Hydrologic changes and human interventions gradually change the river course. Geomorphology or study of rivers’ behavior seeks to determine the action and the reaction or the behavior of rivers in various conditions. The propensity of rivers to geomorphologic changes, over time, has been clear and ascertained since almost a century. It is very much important to protect and train rivers, coastal regions and to protect lands and valuable reserves on riversides (pumping stations, treatment plants, water-supply wells, prawn-rearing basins etc.). Taking into account vegetation and its use in protecting and training riversides will lessen unnecessary costs and prevent environmental effects and geomorphologic changes of rivers over time. This article is dedicated to investigate advantages and disadvantages of protecting and training of riversides by vegetation against geomorphologic changes.
