COHERENS  hydrodynamic 
COHERENS is a modelling system designed for a wide range of applications in coastal and shelf seas, estuaries, lakes and reservoirs. COHERENS follows a modular structure based on a numerical hydrodynamical model. It includes sidemodules among which generic biological and sediment transport modules. 
WAM  spectral wave model 
WAMC4 is a thirdgeneration wave model, which solves the wave transport equation explicitly without any a priori assumptions on the shape of the wave energy spectrum. https://github.com/mywave/WAM 
sediment transport 
Finite Elements for NavierStokes, Sediment Transport & Turbulence The model solves the full hydrodynamic equations for the velocity components and the pressure, and the sediment transport equation (or sediment mass balance) for the sediment concentration.

Open source Field Operation And Manipulation OpenFOAM® is an open source library of applications and solvers for simulating computational continuum mechanics (CCM) (Weller et al., 1998). Solvers for the simulation of computational fluid dynamics (CFD) form a significant branch in the OpenFOAM® library. It includes the solver interFoam, a NavierStokes (NS) equations solver following an Eulerian meshbased method for two incompressible, isothermal immiscible fluids. The interface between water and air (the two fluids of interest here) and its advection is obtained by the VolumeofFluid (VOF) phasefraction based interface capturing approach described by Berberović et al. (2009). 

SedFOAM  sediment transport 
SedFOAM is a solver in OpenFOAM to solve sediment transport using Eulerian twophase flow theory. https://github.com/SedFoam/sedfoam 
MixtSedFOAM  sediment transport 
MixtSedFOAM is a solver in OpenFOAM to solve sediment transport using advanced mixture flow theory. Ouda M., Toorman E.A. (2019). Development of a new multiphase sediment transport model for free surface flows. International Journal of Multiphase Flow, 117(8): 81102. https://doi.org/10.1016/j.ijmultiphaseflow.2019.04.023 
hydrodynamic wave 
C++ and CUDA code (Dual), based on Smoothed Particle Hydrodynamics method DualSPHysics is based on the Smoothed Particle Hydrodynamics model named SPHysics (www.sphysics.org). The code is developed to study freesurface flow phenomena where Eulerian methods can be difficult to apply, such as waves or impact of dambreaks on offshore structures. DualSPHysics is a set of C++, CUDA and Java codes designed to deal with reallife engineering problems. 

sediment transport morphodynamic 
SISYPHE can be used to model complex morphodynamics processes in diverse environments, such as coastal, rivers, lakes and estuaries, for different flow rates, sediment size classes and sediment transport modes. http://www.opentelemac.org/index.php/moduleslist/164sysiphesedimenttransportandbedevolution 

spectral wave model 
Simulating Waves Nearshore SWAN is a thirdgeneration wave model, developed at Delft University of Technology, that computes random, shortcrested windgenerated waves in coastal regions and inland waters. For more information about SWAN, see a short overview of model features. This list reflects on the scientific relevance of the development of SWAN. http://swanmodel.sourceforge.net/ 

waveresolving wave model 
Simulating WAves till Shore SWASH is a generalpurpose numerical tool for simulating unsteady, nonhydrostatic, freesurface, rotational flow and transport phenomena in coastal waters as driven by waves, tides, buoyancy and wind forces. It provides a general basis for describing wave transformations from deep water to a beach, port or harbour, complex changes to rapidly varied flows, and density driven flows in coastal seas, estuaries, lakes and rivers. http://swash.sourceforge.net/ 

hydrodynamic 
TELEMAC2D is used to simulate freesurface flows in two dimensions of horizontal space. At each point of the mesh, the program calculates the depth of water and the two velocity components. TELEMAC3D is a threedimensional (3D) model that uses the same horizontally unstructured mesh as TELEMAC2D. The model was written primarily to solve the shallow water equations in 3D format but an option is also available to solve the governing equations including dynamic pressure so allowing shorter waves than those in a shallow water context. 

spectral wave model 
TELEMACbased Operational Model Addressing Wave Action Computation TOMAWAC is used to model wave propagation in coastal areas. By means of a finiteelement type method, it solves a simplified equation for the spectroangular density of wave action. This is done for steadystate conditions (i.e. with a fixed depth of water throughout the simulation). http://www.opentelemac.org/index.php/moduleslist/20tomawac 

morphodynamics 
Xbeach (Roelvink et al., 2009) is a processbased 2D morphodynamic model solving the shallow water equations for the flow. It focuses on nearshore processes and aims at predicting beach and coastline evolutions during storms. For this reason the modelling of wave effects and other crossshore transport mechanisms are expected to be very detailed. The software is still in development, the manual is not uptodate but the code is open source and can hence be adapted to the needs. Morphodynamic computation is long but parallel computing is possible. https://oss.deltares.nl/web/xbeach/ 

UNIBEST CL+  coastline morphodynamic 
The program UNIBESTCL+ is a powerful tool to model longshore sediment transports and morphodynamics of coastlines. Shoreline migration is computed on the basis of computed longshore transports at specific locations along the coast. If required the effect of crossshore phenomena can be assessed with the UNIBESTTC and UNIBESTDE modules. The UNIBESTCL+ model runs are very timeefficient, which allows for the evaluation of multiple scenarios as well as sensitivity analyses. The shoreline model UNIBESTCL+ can be used for a wide range of coastal engineering projects. A typical application is the analysis of the large scale morphology of coastal systems to provide insight into the causes of coastal erosion or to predict the impact of planned coastal infrastructure (such as a port) on the coast. Shoreline evolution computations can be made over a period of decades, but also for considerations on a smaller time and spatial scale. It is possible to evaluate the shoreline evolution around coastal protection works (groynes, revetments, river mouth training works and to some extent detached breakwaters). https://www.deltares.nl/en/software/unibestcl/
