Property:Describe time scale and resolution
From CSDMS
This is a property of type Text.
C
1 year time steps, good results up to 200-300 years +
D
1. Sediment transport time through a catchment
2. Exhumation time from a depth of a thermochronometric closure isotherm to the surface +

A parameter called the CFL number controls the time step in relation to the spatial scales. For boussinesq simulations, a CFL number of 0.2 is usually sufficient for code stability. However, for the non-boussinesq simulations, I usually have to lower the CFL number to around 0.05. It's really just a bit of trial and error though. +

C
Averaging time is on the order of annual averages so that individual storm events are not represented. Problems usually are scaled for years, to decades all the way up to millenia. +
P
CFL condition +
S
R
Code has been most commonly run at 1 year time steps for up to 6000 years. Time steps are constrained by rates of evolution of topography due to episodic sediment transport events and peat accretion and how quickly those processes affect the flow field. In the situation for which the model was developed, sediment accumulates at a mean rate of 1 mm/yr. +
G
Constraints:
* Time step - 1 - 50 years
* Duration - Hundreds to thousands of years +
Currently does not time-evolve. I would like to couple this to a 3D viscoelastic mantle at some point, but this hasn't happened yet. +
