What is hwlf?

HWLF (Hochwasserlinie fundierter Wasserstände) refers to the high water line based on substantiated water levels. It's a concept used in German hydrological and environmental contexts, particularly in flood risk management. It defines the line up to which water levels have demonstrably reached during past flood events.

The HWLF is more robust than a simple high water mark, as it requires documented evidence of the water levels reaching that point. This evidence may include historical records, photographs, eyewitness accounts, or scientific measurements.

The HWLF is often used in:

• Flood Risk Assessment: Determining areas susceptible to flooding and assessing the potential damage. More information about this can be found on Flood%20Risk%20Assessment page.
• Land Use Planning: Restricting development in areas prone to flooding, based on the established HWLF. See the definition of Land%20Use%20Planning for further details.
• Construction Regulations: Implementing building codes that require flood-proofing measures for structures located below the HWLF.
• Environmental Protection: Identifying and protecting wetlands and other areas important for flood control. Learn more about Environmental%20Protection.

Understanding and accurately determining the HWLF is crucial for effective flood management and mitigation strategies.
