|Extended model description=SimClast is a basin-scale 3D stratigraphic model, which allows several interacting sedimentary environments. Processes included are; fluvial channel dynamics and overbank deposition, river plume deposition, open marine currents, wave resuspension, nearshore wave induced longshore and crosshore transport. This combined modelling approach allows insight into the processes influencing the flux of energy and clastic material and the effect of external perturbations in all environments. Many governing processes work on relatively small scales, e.g. in fluvial settings an avulsion is a relatively localised phenomenon. Yet, they have a profound effect on fluvial architecture. This means that the model must mimic these processes, but at the same time maintain computational efficiency. Additionally, long-term models use relatively large grid-sizing (km scale), as the area to be modelled is on the scale of continental margins. We solve this problem by implementing the governing processes as sub-grid scale routines into the large-scale basin-filling model. This parameterization greatly refines morphodynamic behaviour and the resulting stratigraphy. This modelling effort recreates realistic geomorphological and stratigraphic delta behaviour in river and wave-dominated settings. | |Extended model description=SimClast is a basin-scale 3D stratigraphic model, which allows several interacting sedimentary environments.

|Describe ideal data for testing=ClastSim is ideally used for field tests, a preferably well-studied area with some knowledge of the sediment budget is preferred. Most continental to shallow marine clastic coastal systems without too much tidal influence can be used. | |Describe ideal data for testing=ClastSim is ideally used for field tests, a preferably well-studied area with some knowledge of the sediment budget is preferred.
