The fundamental relationship between the concentration of suspended sediment, C, of a river and its water discharge, Q, during floods is studied qualitatively by analyzing temporal graphics and hysteresis curves (C-Q) graphics. The study of 20 floods of b... see more

Methods of monitoring suspended sediment concentration profiles have largely relied on in situ point sampling by water bottles, coupled with optical instrumentation. These intrusive methods can affect the measurements, and optical instrumentation must usu... see more

Backscatter output from a 10 MHz acoustic Doppler velocimeter (ADV) was used to quantify suspended sediment concentrations in a laboratory setting using sand-sized particles. The experiments included (a) well-sorted sand samples ranging in size from 0.112... see more

In the process of repair or restoration of building structures, it is often necessary to strengthen building structures from limestone-shell rock, concrete, reinforced concrete, hard materials-granite, basalt, etc. by cutting or making cuts of the require... see more

This work focuses on the distribution and the controlling factors of rare earth element (REE) total concentrations and fractionation patterns in fine sediment fractions of 53 samples collected along the main channels of the Ria de Aveiro, a northern Portu... see more

AbstractA survey of the water and sediment quality of the lower Olifants River and lower Selati River was carried out. Metal concentrations (Cr, Cu, Fe, Mn, Ni, Pb, Sr and Zn) in the water and sediment, as well as the physical and chemical characteristics... see more
