- Abstract:
- 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 rivers start at a high point and move with a steep. River problems mainly appear after arriving in cities, which are located in planes. 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 for environmental remediation have been compiled and summarized, such as Riparian buffer , Wetland, Floating island (FI), River bank injection (RBI), Treatment block, etc. RBI and Riparian buffer impacts in river quality restoration through physical, chemical and biological actions are the most significant methods which can be pointed out. Actually, simultaneous use of Riparian buffer and RBI can decrease the pollution entering rivers. This method can be practicable from cost effective aspects in Iran and other countries Therefore, the purpose of this thesis is to provide a comprehensive overview of the techniques so as to select the best method for the Chalus River (with large buffer along the river and high precipitation)
