Sediment classification in a Brazilian reservoir: Pros and cons of parametric low frequencies
Advances in Oceanography and Limnology, 2019 Sediment is the main factor that limits the reservoir lifetime. Therefore, sediment classification is an essential tool for planning and operating reservoir management measures. There has been important development in the hydroacoustic classification of

Seabed Sediment Classification using Multifrequency Backscatter
IOP Conference Series: Earth and Environmental Science, 2023 Abstract Seabed sediment serves as an important metric for assessing marine ecosystems. Different sectors, including the development and utilization of marine resources, marine engineering, environmental research, marine fisheries, and maritime navigation safety, all depend on the classification and identification of different forms of ...
