Summary: Anthropogenic debris has widespread impacts on aquatic ecosystems, causing entanglement, ingestion, and bioaccumulation. The consequences of debris on individual organisms are known, but their impacts at management scales are poorly understood. This study provides a methodology to estimate specific debris items' risks to different organisms within a management area. Risk is determined by the consequence of interaction and the likelihood of exposure. The study identifies high-risk debris items and spatially assesses their variability, allowing for informed management decisions.

Summary: The author proposed a fractional approach to model cavitation erosion kinetics over two decades ago in response to issues in material resistance assessments from the International Cavitation Erosion Test project. The current status, potential, and limitations of the methodology were summarized in a paper published by Wear in 2020, along with details of the computational algorithm and examples illustrating the methodology description. Prospects for further development of the methodology are discussed in the paper.

Summary: Sand production in unconsolidated oil and gas reservoirs is a major challenge. Sand screens are commonly used to minimize production of sand, but they can also become ineffective when eroded. Predicting screen erosion is crucial for proper design, but finding a universal model for all flow conditions is challenging due to the complexity of erosion phenomena. This study presents, discusses, and analyzes existing prediction models, identifying areas for improvement and highlighting limitations.

Summary: Land use and landscape structure greatly affect flash floods in northern France's arable plateaus. Over the past few decades, landscape structures have changed, resulting in increased runoff and larger plots. This has led to increased connectivity from plots to thalwegs, increasing the risk of flash floods. This study uses a multiagent system to model this change in connectivity and develop indicators for spatial links in flow processes.

Summary: This paper presents a comparative study of sediment budgets for the largest Siberian rivers in Northern Eurasia. The data suggests that sediment sinks and storage in catchment and river networks dominate the sediment budget, leading to a significant decline in sediment transport compared to catchment erosion.

Summary: Large-scale dynamics of the brain can be modelled using nonlinear dynamical equations, with distinct neural populations coupled according to a measured structural connectivity matrix. Different choices in fMRI preprocessing can dramatically affect model fits and interpretations of findings. Our results suggest a need for tighter integration between data quality assurance and model development.

Summary: At the watershed scale, the relationship between soil erosion and sediment yield is complex and nonlinear due to temporal-spatial variations of rainfall and landscapes. While there has been widespread attention to soil erosion processes and sediment yield, systematic studies in this field are lacking. The study highlights the need to integrate connectivity and soil erosion models for a better understanding of erosion and sediment processes at the watershed scale.

Summary: This paper focuses on the back analysis of an ancient rock avalanche in Lettopalena, Italy. Various investigation methods were used, including manual surveys and remote sensing mapping for identifying geological structures. Numerical modeling and field investigations revealed that the landslide was controlled by translational sliding along a folded bedding plane, with toe removal due to river erosion. The results highlight the importance of combining geological models and numerical modeling to understand the development of rock avalanches.

Summary: Brazil is one of the largest consumers of pesticides in the world, leading to high contamination risks for the country's water bodies. The transport of pesticides is influenced by runoff and erosion processes, as well as hydrological dynamics. The study highlights the importance of monitoring major rainfall events in order to identify and quantify the occurrence of pesticides in the environment.

Summary: Soil erosion by water poses a serious threat to agricultural productivity and the environment, and climate change will worsen this problem. However, existing studies have limitations in applying climate scenarios to soil erosion models and considering the role of changing land use. This study addresses these gaps by developing a comprehensive method to select suitable climate models and examining the impact of different land use choices on soil erosion. The findings suggest that winter wheat is the most economically and environmentally viable land use choice to mitigate future soil erosion.

Summary: The El Nino event from September 2015 to February 2016 led to heavy rainfall in the state of Parana in southern Brazil. This study analyzed 32 precipitation series from 1981 to 2016 to map the magnitude of the event and its impact on the landscape. The six-month accumulated precipitation was found to be the most indicative parameter of extreme rainfall during the El Nino period. The results showed that a longitudinal strip of 450 km by 140 km experienced rainfall with a return period of over 30 years, reaching maximums exceeding 150 years. Field surveys and various sources confirmed the diverse impacts of the rainfall, including road blockages, water and power supply interruptions, and erosion in urban and rural areas. The study concluded that the regional geosystems' stability was disrupted by the extreme rainfall values, with the northwest region of Parana being less resilient compared to the north-central and Pioneer North regions due to differences in lithology and soil.
