Correntes de turbidez e implicações na sedimentação de reservatórios do semi-árido: proposta de arranjo experimental

Abstract

This paper aims to present and discuss the state of the art on turbidity currents and their implications on reservoir sedimentation, with emphasis on mathematical modeling, lab studies and field studies, and with particular attention to possible applications to the research on reservoir sedimentation in semi-arid areas. Around 60 scientific works are consulted, most of these being published in the two last decades, which shows a growing interest of the scientific community on the subject. Among these works, we select those that can be used as a reference for the development of experimental and theoretical studies on turbidity currents in semi-arid reservoirs, including processes that are not understood yet, such as delta redistribution and sediment flow through dam spillways. The results from these studies will help improve a semi-distributed model (Model of Water Availability in Semi-Arid Environments, WASA-SED) for evaluation of the impact of small dams in the hydrosedimentological balance in semi-arid basins
