Sediment dynamics in cascade reservoir systems as a basis for contributions to water resources management. A review

Sediment dynamics in cascade reservoirs is an important topic for understanding impacts on reservoirs. Several studies have been carried out to evaluate different aspects of sediments, such as the dynamics of substances, microbial activity and the functioning of cascade reservoirs for hydrological optimization. To evaluate the behavior of sediments in cascade reservoir systems, a systematic literature review was carried out using the keywords “sediments in cascade reservoirs” and “cascade reservoir modeling” in ScienceDirect and CAPES Journals. The review identified conceptual differences regarding what constitutes a reservoir cascade. Furthermore, groups of studies were identified that address sedimentary dynamics in cascade reservoir systems using different methods, including variables that influence sedimentological processes, reservoir operation, field sampling, reservoir influence analysis and hydrosedimentological modeling. These studies are relevant for understanding sediment dynamics in cascade reservoir systems and can be useful for planning and managing these systems.
