Exploring equifinality in a landscape evolution model
… are established from published data and calibration. Parameter space sampling is then carried out using a response surface methodology approach which reduces by c. 3 orders of magnitude the simulation run size needed to explore the 10-D parameter space. Initial simulations are run sampling the …

Why Are Some Watersheds More Sediment-Productive Than Others? An Explainable AI Approach
The Sediment Delivery Ratio (SDR) represents the proportion of eroded sediment within a watershed that ultimately reaches its outlet. Sediment yield (SY) is defined as the amount of sediment exported from a watershed outlet per unit time, normalized by drainage area. Quantifying the spatial …

Geomorphic and Fluvial Response to Recent Permafrost Disturbances in a High Arctic River, Cape Bounty, Nunavut
Using a sediment budget approach, suspended sediment transport dynamics were studied over the 2010 summer runoff season in the 8 km2 West River catchment at the Cape Bounty Arctic Watershed Observatory (CBAWO), Melville Island, Nunavut. Research was carried out in an effort to determine the longer …

Geospatial analysis of specific degradation in South Korea
… Korea experienced many local and concentrated sediment problems such as landslides, upland erosion, rills and valleys, aggradation/degradation, and flood plain sediment deposition. These problems vary in space and time, therefore a reliable and consistent approach to model sediment processes is …

Analysis of sediment dynamics in intensively managed landscapes
The flux of fine sediment within agricultural watersheds is an important factor determining the environmental quality of streams and rivers. Human activity has significantly altered the hydrological and biogeochemical cycles within terrestrial and aquatic environments through agricultural …
