Alternatively, if you select a node to add (see below) with no network loaded, Flood Modeller will assume you want to start a new network, and first prompt you for a network name and save location. Please note, this guide refers to the **River Section** node, however the same method applies for many other types of river nodes. Initially, confirm you are in **1D River** selection mode. Click on the **1D River Build** tab and select a node in your network. Your new node will be added downstream of the selected node (creating a new row below the selected node/row in the **1D River Network** panel). ![1DRiverimagesaddriversection.PNG](https://cdn.document360.io/5074bc26-a9ef-4bf4-b1de-a5c6ce628aca/Images/Documentation/1DRiverimagesaddriversection.PNG) Note: If your network contains no nodes, click the top row of your network in the **1D River Network** panel, named **General**. On the **1D River Build** tab, click on the **River Section** button so it is highlighted blue. Then on the map, click in the location you would like to place your **River Section**. A pop-up window will prompt you for a label for your node. You will need to ensure your **River Section** node label is not the same as another **River Section** node label in your network. For some nodes, connectivity is determined by the node label (e.g. a **Flow-Time** boundary node will have the same label as the **River Section** node it connects to). ![1DRiverimagesaddedriversection.PNG](https://cdn.document360.io/5074bc26-a9ef-4bf4-b1de-a5c6ce628aca/Images/Documentation/1DRiverimagesaddedriversection.PNG) Note: You can also add **River Section** nodes via the right-click menu from the **1D River Network** panel! Once you've added a new **River Section** node, recall we double-click to open and edit the properties. You can also [Move a River Section](/v1/docs/move-river-section) and [Delete a River Section](/v1/docs/delete-river-section) if needed. ## Related topics More about [River Section Nodes](/v1/docs/river-section-nodes)
