Title:
kauai_ero - Erosion Hazard Intensity Level in the coastal zone of Kauai, Hawaii
Abstract:
Erosion Hazard Intensity Level in the coastal zone of Kauai, Hawaii
Supplemental_Information:
Data included here were derived from the technical hazard maps published in the 'Atlas of Natural Hazards in the Hawaiian Coastal Zone' (Fletcher etal. 2002) The atlas reports on a program of research that assigns a relative ranking scale to seven natural coastal hazards. The ranking is based on the historical trends and natural factors influencing site vulnerability and hazard intensity in the Hawaiian coastal zone. Information contained within the Atlas is largely based on previous investigations by scientific and engineering researchers and county, state, and federal offices and agencies. The unique aspect of this report is that, to the extent possible, it assimilates prior efforts in documenting Hawaiian coastal hazards and combines existing knowledge into a single comprehensive coastal hazard data set. It is by no means the final word on coastal hazards in Hawaii. Every hazardous phenomenon described, and others such as slope failure and rocky shoreline collapse, need to be more carefully quantified, forecast, and mitigated. The technical hazard maps were constructed for the entire shorelines of the islands of Kauai, Oahu, Molokai, Lanai, Maui, and Hawaii at a scale of 1:50,000 (1 inch on the map equals approximately 0.8 miles). The technical map series displays the nominal relative intensity (on a ranked scale of 1 to 4, where 4 is most intense; overall hazard assessment is on a ranked scale of 1 to 7, where 7 is most intense) of each of the seven hazards following a set of specific definitions.

  2. How were the data generated, processed, and modified?
    Date: 2002 (process 1 of 5)
    The original data used to create this shapefile was converted to an ARCVIEW polyline shapefile from an ARC/INFO .e00 coverage of the Hawaiin islands distributed by the State of Hawaii via the web. The line file was subset into seperate lines for each island,and the topology was then "cleaned up" using an ESRI sample script. The line was then dynamically segmented according to the exisiting coastal hazard atlas. Person who carried out this activity:
