1. Aplicação de SEBAL e Ts/VI Trapézio Modelos para Estimar a Evapotranspiração Real no Ambiente do Argelino Semi-árido para Melhorar a Gestão da água na Agricultura
Resumo Estimativas precisas da evapotranspiração (ET) e dos fluxos de energia na superfície são cruciais para muitas aplicações agro ambientais, incluindo a determinação do balanço hídrico, manejo da irrigação, zoneamentos agro ecológicos, simulações de mudanças globais no uso da terra e previsão da produção de culturas agrícolas. Modelos

2. Land use and water quality in watersheds in the State of São Paulo, based on GIS and SWAT data
Resumo O uso e ocupação do solo influenciam a qualidade e a disponibilidade de água, devendo ser considerados numa gestão integrada dos recursos hídricos e no planejamento das bacias hidrográficas. Ferramentas de geoprocessamento têm sido utilizadas para classificação do uso do solo e combinadas com modelos hidrológicos para avaliação do impacto

3. SENSITIVITY OF EVAPOTRANSPIRATION ESTIMATED BY ORBITAL IMAGES UNDER INFLUENCE OF SURFACE TEMPERATURE
ABSTRACT Surface temperature (Ts) is a determining factor to obtain energy balance parameters, being relevant to understand the influence of this variable on the estimation of evapotranspiration. Thus, the objective of this study was to simulate errors in Ts estimation to verify the consequences of actual evapotranspiration (ETa) estimated by the SAFER (Simp

4. Análise do Desempenho do Modelo WRF num Episódio de Vento Intenso e Persistente num Grande Reservatório Tropical
Resumo O presente estudo apresenta uma aplicação do modelo de mesoescala WRF à simulação de um episódio de vento intenso e persistente que ocorre com frequência irregular no reservatório de Guapé, MG. Tal evento altera a rotina da população na região, fazendo com que, por exemplo, a embarcação que faz a travessia entre as cidades de Guapé e Ca

5. Spatial variability of coffee plant water consumption based on the SEBAL algorithm
ABSTRACT: Awareness of evapotranspiration (ET) and crop coefficient (Kc) is necessary for irrigation management in coffee crops. ET and Kc spatial variabilities are disregarded in traditional methods. Methods based on radiometric measurements have potential to obtain these spatialized variables. The Kc curve and spatial variability of actual evapotranspirati

6. Evaluation of OSEB and SEBAL models for energy balance of a crop area in a humid subtropical climate
ABSTRACT This study evaluated the adequacy of the One-Source Energy Balance (OSEB) and Surface Energy Balance Algorithm for Land (SEBAL) models to estimate evapotranspiration in grain growing areas with humid subtropical climate in Rio Grande do Sul, southern Brazil. The dataset was obtained from a micrometeorological station (Eddy Covariance) and MODIS (Mod

7. IMPLICATIONS FOR PEAK FLOWS OF THE MARRECAS RIVER BASIN DUE TO CHANGES IN THE BRAZILIAN FOREST CODE
ABSTRACT Changes in the Brazilian Forest Code (BFC) have soften the criteria for recovery and conservation of permanent preservation areas (PPAs), enhancing processes related to surface runoff. The aim of this study is to understand the effects of changes in PPA classification criteria established by BFC of 2012 to the detriment of BFC from 1965 considering

8. Effects of Soil Management Practices on Water Erosion under Natural Rainfall Conditions on a Humic Dystrudept
ABSTRACT Water erosion is the main cause of soil degradation and is influenced by rainfall, soil, topography, land use, soil cover and management, and conservation practices. The objective of this study was to quantify water erosion in a Humic Dystrudept in two experiments. In experiment I, treatments consisted of different rates of fertilizer applied to the

9. Anopheles fauna of coastal Cayenne, French Guiana: modelling and mapping of species presence using remotely sensed land cover data
Little is known about the Anopheles species of the coastal areas of French Guiana, or their spatiotemporal distribution or environmental determinants. The present study aimed to (1) document the distribution of Anopheles fauna in the coastal area around Cayenne, and (2) investigate the use of remotely sensed land cover data as proxies of Anopheles presence.

10. Quality Evaluation of Chromatic Interpolation Algorithms for Image Acquisition System
ABSTRACT The main goal of the Libertad 2 mission is to take images of the Earth’s surface in the visible spectrum with a multispectral sensor and send them as a Bayer array. To carry out the reconstruction in land of these images and to view them in a RGB color model, it is necessary to use a color interpolation algorithm to determine the values of the dif

11. Appraisal of Phlebotomus argentipes habitat suitability using a remotely sensed index in the kala-azar endemic focus of Bihar, India
Visceral leishmaniasis, or kala-azar, is recognised as a serious emerging public health problem in India. In this study, environmental parameters, such as land surface temperature (LST) and renormalised difference vegetation indices (RDVI), were used to delineate the association between environmental variables and Phlebotomus argentipes abundance in a repres
