Silting is the accumulation of earth, garbage and organic matter at the bottom of a river. The phenomenon usually happens when the watercourse does not have riparian forests (vegetation on the banks of the river). Without the natural flora, wind and rain carry the surface layer of the soil towards the rivers, which results in environmental damage, such as the difficulty of navigating through the watercourse.
The phenomenon can happen naturally, but human actions have intensified the siltation process in Brazilian rivers. Deforestation is one of the biggest aggravating factors in this process. Without trees, shrubs or even grass, the soil is looser and less resistant, that is, more likely to be washed away by rain or wind. The lack of riparian forests also causes river slope erosion.
In addition to the difficulty of navigation, silting can cause other social and environmental damage. Due to sediments accumulated at the bottom of the bed, the water will look for shortcuts to follow its path. Often these diversions end up reaching areas with streets and houses, which causes urban floods.
When it loses depth with the accumulation of sediments, the width of the river grows and, due to the greater irradiation of the sun per area, the water temperature increases. The river's biodiversity feels the climate change. Underwater vegetation, fish and other animals are affected and may even disappear.
One of the solutions to avoid this phenomenon is the reforestation of areas close to the banks of water courses to prevent the entry of sediment into the rivers. Containing the erosive processes of riparian forests is another way to prevent and stop siltation.
