# 对流域储层系统进行建模

在本教程中，您将学习如何向模型添加新的基础设施，包括水库、处理厂和可满足需求的地下水源。

请注意，WaterStrategy 和 Pywr 中有两个节点代表水库。第一个是 **存储** 节点，第二个是 **水库** 节点。

两个节点都储存水。水库节点的工作原理就像 storage node，但是它内置了允许你定义的参数 *蒸发* 和 *沉淀* 直接在节点上。为了代表 *蒸发* 和 *沉淀* 如果使用 storage node，则需要集水区和输出节点。

## 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/jiao-cheng/creating-a-reservoir-system.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.
