View to the south from the roof of the Tiara Condominium.
This ABMS is located on the roof of the 46-story Tiara Condominium on Singer Island, Palm Beach County, north of the Lake Worth Inlet.  The cameras are looking south at approximately 3 km of beach, monitoring the shoreline changes and nearshore processes both north and south of this northern inlet to Lake Worth near Palm Beach (site map).

There are four cameras; two are for mapping the beach north of the northern breakwater and two are for mapping the beach south of the southern breakwater.  The system was installed at the end of August, 2001. Nearly two years of images have been acquired; image acquisition was completed in late July, 2003. All images are available in the image archive.

The latest images from the four cameras are available below.  Image time stamps are in Eastern Standard Time (EST) year round.  Click on an image to enlarge it.  All images are archived and may be viewed or downloaded by visiting the image archive.

The ABMS monitoring is in support of the Palm Beach Harbor/Lake Worth Inlet sand bypassing project. Video monitoring is sponsored by the USACE District, Jacksonville, and Palm Beach County. Technical support is provided by the US Army Engineer Research and Development Center's (ERDC) Coastal Hydraulics Laboratory (CHL) and Field Research Facility (FRF) and Northwest Research Associates.

ABMS data supports the following investigative objectives:

  1. Quantify the spatial and temporal evolution of shoreline change on beaches directly influenced by a sand transfer plant operating at the inlet
  2. Identify the spatial and temporal characteristics of a littoral sediment transport nodal point that occurs on the beach immediately down-drift (south) of the inlet
  3. Provide a validation data set to augment an existing shoreline change numerical modeling investigation.

Oblique ARGUS image data are rectified into a coordinate system of choice to quanitfy the location and evolution of the nearshore features of interest. Rectified images for 02 October 2001 are shown below. Click on an image to enlarge it.
