A landscape's sediment grain size distribution is the product of, and an important influence
on, earth surface processes and landscape evolution. Grains can be large enough that the …

Wildfire alters vegetation cover and soil hydrologic properties, substantially increasing the
likelihood of debris flows in steep watersheds. Our understanding of initiation mechanisms …

Biota are major drivers of geomorphological development. Vegetation and soil fauna act as
ecosystem engineers, changing the environment through physical structures and individual …

Debris flows are concentrated slurries of water and sediment that shape the landscape and
pose a major hazard to human life and infrastructure. Seismic ground motion‐based …

Landscapes following wildfire commonly have significant increases in sediment yield and
debris flows that pose major hazards and are difficult to predict. Ultimately, post-wildfire …

Slope‐stability models predict that steeper hillslopes require smaller hydrological triggers for
shallow landslides to occur due to the added downslope pull of gravity, which should result …

Post‐seismic debris flows are an important hazard following large earthquakes, propagating
destruction downstream from hillslopes where coseismic landslides occur and extending …

Sediment grain size links sediment production, weathering, and fining from fractured
bedrock on hillslopes to river incision and landscape relief. Yet models of sediment grain …

Wildfire can impact soil‐hydraulic properties by reducing saturated hydraulic conductivity
and sorptivity, making recently burned landscapes prone to debris flows and flash floods …

Although many steep landscapes comprise a patchwork of soil-mantled and bare-bedrock
hillslopes, models typically assume hillslopes are entirely soil-mantled or bare-bedrock …
