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
Maui, 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.
