Microwatershed boundaries v1 and v2

The Microwatershed Boundaries v1 and Microwatershed Boundaries v2 datasets, part of the CoRE Stack, map fine-scale catchment areas derived from terrain-based hydrological modeling. Version 1 provides baseline microwatershed delineations for community-level water resource planning, while Version 2 offers an updated and more refined representation based on enhanced terrain and hydrological analysis. Together, they support precise and actionable planning for water resource management, watershed interventions, and ecosystem restoration.

About Dataset

The Microwatershed Boundaries v1 and Microwatershed Boundaries v2 datasets are fine-resolution hydrological boundary layers within the CoRE Stack (Commoning for Resilience and Equality), delineating small catchments nested within larger watersheds. Version 1 provides the initial mapping of local runoff convergence zones derived from terrain-based hydrological modeling, supporting participatory watershed planning, local water budgeting, and site-specific interventions such as check dams, recharge structures, and soil conservation measures. Version 2 offers an enhanced and more spatially accurate delineation through improved terrain preprocessing, flow modeling, and boundary correction techniques, enabling higher-resolution analysis for community-level water management and hydrological restoration. Both versions are harmonized with other CoRE Stack datasets—including Drainage Lines, Catchment Area, and Terrain—to support integrated watershed management workflows.

Purpose of Dataset

The Purpose Of The Microwatershed Boundaries V1 And V2 Datasets Is To Delineate Fine-scale Catchment Areas That Support Community-level Water Resource Planning And Watershed Management Within The Core Stack. Version 1 Enables Local Water Budgeting, Design Of Recharge And Conservation Structures, And Participatory Planning, While Version 2 Provides A More Accurate And Detailed Representation Through Improved Terrain And Hydrological Modeling For Higher-precision Microplanning And Restoration. Together, And When Integrated With Other Core Stack Layers, These Datasets Enable Site-specific, Data-driven, And Spatially Consistent Decision-making For Sustainable And Resilient Landscape Management.
