# Nodo de captación

## Descripción general

El **nodo de captación** es otro tipo de nodo de entrada con un flujo de entrada fijo. Los nodos de captación se utilizan a menudo para representar ríos u otro tipo de afluencia al sistema. Cualquier flujo que se defina en ellos tiene que fluir al sistema.

A menudo, las series temporales de flujo de entrada (por ejemplo, los marcos de datos Pywr) se definen en el *flujo* atributo para representar las entradas de captación; sin embargo, también se pueden usar otros parámetros (por ejemplo, perfil constante, mensual, etc.).

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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/espanol/conceptos-basicos-de-modelado/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.
