Many of the younger flows (<1 Ma) have hummocky surfaces with abundant tumuli and lava rises, known locally as stony rises due to the protruding basalt boulders. Stony rises are noteworthy geologically but have ecological importance and are culturally significant to Aboriginal Australians. Ecologically, stony rises host many

Seismically induced hillslope disturbance, sediment connectivity and mass wasting: Insights from the 2008 Wenchuan earthquake Geomorphology (IF 3.9) Pub Date : 2024-01-16 Ming Chen, Chuan Tang, Ming Chang, Jiang Xiong
A mega-earthquake in a mountainous region can trigger thousands of landslides. Subsequently, these loose co-seismic materials will experience the erosion-transport-sediment process. This process is closely associated with a series of cascading hazards, such as landslides, debris flows and floods. The disturbance and legacy effects of earthquakes have become the focus of attention for post-earthquake

Assessing geomorphic and hydraulic changes related to an unplanned reconnection of the middle Mississippi River and its floodplain near Miller City, Illinois, USA Geomorphology (IF 3.9) Pub Date : 2024-01-15 Jonathan W.F. Remo, Tara L. Giri
The 2016 Len Small Levee breach and the decision not to repair this breach provides a unique opportunity to study the geomorphic and hydraulic changes associated with floodplain reconnection along a large (~30 km long) meander of the Mississippi River known as Dogtooth Bend. This study evaluates recent geomorphic, hydraulic, and sediment-transport capacity changes related to the breaching of the Len
