Increasing water productivity has been viewed as an important strategy for reducing regional water scarcity in many countries, including China. However, some studies argue that improving water productivity may lead to a rebound effect that reversely aggravates water scarcity. This contradictory relationship is because that previous empirical assessments mostly focus on limited time spans, which raises

Dynamic risk evaluation of supersaturated dissolved gas at a confluence with unsteady flow conditions J. Hydrol. (IF 6.4) Pub Date : 2024-03-24 Zhuo Chen, Jingjie Feng, Ran Li, Qian Ma, Ruifeng Liang, Jingying Lu, Jingyang Xue
The confluence of two rivers gives rise to a distinctive hydrodynamic structure where numerous nutrients can be accumulated, making the confluence area a pivotal biological habitat. The threat of supersaturated dissolved gas in upstream water caused by dam discharging is indispensable for the confluence areas. Therefore, it is imperative to study and assess the risks faced by fish in these areas, particularly
