In the same way that watersheds filter pre … In the same way that watersheds filter precipitation signals into a time series of flow response, watersheds also filter sediment production signals into a time series of bedload transport. Here, we describe the Mass Wasting Router, a new watershed-scale sediment production and transport model written for Landlab that couples an existing shallow landslide hazard model (LandslideProbability) with an existing network-scale bedload transport model (NetworkSedimentTransporter) by (1) delineating hillslope scale landslides from maps of landslide probability, (2) routing the landslides through the watershed using a “precipiton” or “agent” style model and (3) fluvially eroding the mass wasting deposits and creating parcels for the NetworkSedimentTransporter. Preliminary model runs indicate that variation in soil cohesion and precipitation intensity drive landslide-derived hillslope sediment production rates but valley storage processes, driven by debris flow deposition patterns, modulate bedload transport rates at the basin outlet.dload transport rates at the basin outlet. +
