Exploring the contributions of vegetation and dune size to early dune development using unmanned aerial vehicle (UAV) imaging [PDF]

open access: yesBiogeosciences, 2017
Dune development along highly dynamic land–sea boundaries is the result of interaction between vegetation and dune size with sedimentation and erosion processes. Disentangling the contribution of vegetation characteristics from that of dune size would

The DUNE-ALUGrid Module

open access: yes, 2014
In this paper we present the new DUNE-ALUGrid module. This module contains a major overhaul of the sources from the ALUgrid library and the binding to the DUNE software framework. The main changes include user defined load balancing, parallel grid construction, and an redesign of the 2d grid which can now also be used for parallel computations.

Experimental Study of the Effect of Ripple Bedforms with Fine and Coarse Sediments on Bed Shear Stress

open access: yesعلوم آب و خاک, 2022
Bed shear stress is one of the most important hydraulic parameters to determine the amount of bed and suspended load and the bed and bank scouring in rivers. Bed shear stress depends on bedforms (ripples, dunes, and anti-dunes) in alluvial rivers.
