# 读取 CSV 数据框

前往 **新水库发布** 节点和更改 **最大流量** 到 **-400**，这将允许水流过这个节点

下载的文件， **泰晤士河\_李\_山谷\_demand.csv**，包含一个由两个关键列构成的时间序列数据集：

**时间步长：** 此列将用作时间序列的索引。它代表数据集中的时间进度，允许按时间顺序进行组织。

**李谷需求：** 此列包含代表李谷需求值的数据。

选择输出节点 **李谷需求** 然后编辑 **最大流量**

在 “选项” 中选择 **PYWR\_参数**

粘贴以下配置：

\`\`json { “类型”：“数据框参数”， “网址”：“泰晤士河\_李\_Valley\_demand.csv “， “专栏”：“李谷需求”， “index\_col”: “时间步”， “parse\_dates”：真 }

```

现在它应该如下图所示：

### 结果

点击节点 Lee Valley 需求 > 输出 > 模拟\ _flow 查看仿真结果

现在检查一下 **模拟\_卷** 为了 **新水库**
