For information about using Flood Modeller, we recommend browsing to the [How to](/v1/docs/how-to-introduction) section instead. ![TechnicalReferenceassetsimagesmainview.PNG](https://cdn.document360.io/5074bc26-a9ef-4bf4-b1de-a5c6ce628aca/Images/Documentation/TEChnicalReferenceassetsimagesmainview.PNG) The default layout of the Flood Modeller Graphical User Interface (GUI) is shown above. Each component of the GUI can be moved to a different location (Dockable Work Canvas) and even onto a different screen if you use several monitors (Multi Monitor Support). Please navigate this section via the contents on the left or the links below. #### Tabs The top toolbar ribbon is split into various categories for ease of use. The **Home** tab is always shown by default. Tabs at the top enable switching between the following: [Start tab](/v1/docs/start-tab) [Home tab](/v1/docs/home-tab) [1D river build tab](/v1/docs/1d-river-build-tab) [1D urban build tab](/v1/docs/1d-urban-build-tab) [2D build tab](/v1/docs/2d-build-tab) [Hydrology tab](/v1/docs/hydrology-tab) [Map tools tab](/v1/docs/map-tools-tab) [Simulation tab](/v1/docs/simulation-tab) [Results tab](/v1/docs/results-tab) The final tab is the [Layer editor tab](/v1/docs/layer-editor-tab), however this is not shown by default. In order to open this tab, you must right-click on a layer in the **Layers panel** and select **Start Edit** from the drop-down menu. --- #### Panels By default, the left-hand panel group consists of two panels as follows: [Project panel](/v1/docs/project-panel) [Layers panel](/v1/docs/layers-panel) The right-hand panel group contains the other available panels. Tabs at the bottom enable switching between the following: [River network panel](/v1/docs/river-network-panel) [River nodes panel](/v1/docs/river-node-panel) [Urban network panel](/v1/docs/urban-network-panel) [Toolbox panel](/v1/docs/toolbox-panel) [Timesteps panel](/v1/docs/timesteps-panel) [Error and diagnostics panel](/v1/docs/error-and-diagnostic-panel) --- #### Map view The centre of the interface displays the [Map view](/v1/docs/map) (by default).
