Coastal Erosion Study are to document the recent history of shoreline change in Hawaii and to determine the primary factor(s) responsible for coastal erosion in low-latitude environments.
Location
Oahu, HI
Summary
Biannual beach profiles
were collected at 42 Oahu and 36 Maui
locations between August 1994 and August 1999. Surveys were
conducted at approximately summer-winter intervals and extend
from landward of the active beach to about -4 meters water depth.
Profile data on a CDROM are presented in both Microsoft EXCEL
97/98 & 5.0/95 Workbook (.xls) format and comma separated value
(.csv) format. Graphical representation of the surveys (x vs. z and
x vs. y) are presented in EXCEL format only. Site descriptions,
including beach location, directions to site, GPS information,
and a description of Reference Points used, are available in both
EXCEL and ADOBE ACROBAT .pdf format.
Info derived
The overall goals of this study are to document the coastal erosion history in Hawaii, determine the causal factors of that erosion, provide high-quality data for other "end-users" in applied studies (i.e. coastal engineers, planners, and managers), and increase our general understanding of low-latitude coastal geologic development. This project involves close cooperation between the USGS Coastal and Marine Geology Program and the University of Hawaii.
The data and results are presented as a web site (a separate CDROM is also available). For the islands of Oahu and Maui, Index maps show the location of the beach profile monitoring sites. Each site is linked to a site map, photograph of the area, collection of beach profiles, and the profile data.
Comments
Other field activities at Ewa Beach Park on Oahu also have Activity IDs beginning with "E-W" and ending with "-OA"
Cross-shore beach profile data were collected as a component of the Hawaii Coastal Erosion Study, a cooperative effort by U.S.
Geological Survey and University of Hawaii in order to document
seasonal and longer-term variations in beach volume and behavior.
The overall objectives of the Hawaii Coastal Erosion Study are to
document the recent history of shoreline change in Hawaii and to
determine the primary factor(s) responsible for coastal erosion
in low-latitude environments for the purpose of predicting future
changes and to provide quality scientific data that is useful to
other scientists, planners, engineers, and coastal managers.
The overall strategy consists of first quantifying the magnitude
and location of serious erosion problems followed by close monitoring
of coastal change in critical areas. Bi-annual beach profiles have
been collected at over 40 critical beach sites on the islands of Oahu
and Maui. Once sufficient background information is analyzed and key
problems are defined, field sites will be selected for detailed process-
oriented studies (both physical and biological) to gain an understanding
of the complex relationships between reef carbonate production, sediment
dispersal, and the interaction of man-made structures with sediment
movement along the shore.
