Critical shear stress for erosion of sand and mud mixtures
TL;DR: In this paper, the critical shear stress for erosion of sand and mud mixtures is theoretically investigated and expressed as a function of the critical stresses of pure sand and sand, mud content, and sand diameter.

A Non-Equilibrium Sediment Transport Model for Coastal Inlets and Navigation Channels
Alejandro Sanchez,Weiming Wu +1 more
TL;DR: In this article, a depth-averaged sediment transport model with emphasis on morphodynamic processes near coastal inlets and navigation channels is presented, considering bed material hiding and exposure, avalanching and sediment transport over hard bottoms.

The Coastal Modeling System Flow Model (CMS-Flow): Past and Present
TL;DR: CMS-Flow as discussed by the authors is a coupled time-dependent circulation, sediment transport and morphodynamic model based on the numerical solution of the mass, momentum and transport equations on a Cartesian (quad-tree) grid network with both explicit and implicit solvers.

An Implicit 2-D Shallow Water Flow Model on Unstructured Quadtree Rectangular Mesh
TL;DR: In this article, an implicit finite volume scheme is developed to solve the depth-averaged 2-D shallow water flow equations, where the computational mesh consists of rectangular cells, with quadtree technology incorporated to locally refine the mesh around structures of interest or where the topography and/or flow properties change sharply.

TL;DR: In this paper, three one-dimensional (1D) numerical wave models are evaluated for wave transformation over reefs and estimates of wave setup, runup, and ponding levels in an island setting where the beach is fronted by fringing reef and lagoons.
