Generalized least-squares WREG regression files for Hawaiʻi flood-frequency analysis, based on data through water year 2020 The U.S. Geological Survey (USGS), in cooperation with the State of Hawaiʻi Department of Transportation, estimated flood magnitudes for the 50-, 20-, 10-, 4-, 2-, 1-, 0.5-, and 0.2-percent annual exceedance probabilities (AEP) for unregulated streamgages in Kauaʻi, Oʻahu, Molokaʻi, Maui, and Hawaiʻi, State of Hawaiʻi, using data through water year 2020. Regression equations which can be used to estimate flood magnitude and associated frequency at ungaged streams were developed. The methods and results of the study are published in a separate report (https://doi.org/10.3133/sir20235014). This data release contains (1) a folder with the PeakFQ output files for each streamgage, ".PRT" and ".EXP" files, for use in...

Kipuka Alala is recognized by the Army to be an important habitat that contains a number of unique plant communities as well as populations of several listed or rare plant species. Additionally, Kipuka Alala has been identified as a potential site for the reintroduction of the Palila (Loxioides bailleui), an endangered species of Hawaiian Honeycreeper bird that was...

Several layers were uset to create this version (v 3.4). The original HabQual layer was developed by Jon Price and Jim Jacobi based on the mapped land cover units from the Hawaii GAP analysis program (Gon et al. 2006). This map was revised by combining data on land use and the “Bare” category from the NOAA C-CAP 2005 map (NOAA National Ocean Service Coastal Services Center 2012), and adding road corridors to the heavily disturbed category based on the Tiger Roads layer (United States Census Bureau 2014). Additionally, corrections were made to this version of the map by visually inspecting previously mapped...

The basin characteristics, along with geospatial datasets for watershed delineation published as a separate USGS data release (https://doi.org/10.5066/P9N61WJ7), were used to delineate watersheds and determine basin characteristics in StreamStats for Hawaii.

Some of the more detailed and accurate maps include the Hawai‘i GAP Analysis (HI-GAP) Land Cover map (Gon et al. 2006), the NOAA C-CAP Land Cover map (NOAA National Ocean Service Coastal Services Center 2012), and the more recently released Hawai‘i LANDFIRE EVT Land Cover map (U.S. Geological Survey...

This map was orignally plotted on 1:24000-scale map sheets, using aerial photos taken in the years 1976-1977. Thus this map represents a snapshot of the vegetation at this time. The original mapping project was part of the the Hawaii Forest Bird Survey, and consequently only bird habitat areas of interest (495,454 ha or 47% of the island) were mapped. This dataset has the most detailed level of mapping, including information on canopy cover, canopy height, dominant tree species composition, species association type, dominant understory composition, and other information pertaining to the map unit.
