A model for fluvial bedrock incision by impacting suspended and bed load sediment [PDF]
, 2008 A mechanistic model is derived for the rate of fluvial erosion into bedrock by abrasion from uniform size particles that impact the bed during transport in both bed and suspended load.

Sampling Strategies to Improve Passive Optical Remote Sensing of River Bathymetry
Remote Sensing, 2018 Passive optical remote sensing of river bathymetry involves establishing a relation between depth and reflectance that can be applied throughout an image to produce a depth map. Building upon the Optimal Band Ratio Analysis (OBRA) framework, we introduce

Analytical model for flux saturation in sediment transport
, 2014 The transport of sediment by a fluid along the surface is responsible for dune formation, dust entrainment and for a rich diversity of patterns on the bottom of oceans, rivers, and planetary surfaces.
