|CSDMS meeting abstract=Landslides are responsible for mobilizing enormous volumes of sediment from hillslopes into channels. At short timescales, these landslide deposits can change channel geometries and impact a system’s ability to efficiently export sediment. Mountain channels must mobilize this sediment before they can incise into their bedrock. There is evidence that mass failures like landsliding set an upper limit to relief and thus shape topography. However, few studies have investigated how landslides impact the landscape- and geologic-scale shape of landscapes. We aim to use topographic metrics to characterize how varying degrees of landsliding at geologic timescales shape landscapes. To address the long-term interplay between landslides, sediment dynamics, and the topographic evolution of Earth’s surface, we use landscape volution modeling which incorporates landslide triggering combined with river bedrock erosion, gravel transport that includes abrasion of both sediment load and bedrock, and dynamic channel adjustment consistent with that of near-threshold alluvial channels. We find that the inclusion of sediment attrition is necessary to reduce the flux of gravel and is consistent with inferences from field studies. We compare our model results to landscapes with constrained landslide histories among a spectrum of tectonic and climatic environments to assess our model’s ability to accurately capture realistic landscape features. This comparison enables us to explore the impact of future, rapid environmental climate change on landslide occurrence and risk, especially the influence of sediment supply on the cascade of downstream hazards<br />

|CSDMS meeting abstract title=The lasting legacy of megaflood boulder deposition in mountain rivers<br />

{{CSDMS meeting abstract template 2024<br />
|CSDMS meeting abstract=Infrequent, large-magnitude discharge (>10^6 m^3/s) outburst floods—megafloods—can play a major role in landscape evolution. Prehistoric glacial lake outburst megafloods transported and deposited large boulders (≥4 m), yet few studies consider their potential lasting impact on river processes and form. We use a numerical model, constrained by observed boulder size distributions, to investigate the fluvial response to boulder deposition by megaflooding in the Yarlung-Siang River, eastern Himalaya. Results show that boulder deposition changes local channel steepness (ksn) up to ∼180% compared to simulations without boulder bars, introducing >100 meter-scale knickpoints to the channel that can be sustained for >20 kyr. Simulations demonstrate that deposition of boulders in a single megaflood can have a greater influence on ksn than another common source of fluvial boulders: incision-rate-dependent delivery of boulders from hillslopes. Through widespread boulder deposition, megafloods leave a lasting legacy of channel disequilibrium that compounds over multiple floods and persists for millennia.<br />
