Análise da precipitação mensal provável para o município de Lages, SC

Abstract: RESUMOVisou-se, neste trabalho, determinar a precipitação pluviométrica mensal provável para Lages, SC. A análise consistiu do ajuste da distribuição de probabilidade teórica a uma série de dados de 80 anos de precipitação pluviométrica mensal. Em todos os meses a distribuição gama ajustou-se aos dados observados (p < 0,05). Para a estimação dos parâme-tros  e  da referida distribuição utilizaram-se o método da máxima verossimilhança e o teste de Kolmogorov-Smirnov, para verificar a aderência do modelo aos d… Show more

“…This did not occur in short-duration rainfall, which resulted in larger average intensities of the rains. There was a gradual decrease in rainfall average intensity expected values as duration of the rainfalls increased (Table 2), in according to data obtained from other researchers (Huff 1967;Souza Pinto et al 1973;Linsley and Franzini 1978;Righetto 1998;Soccol et al 2010). According to Silveira (2000), it was probably due to higher intensity values, which were related to rainfall events from connective processes that by observation, passed from a condition in short-term, even in temperate climates and, sometimes, during the winter.…”

“…Este atributo é usado também para o zoneamento climatológico de determinada cultura em uma região e, segundo Waldheim et al (2006), proporciona, ao agricultor, não só a escolha de culturas apropriadas mas também a aplicação de técnicas de manejo e de mitigação dos efeitos de eventos atmosféricos adversos. Soccol et al (2010) verificaram que a chuva média mensal provável para o município de Lages, SC, ocorreu a nível de probabilidade de 31,93%, com coeficiente de variação de 3,63%, revelando que o valor médio nem sempre pode ser tomado como referência em projetos agrícolas.…”

“…The estimated rainfall with certain level of probability is of great importance for agricultural planning, particularly in relation to irrigation management in a particular region and water suplly. Ribeiro et al (2007), Danfá et al (2010) and Soccol et al (2010) emphasizes that the use of occurrence probability values for monthly rainfall in irrigation projects decreases the system costs and can reduce awarded flows, facilitating the approval of these projects at environmental agencies. In each month and site, the probabilities were calculated from the best fit distribution parameters.…”

“…Agriculture has the rainfall as its main source of water, which may compromise the crop production due to its uneven behavior, sometimes with long periods of drought, sometimes with high intensity rains that exceed the water retention capacity of the soil, triggering floods SOCCOL et al, 2010;VIEIRA et al, 2010;CORRÊA et al, 2014). Besides the influence in agriculture, very long periods of droughts affect the water level of water sources and reservoirs of hydroelectric plants, bringing problems to the urban water supply and electric power generation (RODRIGUES et al, 2013;TEODORO et al, 2015a;TEODORO et al, 2016).…”
