Hydrogeological Regions (HAD): Coastal Groundwater Influence in Germany

Hydrogeological regions data describes coastal groundwater bodies influenced by the North Sea and Baltic Sea. The dataset is provided by the Bundesamt für Kartographie und Geodäsie and is available via WMS service. It characterizes areas where usable groundwater is limited and often in contact with subterranean seawater.

Use Cases

• Model saltwater intrusion risk based on the described direct contact between groundwater-bearing rocks and subterranean seawater.
• Map usable groundwater resources based on the description of limited usable groundwater bodies, such as those on dune islands.
• Assess coastal aquifer vulnerability based on the described influence of the North Sea and Baltic Sea.

Strengths

• Data originates from the authoritative German national mapping agency, Bundesamt für Kartographie und Geodäsie.
• Description provides specific geographic context for coastal hydrogeology in Germany.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
