Method for Environmental Flows Regulation and Early Warning with Remote Sensing and Land Cover Data

Environmental flows play a vital role in ecosystem and water resource management. The regulation and management of environmental flows can improve the function and stability of river and lake ecosystems. However, current methods for assessing environmental flows mainly emphasize water management, an...

Notably, from 2005 to 2014 and in 2014, the available consumable water was less than the water consumption required for human activities, which both showed a trend of further reduction; therefore, long-term and annual early warnings should have been issued. The methods applied in this study and the study outcomes could help in the development of comprehensive management and ecological restoration plans, further improving the ecological environments of river basins.Yuming LuBingfang WuNana YanWeiwei ZhuHongwei ZengLinjiang WangMDPI AGarticleenvironmental flowsremote sensingland coverearly warningYongding River BasinAgricultureSENLand, Vol 10, Iss 1216, p 1216 (2021)
