Recent efforts have been concentrated in the development of models to understand and predict the impact of environmental changes on hydrological cycle and water resources in arid and semi-arid regions. In this context, remote sensing data have been widely used to initialize, to force or to control the simulations of these models. However, for several(More)
Dynamics of snow in semi-arid mountains are poorly investigated despite the fact that snow may represent an important source of water for downstream populations especially in the spring and early summer. Data acquired by space-borne optical sensors (i.e. reflectance and derived snow indices) may be suitable for spatial and temporal monitoring of snow cover.(More)
The aim of this study was to use the FAO-56 single and dual crop coefficient approaches to estimate actual evapotranspiration (ET a) over an irrigated citrus orchard under drip and flood irrigations in Marrakech, Morocco. The results showed that, by using crop coefficients suggested in the FAO-56 paper, the performance of both approaches was poor for two(More)
a r t i c l e i n f o One of the most serious environmental issues related to mining industry in Morocco and elsewhere around the world, is the pollution from abandoned mine sites. Mine wastes cause obvious sources of soil contaminations. Climatic effects such as heavy rainfall engender metal dispersion in semi-arid areas, since soils are typically and(More)
In arid and semi-arid areas, rainfall is often characterized by a strong spatial and temporal variability. These environmental factors, combined with the sparsity of the measurement networks in developing countries, constitute real constraints for water resources management. In recent years, several spatial rainfall measurement sources have become(More)
11 Understanding the spatial distribution of air temperature in mountainous areas is essential in 12 hydrological modelling. In the Moroccan High-Atlas range, the meteorological stations network 13 is sparse. In order to get additional information, we investigated the thermal infrared data 14 supplied by the Enhanced Thematic Mapper (ETM+) sensor onboard(More)
