattering coefficient and soil parameters (moisture, surface roughness, soil texture and local topogr...
