Environmental and Social Impacts of Río Piedras Dam: Stakeholder Considerations and Flow Predictions

This study explores the environmental and social implications of the Río Piedras Dam, focusing on watershed processes, stakeholder involvement, and water management. Key factors include precipitation, land use, and socio-economic impacts, particularly for local communities, ranchers, and farmers. The research encompasses predictive modeling for ungauged river flows while also considering regulatory frameworks under Costa Rica's national water policy and comparative laws, including NEPA in the United States. The findings aim to guide sustainable water use and dam management practices.
