Abstract. Earthquake-triggered landslides can be mapped using optical satellite images, but assessing how they evolve during earthquake sequences is difficult due to cloud cover in these data. This in...

Abstract. Landscapes evolve through the coupled effects of tectonics and surface processes. Previous studies have shown that uplift rate changes generate upstream-migrating erosion waves, altering dow...

Abstract. Many estuaries have mid-channel bars that emerge during low tide. In contrast to fringing tidal flats, these bars are fully surrounded by channels. This may lead to different hydrodynamics a...

Abstract. Bedload transport dynamics during rapid increases of stage remain poorly constrained, particularly in ephemeral streams where such conditions are common. We combined two cutting-edge monitor...

Abstract. Ribbed moraines are common landforms in regions formerly glaciated by the Fennoscandian, British and Laurentide ice sheets. Their process of formation is disputed, as formation conditions ar...

Abstract. The intersection of two non-parallel planes is a line. Howard (1990), following Horton (1932), proposed that the orientation and slope of a fluvial valley bottom within a tributary network a...

Abstract. Understanding the morphological responses of gravel-bed rivers to changes in external forces (e.g. water and sediment supply conditions) is a critical concern in river science and engineerin...

Abstract. Instream large wood (i.e. downed trees, branches, and roots larger than 1m in length and 10 cm in diameter) performs essential geomorphological and ecological functions that support the heal...

Abstract. Precise and reliable information about bedforms regarding geometry and dynamics is relevant for many applications – such as ensuring safe conditions for navigation along the waterways, param...
