Balanço Hídrico Climatológico: Precipitação E Evapotranspiração De Referência Estimadas Com Metodologia Alternativa

Abstract: Teve-se por objetivo analisar o desempenho de balanços hídricos diários calculados a partir das variáveis de entrada precipitação (P) e evapotranspiração de referência (ETo), estimadas de forma alternativa, em comparação com a metodologia padrão. Para tanto, foram obtidas medidas de P em um pluviômetro padrão do tipo Ville de Paris e em um pluviômetro alternativo constituído de garrafa PET. Para a estimativa da ETo foram empregados o método padrão de Penman-Monteith e o método alternativo de Camargo. Para fins… Show more

“…In order to avoid it, the study of rainfall (P) and reference evapotranspiration (ETo) are necessary, mainly in areas with poor rainfall distribution (Khanmohammadi et al, 2017). In addition to assisting in water resource planning and management in agricultural activities (Souza et al, 2017), they are the basis for calculating the agricultural water balance, allowing the assessment, and efficient and sustainable use of water, especially in irrigation management (Fernández-López et al, 2020).…”

“…However, as P and ETo are uncertain hydrological process, there are difficulties in planning agricultural activities, due to the lack of knowledge about their tendency over time and space. Although P is easily measured with rain gauges, ETo is a climatic variable that is difficult to measure using traditional methods, such as evapotranspirometers and lysimeters (Souza et al, 2017). Thus, the standardized Penman-Monteith approach parameterized by American Society of Civil Engineers is widely used to estimate ETo.…”
