Behaviour of Sediments in Water Structures

Abstract

Bottom sediments are a natural part of aquatic ecosystems. They are increasingly contributing to the deterioration of watercourses and reservoirs and are an undesirable material that causes various serious environmental and technical problems. The most significant problems include the instability of riverbeds, the transport of chemicals, nutrients and organic compounds, the supply of sediments to water reservoirs. Bottom sediments have the ability to bind to their surface various predominantly harmful substances such as heavy metals, radionuclides, nutrients and organic substances. Such sediments pose a risk to the water system in terms of possible remobilization of pollutants into the water.
