“…One of the rare studies performed on a real river was published by Nazir et al (2016), who investigated sediment transport dynamic in a meandering uvial system of Chini River, Malaysia, with the aim to study the riverbed erosion and sedimentation processes. It was found that Chini River has sinuosity index of 1.98, what con rms instability of this river and that intense erosion processes are present on some parts of this river.…”

The aim of our study is to expand the world-wide knowledge about pollutant transport in sediments of medium-sized meandering rivers and to explain barium distribution in Kupa River (Croatia), as it showed as an ideal "natural laboratory".Sampling was performed twice at the same places with the time span of 15 years to see the changes in Ba concentrations after that period. Ba was analyzed using ICP-MS method on clay + silt sediment fraction (<63 µm). Modelling was performed in R environment (R version 3.5.1, 2018) and for solving the sediment transport equation of Ba in Kupa River a program based on nite differences is constructed.After barite mine ceased operation in 1990, Ba is still entering Kupica and Kupa rivers, as karstic underground still contains large amounts of barite waste. Ba concentrations in Kupa River sediments are still increasing consequently along the whole river length, except in Kupica River and rst downstream sample in Kupa River. It seems that in this part of river course erosion exceeded deposition processes. Also, there is an indication of changing the way of underground Ba transport. Erosion and deposition processes lead to formation of peak of Ba concentrations in the lower course of the Kupa River.Most important conclusion is that the mentioned peak was formed under one or two ood episodes, when sediment eroded from the upstream locations and was brought and deposited in the lower course of the river. Our modelling predicts that Ba source will not cease completely during the next 20 years.

Knowledge of sediment transport has been used to determine whether erosion or deposition will occur beneath the hydraulic structures, especially the magnitude of this erosion or deposition, and the time and distance over which it will occur. This paper, utilizes the stream gauging by wading method in estimating the bed load transport and scour depth in Kwadna Basin. The estimate of bed load transport enhances the understanding and design of the hydraulic structures overlying water bodies. The current meter was used in measuring stream flow velocity in three critical points along the Kwanda stream. The measurement was used to derive an equation for depth of scour and the rate of erosion after a period of time. Laboratory tests such as sieve analysis and specific gravity were carried out on the samples obtained from the field which showed that the sediment is poorly graded gravelly sand material. The results of the laboratory tests as well as the stream flow parameters of the stream were used to compute the expected volumetric total sediment load transported daily as 889.33 m 3 /day with annual value of 338347.158 m 3 /year. Kwadna stream bed material had a geometric mean particle size, D 50 , of 0.993 mm and consequently, the river transported bed material of larger diameter which explains why there are more deposits of sediments in the basin. The depth of scour for points 1, 2 and 3 after 365 days of high peak rainfall were estimated to be 1.0238, 1.7753 and 1.7019 m, respectively. The findings of this work will help in selecting suitable cross sections for the river structures having observed problems arising from sediment transport and deposition so as to reduce the sediments negative impacts on such structures.
