Describe processes represented by the model
Fluvial/alluvial processes;
Aggrading fluvial channels in one gridcell with crevasse. Subgrid sedimentation mimics alluvial ridge aggradation and overbank deposition. Avulsions are modelled one dimensionally by calculating the flow and sediment transport at prospective avulsion nodes. See also Dalman & Weltje (2008).
Floodplain processes;
Differential compaction, groundwater table, peat growth and overbank deposition
Hypopycnal plume and marine currents:
Rivers deliver sediment and water to the sea, where the river momentum spreads the suspended sediment in a plume. Multiple plumes and longshore current hydrodynamics are calculated using a potential flow routine. Subsequent sedimentation due to fallout uses the removal rate principle after Syvitski et al (1988).
Wave resuspension and crosshore transport;
Waves are modelled using linear Airy and Stokes wave theory. Deepwater wave height is derived from a Gaussian distribution to represent natural storm variability The asymmetric waves preferentially transport the sands (bedload fraction) shorewards and the fines (suspended load fraction) offshore. In combination with a littoral drift routine this allows waves to rework and transport sediments.
Describe key physical parameters and equations
tba
Describe length scale and resolution constraints
SimClast can theoretically be used on a length scale upwards of 20 kms, the upper limit is dependant on memory and processing restrictions. Typical length scales vary from 25 to 500 km. The highest resolution is mainly dependant on the use of intracellular fluvial deposition, as described in Dalman & Weltje (2008) this restricts the minimum cell size to 4 kms. Recent addition of floodplain process reduces this to 500 m.
Describe time scale and resolution constraints
Total time scale is merely dependant on computing time, typically on the order of several thousands to 100,000 years. Time steps are restricted to 1 year.
Describe any numerical limitations and issues
tba
Describe available calibration data sets

Describe available test data sets

Upload test data sets if available:
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.
Do you have current or future plans for collaborating with other researchers?
Current work in progress, will be updated when ready; Holocene development of the Rhine-Meuse delta (Utrecht University). Late Quaternary morphology and stratigraphy of the Northern Adriatic Basin. Large-scale stratigraphic patterns on the Vietnam shelf since the LGM (University of Kiel).
Is there a manual available?
