Yangtze River basin ecological and hydrogeomorphic data relevant to regional hydrologic classification for sustainable dam operation

While some rivers have been modified and regulated for centuries requiring recovery efforts and restoration, other rivers are currently under development and facing the challenges of environmental degradation and loss of ecological functionality. As countries, such as China, expand current infrastructure to develop and construct flood reduction, hydropower, and water storage facilities along their rivers, the threat of detrimental ecological impacts expands too. To address these pressing challenges, this data set was used in the referenced article's analysis. Climatic, hydrogeomorphic, ecological, and anthropogenic characteristics summarized in this dataset were analyzed to determine the key principal components relevant to decision-making for environmental flows in the river basin. This resulting dataset includes a summary of the applied variables by subbasin cluster as discussed in detail in the article.
