Assessment of the hydrological effect of drought and fire events on evapotransp...
Hausler, MelanieDoutoramento em Engenharia Florestal e dos Recursos Naturais - Instituto Superior de Agronomia / UL; Until today, there is only little knowledge about the behavior of actual evapotranspiration (ETa) before and after wildfires in Portugal, which can be estimated from remote sensing techniques. In this thesis, an existing Simplified Two-Source Energy Balance model (STSEB) was adapted, based on moderate resolution...
Measuring and modelling soil evaporation in an irrigated olive orchard to impro...
Tezza, Luca; Hausler, Melanie; Conceição, Nuno; Ferreira, Maria IsabelThe aim of this study was to estimate soil evaporation (Es) in an intensive olive orchard. Measurements of Es were performed for 19 days using microlysimeters, during summers 2010, 2011 and 2012 in southeast Portugal. In order to relate each area type to radiation transmissivity, ground cover measurements were performed over the years. These data were used to calibrate and validate an empirical model for Es est...
Assessment of vegetation parameters in olive trees in the region of Alentejo. A...
Hausler, MelanieMestrado em Engenharia Agronómica - Instituto Superior de Agronomia; Vegetation parameters, as the leaf area index (LAI) and the ground cover (GC) are commonly related to biosphere processes, being used in models to estimate yield and crop water requirements. Several direct and indirect methods have been developed in the past decades to determine the LAI. However, a simple approach to assess this parameter is s...
