A new analytical model describes how the amount and grain size of sediment transported by rivers influences bedrock channel width, which can be used to predict where rivers will widen or narrow.
Registros individuales de paleohuracanes extraídos de los sedimentos de islas azotadas por tormentas no muestran una clara influencia del clima en la frecuencia de los huracanes en el último milenio.
Laboratory experiments and grain-scale computer simulations during the past decade have led to a more universal understanding of flow-driven sediment transport across flows in oil, water, and air.
Signals in layers of sedimentary rock hint at climates and ecosystems come and gone. Understanding this history can help us forecast the future, but challenges abound.
Terrestrial meander migration rates are used to estimate a formation timescale of decades for Jezero delta on Mars.
High nutrient concentrations cause water quality problems in lakes, and as the climate warms, these issues will only get worse. A new model assesses future scenarios and explores solutions.
New research suggests that an accurate prediction of colloidal particle mobilization in the environment should account for the effect of clustering.
A new long-term flume experiment shows that bed load gravel travels downstream in recurring, 10-hour pulses even when water flow and sediment supply are constant.
For the first time, researchers combine estimates of sea surface height and circulation patterns in both ice-covered and ice-free regions of the Southern Ocean.
A new modeling blueprint seeks to unify sedimentology, hydrology, and hydrogeology in the modeling of streambeds.
