Evaluation of reservoir-induced hydrological alterations and ecological flow based on mult

A study evaluates hydrological and ecological changes downstream of a reservoir using eco-flow indicators and 32 Indicators of Hydrologic Alteration. The analysis, conducted by Mingqian Li of Jilin University, reveals significant seasonal flow alterations and reduced ecological diversity post-reservoir construction. Results indicate high-flow values and frequency decreased, especially in autumn, while low-flow components increased significantly in spring and summer.

Use Cases

• Modeling seasonal hydrological alterations based on eco-flow indicators and flow duration curves.
• Assessing ecological diversity impacts based on changes in the Shannon Index.
• Analyzing reservoir regulation strategies based on correlations between eco-flow indicators and 32 IHAs.
• Evaluating the influence of precipitation on annual ecosurplus and ecodeficit metrics.

Strengths

• Analysis employs multiple hydrological indicators and eco-flow indicators for a multi-faceted evaluation.
• Study correlates eco-flow indicators with 32 Indicators of Hydrologic Alteration to avoid statistical redundancy.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
