Multitemporal Analysis of Riverbank Areas in the Central Peruvian Andes

Riverbank areas are ecosystems dependent on watercourses or bodies of water with a variable matrix of vegetation, immersed in hydrographic basins. These zones fulfill essential functions for the preservation of ecosystems and their territorial relationships, which supply goods and services for biota and human well-being. On the other hand, riverbank erosion is an intrinsic and dynamic process of any alluvial river in which riverbanks become meandering and loosen on their developmental path to the mature stage. The dynamics of the riverside areas is highly complex, since different factors influence the decline of these areas, the most important factors are the increase in urbanization, the increase in agricultural areas, the intervention of livestock, among others. The state must play a primary role in the restoration and protection of the riparian areas, since there is a 2.58% decline in the riparian area in the province of Huancayo, given the importance of the ecosystem services that they provide to society. Therefore, specific standards for restoration of the edges of aquatic systems must be established, mainly in streams and rivers. Although there is a slight increase in the riverbank in one of the rivers of the Huancayo province due to climatic factors, this continues the same behavior in later years, so that in 35 years around 53.53 hectares of riverbank areas were lost, which indicates that in the next few years, you are completely devastated.
