Appropriate Methods of River Quality Restoration

The practice of river restoration has grown exponentially over the last several decades. There has been little empirical evaluation of whether restoration projects individually or cumulatively achieve the legally mandated goals of improving the structure and function of rivers. Nutrient reduction through simple methods is the most critical factor. The simplest method, which has minimal financial burden as well as preventing, and reducing the entrance of pollutants into the Chalus River (Mazandaran, in north of Iran), has been selected. The origins of most rivers in Iran start at a high point and move with a steep. Due to low speed and high pollution, rivers that arrive at cities or plain areas usually face problems. Due to this, compared with the rivers in other parts of world, the rivers in Iran carry more sediment, showing a high rate of erosion and inappropriate situation of natural resources such as deforestation and exploitation. As a result, a variety of techniques have been compiled and summarized, such as riparian, wetland, floating island, etc. Therefore, the purpose of this article is to provide a comprehensive overview of the techniques so as to select the best method for the Chalus River.
