Summing the various tributary contributions of the Rhone River produces a sediment budget that is close to the sediment export at the river mouth.
Another objective concerned the source identification of the Rhone sediments with regard to the major tributary contributions, and to test whether the sediment fluxes are in equilibrium in the basin.
In the tributaries, annual contributions of M2 vary from 37% to as high as 65%.
The estimated contribution of the tributary surface waters to the spring flow during the research period was approximately 26 53% (Fuensanta river) and 47 74% (Convento stream), being predominant the first component during high flow and the second one during the dry season.
Rivers arise from the contributions of smaller tributary streams.
In conclusion, natural phosphate removal in the Abukuma River can be attributed primarily to high ratios of aluminum oxide minerals transported by volcanic tributaries, suggesting a significant hydrological contribution of volcanic catchments to in-stream phosphate transport.
Crystal Springs Creek and Kelley Creek are the largest tributaries in terms of flow contribution.
Rigorous statistical methods were used to define end-members, evaluate mineralogical variability, assess similarities among samples, and eventually calculate the relative contributions from each major tributary to the trunk river by forward end-member modelling of integrated compositional data.
In this section, we examine whether it is possible to distinguish the provenance of the fine-silt fraction of sediments at the rivermouth using ESR signal intensity and CI values, especially the relative contributions of sediments from two tributary groups within the Yangtze drainage basin: the western plus northeastern tributaries and the southeastern tributaries, as shown in Fig. 9.
Following the river from its sources, an estimate can be made of the contribution of the various lakes and tributaries in the Nile flood.
The analyzed ESR signal intensities agree well with the predicted values (within the reproducibility of the analyzed ESR values; ±2.2) below the junctions with the Minjiang, Jialingjiang, and Poyang Lake tributaries, indicating that the analyzed ESR signal intensity properly reflects the relative sediment contributions from the mainstream and the tributary from above the junctions.
