This paper presents a new way of quantifying geometries of drainage networks, moving beyond river long profiles to explore the complexity of planform branching river networks. Using the proposed length asymmetry metric, the paper demonstrates that complexity is correlated with landscape aridity, where arid landscapes have less complex networks compared to humid ones, suggesting this metric could be a new way of exploring the impact of climate on Earth's topography.

Nghiem et al. calibrate and validate floc settling velocity models in freshwater, highlighting the controls on rates of sedimentation and organic carbon burial. The findings resolve discrepancies between observations and Stokes law-based models, which rely on floc characteristics like diameter, permeability, and fractal properties. This research advances our understanding of fine particle dynamics and their role in landscape evolution.

This research letter presents a conceptual model and data from physical experiments for a new mechanism of sediment entrainment on the seafloor during the huge co-seismic motion imposed by the large subduction earthquakes. This new mechanism introduces the concept of sediment entrainment being due to the motion of the sediment bed instead caused my movement of the water above. Furthermore, by identifying the sedimentary fingerprint of megathrust ruptures with high tsunamigenic potential, the authors propose a new approach to constraining the seismic and tsunami hazard in subduction zones.

This study provides sorely needed insights into the spatial and temporal variability in marram grass traits in relation to aeolian sand transport. This information will be highly relevant to developing and refining coastal dune formation models.

Understanding and modeling plastic transport in rivers is crucial because rivers act as major conduits for plastic waste from land to ocean. The study presents a model that provides insights into how plastics move through river systems. This work not only advances scientific understanding of pollutant dynamics but also supports environmental management, and helps protect aquatic ecosystems from the escalating threat of plastic pollution.
