This digital collection results from a collaboration between these organizations in the University of Hawaii at Manoa:

The following people made this project happen:

  • WRRC faculty and HGGRC director Dr. Nicole Lautze led this project -- overseeing the digitization, metadata generation, and posting of these files.
  • Geology faculty member Dr. Scott Rowland picked up the print copies from the City.
  • Digitization Coordinator Alice Kim created the metadata.
  • Research assistants David Perreira and Honour Booth scanned the reports.
  • Library programmer Daniel Ishimitsu set up the collection onto ScholarSpace, the University’s digital repository, and will maintain it.

The National Science Foundation via the Ike Wai -- Epscor project (award #1557349) and UH Manoa Water Resources Research Center sponsored this digitization project.

Previously, the City’s Municipal Reference Center stored the hard copies of the reports in file cabinets. In 2017, the City decided to discard them and offered them to the University.
