Abstract

Chapter 1 IntroductionChapter 2 Surface -subsurface soil moisture coupling Chapter 3 Subsurface soil moisture dynamics in a cultivated field Chapter 4 Can radar vegetation backscatter reflect root zone soil moisture?Chapter 5 Monitoring agricultural field trafficability using Sentinel-1 Chapter 6 Root zone soil moisture estimation using Random Forests

Estimation of field-scale soil moisture content and its uncertainties using Sentinel-1 satellite imagery

“…Within the context of the research project OWAS1S (Optimizing Water Availability with Sentinel-1 Satellites), functional evaluation of SMC information 8. Synthesis has been applied in the PhD theses by Carranza (2021) for agricultural water management and by for operational water management. Similar analyses could be performed with the SMC retrievals from this thesis.…”

“…Next to attempting to correct or mask for vegetation effects and focus on the soil signal, information may be extracted from the vegetation signal. For example, vegetation σ 0 signals were used to monitor vegetation water stress (Van Emmerik et al, 2017), SMC in the root zone (Carranza, 2021) and vegetation indices (Vreugdenhil et al, 2018).…”
