Physical water deprivation at the midpoint level is assessed in water-related LCIA methods using water scarcity indicators (e.g., withdrawal-to-availability and consumption-to-availability) at the river basin scale. Although these indicators represent a great step forward in the assessment of water-use-related impacts in LCA, significant challenges still(More)
— A parameter identification problem for systems governed by first-order, linear hyperbolic partial differential equations subjected to periodic forcing is investigated. The problem is posed as a PDE constrained optimization problem with data of the problem given by the measured input and output variables at the boundary of the domain. By using the(More)
Soil moisture retrieval over irrigated grasslands using X-band SAR data combined with optical data acquired at high resolution. HAL is a multidisciplinary open access archive for the deposit and dissemination of scientific research documents, whether they are published or not. The documents may come from teaching and research institutions in France or(More)
The objective of this study was to analyze the sensitivity of radar signals in the X-band in irrigated grassland conditions. The backscattered radar signals were analyzed according to soil moisture and vegetation parameters using linear regression models. A time series of radar (TerraSAR-X and COSMO-SkyMed) and optical (SPOT and LANDSAT) images was acquired(More)

This paper analyzes concentration and velocity profiles measured in small irrigation canals in Pakistan. Theoretical profiles are developed and calibrated from field data. A procedure, applicable in any open channel, is proposed to make up complete profiles when only average values for the velocity and the concentration are known. These profiles are used to(More)
