peilkaart

A peilkaart is a Dutch term that translates to "level map" or "depth map." It is a graphical representation of the water level or depth of a body of water, such as a river, canal, or lake. These maps are essential for navigation, hydraulic engineering, and water management.

Peilkaarten typically show contour lines representing different water depths. They may also indicate the location of important features like navigation channels, shallow areas, bridges, and locks. The data for a peilkaart is usually collected through hydrographic surveys, which involve using sonar or other instruments to measure the depth of the water at various points.

In the context of water management, peilkaarten can be used to monitor changes in water levels due to factors like rainfall, snowmelt, or tidal influences. They are also crucial for designing and maintaining infrastructure related to water, such as dams, dikes, and pumping stations. For navigators, a peilkaart provides vital information to ensure safe passage and avoid grounding.

The accuracy and detail of a peilkaart can vary depending on its purpose. Specialized peilkaarten might be created for specific industries or activities, such as fishing or recreational boating. The term "peilkaart" is specifically used in the Netherlands and Belgium, reflecting the importance of water management and navigation in these low-lying countries.
