Relação entre Chuva e Vazão

Visão geral

Este gráfico visualiza, ao longo do tempo, a relação entre intensidade de chuva e vazão do rio usando configuração de dois eixos. O eixo de chuva invertido (em cima) e o eixo de vazão (embaixo) criam uma leitura intuitiva: a chuva parece “cair” sobre a resposta de vazão abaixo.

Quando usar

Analisar relação chuva–escoamento (runoff)
Estudar resposta hidrológica a eventos de precipitação
Previsão e análise de enchentes
Gestão de recursos hídricos
Avaliações de impacto ambiental

Não é ideal

Quando você precisa de valores exatos de correlação (use análise estatística)
Comparar mais de duas variáveis relacionadas
Monitoramento em tempo real sem contexto histórico

Variações principais

Eixo secundário invertido para exibir chuva de forma intuitiva
Preenchimento de área para enfatizar magnitude das duas variáveis
Mark areas para destacar períodos/eventos específicos
Data zoom interativo para análise detalhada de intervalos
Escalas de tempo ajustáveis (horária, diária, semanal)

Casos de uso

Modelagem hidrológica e validação
Análise e previsão de eventos de cheia
Gestão de bacias hidrográficas
Operação de barragens e reservatórios
Estudos de impacto das mudanças climáticas

Dicas de desempenho

Amostre dados horários para intervalos de 3–6 horas em bases grandes
Use dataZoom para focar em períodos específicos
Ative dataZoom do tipo inside para pan/zoom mais fluido
Para tendências de longo prazo (meses/anos), agregue por dia
Em bases muito grandes, considere virtualização/scroll virtual

FAQ

Por que o eixo de chuva é invertido? Isso cria uma visualização mais intuitiva: a chuva parece “cair” de cima, deixando a relação de causa e efeito mais clara.

Como interpretar o atraso (lag) entre chuva e vazão? A diferença de tempo entre picos de chuva e picos de vazão indica o tempo de resposta da bacia, que depende de tamanho, declividade, solo e umidade antecedente.

O que as áreas destacadas representam? As mark areas destacam eventos ou períodos de interesse para análise focada.

Devo usar preenchimento de área para as duas séries? Sim. O preenchimento ajuda a enfatizar magnitude e torna os padrões mais visíveis.

Como lidar com dados ausentes? Prefira mostrar lacunas, sem interpolar. Dados ausentes podem indicar falha de equipamento ou problemas de qualidade que devem ser registrados.

Qual resolução temporal é melhor? Horária para análise detalhada de eventos; diária para padrões sazonais; semanal/mensal para tendências de longo prazo.

Como adicionar limiares de precipitação? Use markLines para indicar níveis de alerta de inundação ou outros limiares críticos no eixo de chuva.
