| One-line model description | Barrier Island Translation model |
| Extended model description | BIT Model aims to simulate the dynamics of the principal processes that govern the formation and evolution of a barrier island. The model includes sea-level oscillations and sediment distribution operated by waves and currents. Each process determines the deposition of a distinct sediment facies, separately schematized in the spatial domain. Therefore, at any temporal step, it is possible to recognize six different stratigraphic units: bedrock, transitional, overwash, shoreface aeolian and lagoonal. |

| Input - Output description | |
|---|---|
| Describe input parameters | Sea level curve; rate of lagoonal deposition; rate of overwash; initial shelf profile. The stratigraphic data are organized in a matrix of integers. Every matrix entry corresponds to a stratigraphic unit (bedrock, overwash, transitional, shoreface, aeolian and lagoonal). |
| Input format | ASCII, Binary |
| Other input format | |
| Describe output parameters | Resultant barrier island configuration and sediment distribution along the continental shelf as results of the effects of five different processes: reworking of the beach profile, inner-shelf sediment redistribution, overwash, laggonal deposition and aeolian sediment reworking. |

| Describe processes represented by the model | BIT Model takes into consideration five different processes:
|
| Describe key physical parameters and equations | The dynamics of erosion and deposition are schematized with a relationship, which represents a diffusion scheme that changes the bottom elevation at a rate linearly proportional to the difference between the current and the equilibrium profile, defined by the Dean's equation, and then redistributes the removed or deposited material in equal parts between the contiguous inshore and offshore locations. The phenomenon of overwash is schematized assuming that the first shoreface element of the barrier island is eroded of a quantity, which is related to the frequency of hurricanes and severe storms and to the difference between the maximum elevation of the barrier and the mean sea level. |

| Describe available test data sets | In order to verify the millennial-scale evolution of a barrier island, it is necessary to know the sea level curve, the rate of lagoonal deposition, the rate of overwash and the initial shelf profile. The BIT Model has been applied to the shelf profile in front of Sand Key, Florida. |

| Describe ideal data for testing | It would be interesting to have grainsize data in addition to the other data. |
