Lakeihin

Lakeihin is a term used in landscape engineering to denote the deliberate creation or enlargement of lakes within a watershed. It covers planning, design, and management approaches for improving water storage, flood mitigation, ecological value, and recreational opportunities. The concept emphasizes integrating lake creation with watershed hydrology, sediment management, and land-use planning. Proponents argue that lakeihin can enhance drought resilience, support biodiversity through connected wetlands, and provide urban amenities when implemented with careful design.

Practices commonly involved include damming or re-routing streams, excavating basins, and connecting new lakes to existing water bodies. In some deployments, multi-use systems combine surface water with groundwater recharge, while sediment control and water treatment measures aim to maintain water quality for ecological and human uses.

History and adoption of lakeihin has developed in regions facing increasing flood risk and water scarcity, particularly where urban development interfaces with agricultural landscapes. It is the subject of environmental planning guidelines and case studies comparing costs, ecological outcomes, and social impacts across projects.

Environmental and governance considerations include potential changes to flow regimes, sediment transport, and habitat connectivity. Successful implementation depends on environmental impact assessments, community engagement, and long-term maintenance planning. Critics point to ecological disruption, displacement, and high upfront costs.
