The data sets presented in the Federal Inlets Database were developed from sources
within nineteen Corps of Engineers Districts, from university and consulting industry
reports, and from individuals conducting research at various tidal inlets throughout the
study region. Values presented in the database are representative. Many of the
parameters reported, such as tidal prism, are not constant and vary over different time
scales and in response to engineering activities such as dredging and dredge and fill.
Therefore, the year of measurement is noted in the database. In many cases, however,
only one value was reported without a corresponding date because of limited data
available for the particular inlet. These values must be taken as estimates for the inlets
and considered with caution.
Work is ongoing to populate the database and validate numbers, historical and recent,
that it contains. Primary sources of the information are also being linked as metadata and
for reference to other, associated information.
The intent of this effort is to gather the necessary data to enable coastal engineers and
scientists to more fully understand the physical processes occurring at those inlets of
economic and environmental interest to the U.S. Army Corps of Engineers. The focus of
this specific work is to expand the database to include all inlets, Federal and non-Federal,
within the United States and its territories. Work is underway to include non-Federal
inlets, with that database containing more than 500 entries at present.
In addition to being a scientific resource, it is anticipated that the database will be
consulted to develop reliable and cost-effective engineering solutions.
The authors would like to thank Steve Hughes, Mark Byrnes, Julie Rosati, and the
personnel from numerous U.S. Army Corps of Engineers Districts and others who
provided information on Federal and non-Federal inlets and entrances for this study. This
study is a product of the Inlet Geomorphology and Channels Work Unit of the Coastal
Inlets Research Program. Permission was granted by Headquarters, U.S. Army Corps of
Engineers to publish this information.
