b. Structure Parameters. Data related to the inlet structures such as date built, structure
length, crown elevation and width, core elevation, side slope, and jetty offset for dual-jetty
systems.
c. Inlet Parameters. Includes parameters related to the inlet such as project width and depth,
tidal prism, throat cross-sectional area, bay surface area, ebb shoal volume, tide and
current gauge locations, and maximum average flood and ebb currents and direction.
A description of each database field is included on a separate web page linked to the database
web application. Many of the records are sparsely populated. This is typically due to lack of
information for that particular site, but another reason is whether the record is for an inlet or an
inlet structure. For example, a record for a natural inlet will not have any structure information,
so those fields will be vacant. For some inlets there are records associated with inlet jetties, but
no separate record for the inlet itself. In these cases the inlet parameters can be found in either
one or both of the records for the jetty structures.
ACCESSING THE DATABASE: The Inlets Database can be accessed from the Web site of
the Coastal Inlets Research Program (CIRP) located at the Uniform Resource Locator (URL)
under the menu item Database of Inlet Navigation Projects and Structures in the Featured Links
section on the right side of the page. Clicking on this link brings up an introduction to the
database in the browser window. Alternately, the database can be accessed directly at the URL
The database introduction page contains two links.
The link Access the Database brings up the interactive database application as shown in
Figure 1.
The link Explanation of Database Fields brings up the Web page describing the database
fields and the three-letter codes assigned for the various coasts.
STANDARD DATABASE QUERIES: There are two simple point and click methods for
selecting a subset of records from the database.
a. Rapid selection. Clicking on one of the letters given in the "Rapid Selection" section as
shown on Figure 1 will list all the records beginning with that letter. The records are
sorted in alphabetical order. For example, to locate the record for Barnegat Inlet, click on
the letter B.
