Retrieving the irrigation actually applied at district scale: Assimilating high-resolution Sentinel-1-derived soil moisture data into a FAO-56-based model

Autor: Pierre Laluet, Luis Enrique Olivera-Guerra, Víctor Altés, Giovanni Paolini, Nadia Ouaadi, Vincent Rivalland, Lionel Jarlan, Josep Maria Villar, Olivier Merlin

Publikováno v: Agricultural Water Management, Vol 293, Iss , Pp 108704- (2024)

Irrigation is the most water consuming activity in the world. Knowing the timing and amount of irrigation that is actually applied is therefore fundamental for water managers. However, this information is rarely available at all scales and is subject

Publikováno v: Remote Sensing, Vol 13, Iss 16, p 3181 (2021)

Monitoring agricultural crops is of paramount importance for preserving water resources and increasing water efficiency over semi-arid areas. This can be achieved by modelling the water resources all along the growing season through the coupled water

Analysis of the impact of different irrigation scenarios on the water balance of the Ebro River Basin by means of a LSM and remote sensing irrigation estimations

Irrigation consumes around 70% of the world’s freshwater and has a significant impact on the continental water and energy cycles of the basins where it is present. Despite the clear benefits of irrigation, it has a strong impact on the continental

Estimating the drainage of irrigated areas: a combined crop water balance modeling and remote sensing approach

Autor: Pierre Laluet, Luis Enrique Olivera Guerra, Victor Altés Gaspar, Vincent Rivalland, Vincent Simonneaux, Vincent Bustillo, Joaquim Bellvert, Josep Maria Villar, Olivier Merlin

Drainage is the water flowing under the roots when the soil's capacity to hold water is exceeded. It is an important term of the crop water budget, controlling soil salinization, potentially impacting downstream ecosystems, and being a strong indicat

The modeling of irrigation in land surface models are generally based on two soil moisture parameters SMthreshold and SMtarget at which irrigation automatically starts and stops, respectively. Typically, both parameters are usually set to optimal val

Publikováno v: ISPRS Journal of Photogrammetry and Remote Sensing. 128:170-181

Monitoring evapotranspiration in arid and semi-arid environments plays a key role in water irrigation scheduling for water use efficiency. This work presents an operational method for evapotranspiration retrievals based on disaggregated Land Surface

A precise estimate of the evapotranspiration (ET) partitioning is fundamental for determining the crop water needs and optimizing irrigation management. The plant transpiration (T) is generally considered to be the most desirable component, while red
