Mimoso Alluvial Valley, Semiarid Brazil. This study aims to assess the influence of climate variability and exploitation on groundwater accessibility, quantity quality, based a spatiotemporal data analysis from long-term monitoring field campaigns, conducted monthly 2000 2019. successfully identified representative stable points, piezometers wells, for piezometric salinity levels employing technique relative differences, taking into account aquifer hydraulic properties. Trend was then...
As mudanças no uso e na ocupação do solo, provocadas pelas ações antrópicas, têm gerado grandes impactos nas paisagens. Esses podem ser mitigados através monitoramento da cobertura solo utilizando-se informações espaço-temporais das modificações ocorridas paisagem. Este trabalho apresenta uma análise espaço-temporal detalhada dinâmica bacia hidrográfica riacho São Paulo, localizada região semiárida Estado de Pernambuco, entre os anos 1991 2010. Partindo classificação três imagens satélite...
Knowledge about soil moisture dynamics and their relation with rainfall, evapotranspiration, physical properties is fundamental for understanding the hydrological processes in a region. Given difficulties of measurement scarcity surface data some places such as Northeast Brazil, modelling has become robust tool to overcome limitations. This study investigated water content two plots Gameleira Experimental River Basin, Brazil. For this, Time Domain Reflectometry (TDR) probes Hydrus-1D...
Abstract Although cosmic‐ray neutron sensing (CRNS) is probably the most promising noninvasive proximal soil moisture measurement technique at field scale, its application for hydrological simulations remains underexplored in literature so far. This study assessed use of CRNS to inversely calibrate hydraulic parameters intermediate scale simulate groundwater recharge rates a daily timescale. The was conducted two contrasting years Guaraíra experimental basin, Brazil, 5.84‐km², tropical wet...
In-situ hydrological monitoring is essential for a proper decision-making process and modelling. Efforts have been made in Brazil to carry out field activities at the basin scale, but how complete comprehensive are those studies? Where they located? How long carried out? What main findings? To answer these questions, an overview of experimental basins presented, listing their geographical locations, monitored variables, operational status, periods publications. We identified 60 sites, spread...
Abstract This paper presents an improved method of using threshold peak rainfall intensity for robust flood/flash flood evaluation and warnings in the state São Paulo, Brazil. The improvements involve use two tolerance levels delineating intermediate by incorporating exponential curve that relates Antecedent Precipitation Index (API). application average increase 14% Probability Detection (POD) flash occurrences above upper threshold. Moreover, a considerable exclusion (63%) non-occurrences...
A variety of indicators antimicrobial use are available in veterinary medicine, their choice should depend on the study objective as none has been recognized most appropriate metric. Calculation is based a number parameters (e.g., treatment dose or weight at treatment) that can be informed using theoretical (also called "standard") actual "used") values. Although few studies compare application several to same data, obtained results lead apparent discrepancies contradictions. This aimed...
ABSTRACT The lack of process-based classification procedures may lead to unrealistic hyetograph design due complex oscillation rainfall depths when assimilated at high temporal resolutions. Four consecutive years sub-hourly data were in three study areas (Guaraíra, GEB, São João do Cariri, CEB, and Aiuaba, AEB) under distinct climates (very hot semi-arid tropical wet). This aimed define events (for Minimum Inter-event Time, MIT, Rainfall Depth, MRD, equal 30 min 1.016 mm, respectively),...
Os mapas de vulnerabilidade contaminação das águas subterrâneas, elaborados a partir Sistemas Informações Geográficas (SIG’s), vêm sendo cada vez mais utilizados para dar suporte aos planos gestão ambiental dos órgãos governamentais e não-governamentais. Este artigo mostra o mapeamento áreas vulneráveis à do aquífero livre da bacia hidrográfica rio Gramame (BRG). métodos DRASTIC modificado foram as ferramentas utilizadas nesta pesquisa. Esses calculam índice somatório parâmetros ambientais....
Abstract The study of rainfall properties at various spatiotemporal scales is deeply important for understanding a large range socio‐environmental processes and variables (e.g., water resources, agriculture, socio‐ecosystemic services, natural risk assessment). However, such studies on characteristics, especially sub‐hourly resolutions, are scarce in areas South America due to the lack high‐resolution temporal database.
