# 集水节点

## 一般描述

这个 **集水节点** 是另一种具有固定流入量的输入节点。集水节点通常用于表示流入系统的河流或其他类型的流入。在它们上定义的任何流量都必须流入系统。

流入时间序列（例如 Pywr 数据框）通常定义在 *流* 属性表示集水流入量，但也可以使用其他参数（例如常量、月度概况等...）。

# 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/zhong-guo-ren/jian-mo-ji-chu-zhi-shi/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.
