Natural Depressions

The Natural Depressions dataset, part of the CoRE Stack, identifies terrain depressions and low-lying areas that act as natural water accumulation zones. It supports flood risk mapping, groundwater recharge analysis, and identification of potential water storage areas.

About Dataset

The Natural Depressions dataset is a CoRE Stack (Commoning for Resilience and Equality) geospatial layer representing low-lying terrain features identified through elevation and flow modeling. These depressions naturally capture surface runoff, forming ponds, wetlands, or temporary water storage zones. Understanding the distribution and size of natural depressions aids in watershed management, flood mitigation, and ecological restoration planning. When integrated with drainage, catchment, and land use layers, it enables holistic assessment of landscape hydrology and water balance.

Technical details and methodologies are available in the CoRE Stack Technical Manual: https://core-stack.org/core-stack-technical-manual-v2/

Purpose of Dataset

The Purpose Of The Natural Depressions Dataset Is To Identify Low-lying Terrain Areas That Naturally Store Surface Water, Supporting Flood Risk Assessment, Groundwater Recharge Analysis, And Water Resource Planning. It Helps Locate Potential Wetland Or Pond Formation Zones And, When Combined With Other Core Stack Hydrological Layers, Enables Integrated Watershed Management And Ecological Restoration Planning For Sustainable Landscape Development.
