Soil Subsidence Sensitivity in South Holland at 1.0 Meter Dewatering Depth

South Holland's soil subsidence sensitivity map, calculated for a fixed dewatering depth of 1.0 meters over a 100-year theoretical period. The dataset, provided by the Dutch Ministry of the Interior and Kingdom Relations, classifies land into three categories based on subsurface structure: 'not relevant', 'relevant', and 'special focus area'. It highlights areas with thick peat layers, such as parts of Midden-Delfland and Alblasserwaard, as requiring special attention for design and water management.

Use Cases

• Assessing land suitability for construction based on soil subsidence sensitivity classes.
• Modeling long-term hydrological impacts on peat and clay areas based on theoretical oxidation and riveting.
• Prioritizing areas for water management interventions based on the 'special focus area' classification.
• Comparing subsidence scenarios for different dewatering depths (0.5m, 1.0m, 1.5m) mentioned in the description.

Strengths

• Provides a clear three-class sensitivity system ('not relevant', 'relevant', 'special focus area') for risk assessment.
• Based on a defined theoretical model over a 100-year period with a fixed dewatering depth of 1.0 meters.
• Identifies specific geographic areas of concern, such as the Alblasserwaard and Krimpenerwaard.

Limitations

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