  • The study is based on a 1D hydrodynamic model, which may not capture the full complexity of the flood dynamics. The structural analysis is preliminary and requires further validation. The study focuses on a specific location (Governador Valadares) and may not be directly applicable to other regions.

    MEDIDAS ESTRUTURAIS AUTOELEVÁVEIS NA MITIGAÇÃO DE RISCOS HIDROLÓGICOS: O CASO RIO DOCE (GOVERNADOR VALADARES/MG) · 2026 · DOI

  • Further validation of the structural analysis is required. The study suggests exploring the application of SCFBs in other regions with similar hydrological and topographical characteristics. Future research should focus on developing integrated approaches to flood mitigation, combining physical interventions with non-structural measures.
