Despite optical remote sensing (and the spectral vegetation indices) contributions to digital soil-mapping studies of soil organic carbon (SOC), few have used active radar mission data like that from synthetic aperture (SAR) sensors predict SOC. Bearing in mind importance SOC mapping for agricultural, ecological, and climate interests also recently developed methods monitoring using Sentinel-1 SAR data, this work, we aimed take advantage high operationality imaging test accuracy prediction...
In order to characterize the occurrence and intensity of droughts in Doce River Basin, as well develop a system for its classification, four different drought indexes were evaluated: Percent Normal Precipitation (PNP), Deciles Method (DM), Rainfall Anomaly Index (RAI) Standardized (SPI). The indices calculated annually, based on precipitation data from 89 rainfall stations Brazilian National Water Agency (ANA). Nine analysis units (AUs) determined basin Thiessen Polygons method was used...
The study was conducted in the Mortes River Basin (MRB), Mato Grosso State (Brazil), owing to constant removal of native forest (Brazilian Savannah, popularly known as Cerrado) for agriculture and pasture purposes. hydrological model large basins (MGB-IPH) employed assess impacts due land-use land-cover scenarios. Three scenarios were built according soil use capacity MRB (C1: Savannah recovery by areas, C2: expansion, C3: expansion). In general, C2 C3 results show an increase water...
A erosividade da chuva é um índice numérico que expressa a capacidade das chuvas em provocar erosão hídrica no solo. O presente trabalho teve por objetivo desenvolver programa computacional para estimar os valores Estado de Minas Gerais com base redes neurais artificiais (RNAs). valor anual obtido pelo somatório dos mensais índices EI30 ou KE > 25. Foram utilizados cálculo cada desses dois métodos obtenção energia cinética precipitação pluvial. Dessa maneira, obtiveram-se quatro mês,...
O conhecimento do valor da erosividade chuva (R) de determinada localidade é fundamental para a estimativa das perdas solo feitas partir Equação Universal Perdas Solo, sendo, portanto, grande importância no planejamento conservacionista. A fim obter estimativas R localidades onde este desconhecido, desenvolveu-se uma rede neural artificial (RNA) e analisou-se acurácia desta com o método interpolação "Inverso Potência Distância" (ID). Comparando RNA desenvolvida ID, verificou-se que primeira...
The rainfall parameter that expresses the capacity to promote soil erosion is called erosivity (R), and commonly represented by indexes EI30 KE>25. calculations of these requires pluviographical records, are difficult obtain in Brazil. This paper describes use synthetic series compute KE>25 Espírito Santo State (Brazil). Artificial neural networks (ANNs) were also developed spatially interpolate R values Santo. close those calculated on a homogeneous area according similarity...
O Brasil possui uma das mais modernas leis de gerenciamento recursos hídricos do mundo. Dentre seus instrumentos gestão e planejamento, a outorga dos direitos uso permite ao órgão gestor o controle quantitativo qualitativo hídricos. Considerando importância da como instrumento água, objetivo trabalho foi analisar alternativas critérios que considerem sazonalidade anual vazões, visando fornecer subsídios técnico-científicos para tomada decisão pelos órgãos gestores Os efeitos quantitativos...
