Nature based solutions as a promising alternative for river restoration and flood reduction

Abstract

Nature based solutions (NBS), have been used mainly in European countries, in the United States, and more recently in China. In this paper are identified international studies (2015-2018) which presented environmental solutions aiming at river requalification and reducing the effects of floods in municipalities. Based on the method of bibliographical revision, 12 (twelve) articles were selected. The results revealed that these nature based solutions of which uses tools from Natural Engineering and Biotechniques proved themselves to be efficient to promote the restoration of the hydromorphological conditions of the rivers, and its use in estuarine municipalities is suggested.
