What do you mean by “hydrogeomorphic processes”? (Some thoughts following my GSA session on the topic.)

Geomorphologists increasingly recognize that the way water is delivered to and moves through a hillslope, river, or landscape affects surficial processes and geomorphic form. Hydrogeologists recognize that geomorphology drives the spatial and temporal distribution of shallow groundwater. But both groups … Continue reading

All quiet on the Alpine Fault?

The Alpine fault has not ruptured since European settlement in the 1840s. Paleoseismology tells us that this is the longest it has gone in a millenium without generating a magnitude 8+ earthquake. Continue reading

Anne’s picks of the literature: river and floodplain sediments

These four papers all attempt to understand what controls the sediments that make up the streambed and floodplain and that get preserved in the geologic record. White et al. look at how riffle positions are governed by valley width variations, while Jerolmack and Brzinski find striking similarities in grain size transitions observed in rivers and dune fields. Hart et al. examine the relationship between glacial advances and downstream sediment deposition, while Sambrook Smith et al. investigate the sedimentological record of floods. Continue reading

Anne’s picks of the June literature: Fluvial Geomorphology and Landscape Evolution

How do rivers erode bedrock streams, during big floods, and in the presence of groundwater? Laboratory and accidental experiments are providing some cool new insights. Continue reading
