**NOLIFA** is a parameter in the fort.15 file controlling controlling the finite amplitude terms and wetting-drying in ADCIRC. The value of NOLIFA effects the meaning of the minimum water depth parameter (H0) and requires the specification of additional parameters together with H0.

## Parameter Summary

The following table is a summary of possible NOLIFA values, description, details, and other necessary or recommended input parameters.

NOLIFA Value | Description | Details | Required/Recommended Inputs |
---|---|---|---|

0 | No finite amplitude terms and no wetting-drying | The depth is linearized by using the bathymetric depth, rather than the total depth, in all terms except the transient term in the continuity equation. Wetting and drying of elements is disabled. Initial water depths are assumed equal to the bathymetric water depth specified in the fort.14 file. | H0, NOLICA = 0 |

1 | Finite amplitude terms without wetting-drying | Finite amplitude terms are included in the model run and wetting and drying of elements is disabled. Initial water depths are assumed equal to the bathymetric water depth specified in the fort.14 file. | H0, NOLICA = 1 |

2 | Finite amplitude terms with wetting-drying | Finite amplitude terms are included in the model run and wetting and drying of elements is enabled. Initial water depths are assumed equal to the bathymetric water depth specified in the fort.14 file. | H0, NOLICA = 1 |

## Usage Notes

When the finite amplitude terms are turned on, the time derivative portion of the advective terms should also be turned on for proper mass conservation and consistency (i.e., when NOLIFA > 0, then NOLICA = 1).
