System visualization (Water Overlay)

The printable version is no longer supported and may have rendering errors. Please update your browser bookmarks and please use the default browser print function instead.

When a Water Overlay is active, the water system and hydraulic constructions are schematically visualized to provide more insight. If water has flowed through any of the hydraulic constructions, animated arrows in the connecting lines will indicate that movement. Also, when zoomed in on the constructions, the Water level at either side of the construction is visible. Below an overview of the different components in the water system.

Water Objects

Type	Image	Description
Water area		Each Water area is visualized by a dashed border along the surface of the Terrain.
Breach		A Breach area is visualized by a purple sphere.
Weir		Schematic visualization of a Weir. The water levels at either side and also the direction of the flow is visible.
Culvert		Schematic visualization of a Culvert. The water levels at either side and also the direction of the flow is visible.
Pump		Schematic visualization of a Pump. The water levels at either side and also the direction of the flow is visible.
In- or Outlet		Schematic visualization of an Inlet or Outlet.
Sewer overflow		The Sewer overflow is visualized with a black sphere.
Sewer area		The Sewer area is visualized with an orange line which connects the center of the area with the Sewer overflow.

Water Areas

The following section is about the water system visualization. The initial setup is 0.4 m on the right and 0.3 m on the left.

Type	Overview	Description
Water area is connected and initially water is flowing out of it	.	Water area connected to another area and water is flowing out. Light blue color indicates that water level is within 0.1m of the initial water level. The number indicates the output datum height a or b of the water level
Water area not connected or initially no water flowing out of it		Water area connected to another area, but water is flowing out. The number indicates the output datum height a or b of the water level
Water area is connected and initially water is flowing out of it		Water area connected to another area and water is flowing out. Orange color indicates that the water level has lowered more than 0.1m compared to the initial water level. The number indicates the output datum height a or b of the water level.
Water area is not connected and initially water is flowing in to it. However, water is now flowing out.		Water area connected to another area and water is flowing back from an initial end point, indicated by the red line. Orange color indicates that the water level has lowered more than 0.1m compared to the initial water level. The number indicates the output datum height a or b of the water level.
Water area with an inlet connected to it.		Water area with an Inlet connected to it. Inlets are always orange.

Visualization options

In step 4 Interaction of the Water Overlay Wizard different options for visualizing the water system can be selected. Notice that multiple options at once can be selected.

Display Water Objects

This mode is by default selected and will schematically visualize the water system and hydraulic constructions as seen above.

Display Water Area System

This option adds a schematic visualization of water level areas, connected by hydraulic structures which is visible when zooming out. The directional flow between areas and the water level of areas will be visualized using color schemes, labels and shapes.

Display Weirs with Panels

Weir panel

When present, Weirs will be visualized with a Panel Popup. It is possible to click on this popup to open the Panel and change the Weir height. Note that a Test Run will start when changing this height. The panels are Template Excel panels which can be downloaded and adjusted as desired.

Display Water Areas with Panels

Water area panel

When present, Water areas will be highlighted with a Panel Popup. When clicking on this popup, the Panel opens and it is possible to change dynamically the Water level. Note that a Test Run will start when changing the Water level. The panels are Template Excel panels which can be downloaded and adjusted as desired.
