The objective of this study is to present a new application of optical and radar remote sensing with high spatial ( 10 m) and temporal (a few days) resolutions for the detection of tillage and irrigation operations. The analysis was performed for irrigated wheat crops in the semi-arid Tensift/Marrakech plain (Central Morocco) using three FORMOSAT-2 images and two ASAR images acquired within one...

The potential of FORMOSAT-2 and ENVISAT/ASAR for the monitoring of irrigated wheat crops over Tensift/Marrakech semi-arid plain in Morocco is investigated. The green leaf area index (GLAI) was obtained from time series of vegetation index acquired by the FORMOSAT-2 instrument with a 25% accuracy. This information was then incorporated into a canopy functioning model to provide spatial estimates...

The accuracy degree of extracted canopy latent heat from canopy net radiation is depending extremely to the proposed PriestleyTaylor approximation. This extracting canopy latent heat is an initial approximation to compute iteratively partitioned energy components to soil and vegetation using in Two Source Energy Balance (TSEB) Model. This approximation is using a PriestleyTaylor coefficient (αp...

This paper describes the setting and results of a real-time experiment of irrigation scheduling by a time series of optical satellite images under real conditions, which was carried out on durum wheat in the Haouz plain (Marrakech, Morocco), during the 2012/13 agricultural season. For the purpose of this experiment, the irrigation of a reference plot was driven by the farmer according to, mainl...

In this paper the applicability of the Monin–Obukhov similarity theory (MOST) over heterogeneous terrain below the blending height is investigated. This is tested using two large aperture scintillometers (LAS), in conjunction with aggregation schemes to infer area-averaged refractive index structure parameters. The two LAS were operated simultaneously over the oliveyard of Agdal, located near M...

Doctors and nurses spent about 8 hours a day inside urban health centres examining a large number of patients. To assess radiation dose due to the attached and unattached fractions of the short-lived alpha-emitting radon decay products from the inhalation of air by working personnel and patients, concentrations of these radionuclides as well as those of radon and thoron gases were measured in i...

BACKGROUND Despite the importance of the postnatal consultation, in Morocco, only 22% of women attended these consultations. The aim of this study was to identify associated factors with these consultations and offer suggestions to improve their use. METHODS This study was conducted in 2014 in Marrakech. A sample of women in reproductive age (15-49 yr) giving birth during 2013 year was enroll...

The performance of Concentrating Photovoltaic and Thermal (CPV/T) systems is also linked to climatic conditions. In this paper, the main purpose determine energy economic a line-focus CPV/T system used for residential user, considering three cities with different weather conditions: Amsterdam (The Netherlands), Marrakech (Morocco), Salerno (Italy). A modular configuration system, concentration ...

Building information modelling (BIM) is increasingly appropriate for infrastructure projects, and in particular transport infrastructure. It a digital solution that integrates the practices of construction industry facility management during whole life cycle. This integration possible through single tool, which 3D model. Nevertheless, BIM standards, such as foundation classes, are still pipelin...
