Property:Describe time scale and resolution
From CSDMS
This is a property of type Text.
B
Timesteps in the range of 1-10 years are generally stable, can run for as long as desired until the memory runs out. +
C
Topographic analysis so no time scale constraints. +
S
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. +
E
B
Typical time scale of order tens to hundreds of thousands of years. +
I
T
Typical timesteps are on the order of seconds to minutes. Model can be run for a full year or longer, if necessary. +

D
Typically millions of years to tens of millions of year +
M
F
Wave-current BL: timescale ~10 min; time step ~0.01 sec; Tidal BL: timescale days and time step 10 s +
E
We present an equilibrium solution that may or may not be reached. The fundamental assumption is that in the absence of subsidence, uplift and change of downstream water surface base level, an alluvial river will evolve toward an equilibrium state in which overbank and bar deposition (floodplain construction) are perfectly balanced by the removal of floodplain sediment due to channel migration (floodplain shaving) (Lauer & Parker, 2006). This equilibrium state can be reached if hydrologic regime, sediment supply and caliber do not vary in time.

Q
We use the ‘basin equilibrium timescale’ (Paola 2000), defined as the length scale square divided by the fluvial diffusivity. In field settings, this time scale can range from centennial to millennia up to millions of years. +
M
Yearly time steps are appropriate +
C

C
Years to millenia. Typically, the model is run with timesteps on the order of a day. However, the assumptions that the shoreface progrades or erodes while maintaining its cross-shore shape prevents model results from being interpreted as meaningful over time scales shorter than years to decades. (Storm and post storm cross-shore shifting of sediment within the shoreface causes shoreline fluctuations on event timescales that are implicitly averaged out in this model.) +
