Remote Sensing, 2023 Bed topography and roughness play important roles in numerous ice-sheet analyses. Although the coverage of ice-penetrating radar measurements has vastly increased over recent decades, significant data gaps remain in certain areas of subglacial topography

Grain and bedform roughness properties isolated from gravel-patch DEMs
E3S Web of Conferences, 2018 Remote sensing of gravel-bed patches and resulting high-resolution digital elevation models (DEMs) allow for the identification of various spatial scales of surface roughness.

Experimental investigation on bed shear stress distribution in the roughened compound channel
Applied Water Science, 2020 The roughness in the floodplains in a compound canal and its impact on hydraulic parameters such as the shear stress and their estimation are one of the problems that have attracted the attention of engineers.

Sand bed roughness in the nearshore [PDF]
Journal of Geophysical Research: Oceans, 2003 Measurements made using sonar altimeters mounted on an amphibious surveying vehicle are analyzed for root‐mean‐square (RMS) bedform roughness. Observations for 22 days over a 500 m × 700 m area are used to quantify the cross‐shore distribution of roughness and its variability. Large bedforms (with amplitudes 5–50 cm) occur frequently in shallow water (&

Discharge and location dependency of calibrated main channel roughness: Case study on the River Waal
E3S Web of Conferences, 2018 To accurately predict water levels, river models require an appropriate description of the hydraulic roughness. The bed roughness increases as river dunes grow with increasing discharge and the roughness depends on differences in channel width, bed level

Oscillatory Laminar Flow above a Rough Bed
Coastal Engineering 1978, 1978 Measurements are reported of the velocity distribution in the laminar boundary layer above a rough bed oscillating in its own plane in still air. The measurements were made with a hot-wire anemometer and the beds consisted of spheres packed closely together on flat plates.
