Accommodation is the space made available for the accumulation of sediment that results from global sea level change and subsidence. In most cases, subsidence can be considered as constant.<ref name=ch21r33>Posamentier, H., W., Vail, P., R., 1988, Eustatic controls on clastic deposition II—sequence and systems tract models, in Wilgus, C., K., Hastings, B., S., Posamentier, H., W., Van Wagoner, J., Ross, C., A., Kendall, G., C., St., C., eds., Sea-Level Changes—An Integrated Approach: SEPM Special Publication 42, p. 125–154.</ref> Accommodation is equal to the rate of eustatic change minus the rate of subsidence. For example, if global sea level is falling at the same rate as subsidence, then no new space is made for sediment accumulation. However, if global sea level is falling but more slowly than the basin is subsiding, then new space is created.
