EcoFlow was founded in May 2017 by Bruce Wang. [4] They started with the launch of the RIVER mobile power station. [5] By 2019, the company expanded to Tokyo, Japan and introduced the DELTA 1300 with faster charging. [6] The following year, in 2020, the RIVER series followed, offering smart energy management features.
River engineering also handles sediment and erosion control, which can be a threat to humankind by destroying infrastructure, hindering water supply and causing major river cutoffs. River training structures will help to modify the hydraulic flow and the sediment response of a river. [5] Miyagase Dam in Japan
The National River Linking Project (NRLP) is designed to ease water shortages in western and southern India while mitigating the impacts of recurrent floods in the eastern parts of the Ganga basin. The NRLP, if and when implemented, will be one of the biggest interbasin water transfer projects in the world. [2]
[2] Beginning in the late 20th century, the river engineering discipline has been more focused on repairing hydromodified degradations and accounting for potential systematic response to planned alterations by considering fluvial geomorphology. Fluvial geomorphology is the study of how rivers change their form over time.
Topsoil runoff from farm, central Iowa (2011). Water pollution in the United States is a growing problem that became critical in the 19th century with the development of mechanized agriculture, mining, and manufacturing industries—although laws and regulations introduced in the late 20th century have improved water quality in many water bodies.

This stream operating together with its environment can be thought of as forming a river ecosystem. River ecosystems are flowing waters that drain the landscape, and include the biotic (living) interactions amongst plants, animals and micro-organisms, as well as abiotic (nonliving) physical and chemical interactions of its many parts.
The international scale of river difficulty is an American system used to rate the difficulty of navigating a stretch of river, or a single (sometimes whitewater) rapid. [1] The scale was created by the American Whitewater Association to evaluate rivers throughout the world, hence international in the title. [ 2 ]
