Summary: This study investigated sediment yield in two catchment areas within the Lena River catchment using the WaTEM/SEDEM model. The predicted sediment yield was found to be in better agreement with measured values in the Yakutsk catchment area compared to the Chara catchment area. Additionally, the study found that the predicted sediment yield remained relatively stable over the period 1986-2019, while the suspended sediment yield at the Tabaga gauging station showed a slight increase.

Summary: The study used radionuclide tracing to determine the relative contributions of stream bank and hillslope-derived sediment in three catchments in the upper North Island of New Zealand. Both lithogenic and fallout radionuclides were used to differentiate sediment sources, and a mixing model approach was utilized for prediction. The results showed that stream bank erosion can contribute significantly to sediment in New Zealand catchments.

Summary: Water bodies in Tanzania are facing increased siltation, driven by soil erosion and sediment transport. A lack of understanding about sources of sediment hinders effective mitigation efforts. By applying sediment tracing techniques, this study identified that hillslope erosion on rangelands and croplands is the main contributor to sediment load in Tanzanian rivers. This evidence links land use, erosion, and sediment transport, providing insights for targeted intervention.

Summary: Reliable quantitative information on sediment sources is crucial for river conservation and restoration. Sediment source fingerprinting is an independent field-based technique that identifies sediment sources in waterways. However, the lack of standardization limits its application in large-scale river basins.

Summary: This study investigates the use of carbon and nitrogen stable isotopic ratios in sediment fingerprinting studies. The results show that certain processes and considerations can significantly impact the isotopic ratios, while others have no significant effect. It is recommended to consider tracer conservativeness and concentration dependent mixing in fingerprinting simulations, as well as account for the loss of organic matter and algae accrual in sediment deposits. Both carbon and nitrogen isotopic ratios are suggested as potential tracers in future studies.

Summary: In this study, the results of sediment finger- printing research on riverbank erosion in 118 catchments across the globe were compiled and analyzed. The main objective was to assess different finger- printing tracers quantitatively and analyze the influence of catchment size on riverbank erosion. The findings showed that radionuclide tracers have the most consistent contributions to riverbank erosion, with riverbanks accounting for 1-25% of total sediment loss. However, there was a clear shift in contributions from surface sources to riverbanks with increasing catchment size. Therefore, long-term monitoring of sediment loads and riverbank erosion in nested catchments is recommended.

Summary: The purpose erosion and its spatial distribution in three agricultural headwater catchments were assessed in the border of the volcanic plateau in Southern Brazil. The results showed that areas covered by crop fields, grasslands, and those adjacent to the drainage network are the most sensitive to erosion. Unpaved roads were identified as significant sediment sources.

Summary: The source contributions to suspended and bed sediments in the polluted Ipojuca River system were quantified using geochemical tracers. The study identified the lower catchment, Oxisols, and sugarcane croplands as the dominant sediment sources. These findings are crucial for managing excessive sediment loads and sediment-associated contaminants in estuarine and coastal environments.

Summary: This study revealed the importance of disturbance extent and sediment pathways in controlling sediment transport in mining-disturbed areas. Sediment flushing mainly occurs in the most disturbed sub-catchments during the wet season, with hysteresis effects being significant. Floodplain sediment recycling plays a dominant role in sediment delivery at both reach and catchment scales, especially towards the end of the wet season.

Summary: Opencast mining in New Caledonia has worsened land degradation, with mining activities dominating sediment sources in the region. Geological tracers indicate that mining has significantly contributed to sediment deposition, while factors such as cyclones and collapses in mining areas have influenced sediment dynamics over time.

Summary: This study uses plutonium isotopes as tracers to investigate sediment transport in five watersheds in an urbanizing landscape in Kansas, USA. The results show that as the watersheds urbanize, the plutonium activity in transported sediment decreases, indicating a greater contribution from subsurface bank sediment. Pu239+240 activity provides additional information on sediment sources beyond that given by traditional tracers. This study demonstrates the utility of Pu239+240 as a sediment tracer for managing erosion under anthropogenic change.

Summary: The study presents an approach to evaluate soil erosion and sediment delivery models by incorporating sediment source fingerprinting and sediment-rating curve uncertainty. GLUE methodology applied to SEDD model revealed partial agreement between fingerprinting results and simulations, but high uncertainty in grid-based estimates of soil erosion and sediment delivery rates. Such errors should be considered standard practice in erosion models.

Summary: Successful river and floodplain restoration should aim to restore the river to its natural, quasi-equilibrium state prior to deliberate modification. The Natural Character Index (NCI) is proposed as a tool for assessing the extent and success of restoration efforts by comparing the current form and function of the river to historical data. Using parameters such as sinuosity, floodplain width, and riparian vegetation, the NCI offers a quantitative approach to evaluating restoration outcomes.

Summary: Silvopastoralism in New Zealand's hilly terrain is crucial for erosion and sediment control, but there has been little research on the effectiveness of tree planting in reducing landslide erosion. This study presents high-resolution tree influence models for dominant species, highlighting the significant contribution of exotic species such as poplars and willows to slope stability. Native vegetation like kanuka also plays a vital role in soil conservation, with potential for integration into landslide susceptibility modeling and targeted erosion mitigation plans.

Summary: Past research has emphasized the importance of sediment delivery from multiple-occurrence regional landslide events triggered by storms or earthquakes. This study focuses on a large, slow-moving landslide in the soft-rock hill country of Aotearoa New Zealand and reveals that the landslide continuously delivers sediment to the Rangitikei River, potentially impacting water quality.

Summary: Sediment fingerprinting is a useful technique for estimating the contribution of different sources to downstream environments. This study investigated the impact of tracer selection, number of sources, and dominant source on the accuracy of source apportionment. The results showed that increasing the number of sources decreased the accuracy, and the dominant source had the largest impact. The use of CSSI tracers in catchments with large differences in soil organic carbon content may introduce significant errors in source apportionments.

This study examined the influence of erosion sources defined by erosion process and geological parent material on sediment-related water quality attributes, particularly visual clarity. The findings highlight the need to consider both the quality and quantity of sediment when planning erosion control.

Summary: Contemporary management practices in Aotearoa New Zealand have constrained river systems to support land use, which undermines the functionality, biodiversity, and socio-cultural relations with rivers. The confinement of rivers can increase flood risk and limit adaptation to climate change. Despite aligning with Maori conceptualizations of rivers and Treaty of Waitangi obligations, space-to-move interventions have yet to be implemented.
