# Nodo de captação

## Descrição geral

O **nó de captação** é um outro tipo de nó de entrada com uma entrada fixa. Os nós de captação são frequentemente usados para representar o rio ou outro tipo de entrada no sistema. Qualquer fluxo definido neles deve fluir para o sistema.

Freqüentemente, séries temporais de entrada (por exemplo, quadros de dados Pywr) são definidas no *corrente* atributo para representar as entradas de captação, no entanto, outros parâmetros também podem ser usados (por exemplo, perfil constante, mensal, etc...).

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://water-strategy.gitbook.io/waterstrategy/portugues/nocoes-basicas-de-modelagem/node-types/water-input/catchment-node.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
