This dataset consists of a workspace (folder) containing 41 gridded datasets and a personal geodatabase. The gridded datasets consist of 28 precipitation-frequency grids, a mean annual precipitation grid, eight land cover grids, two soil permeability grids, a synthetic stream grid, and a region grid used in the Hawaii StreamStats application for peak flow estimates. The personal geodatabase contains a polygon feature class of exclusion polygons, which identify areas in which use the StreamStats application is restricted.

This dataset consists of a personal geodatabase containing several vector datasets. These datasets may be used with the ArcHydro Tools, developed by ESRI in partnership with the U.S. Geological Survey, StreamStats Development Team. The datasets, together with the ArcHydro Tools and the ArcHydro 8-digit HUC datasets for an area of interest, allow users to delineate watersheds and compute several watershed characteristics.

These datasets each consist of a workspace (folder) containing a collection of gridded datasets plus a personal geodatabase containing several vector datasets. These datasets are designed to be used with the ArcHydro Tools, developed by ESRI in partnership with the U.S. Geological Survey, StreamStats Development Team. The datasets, together with the ArcHydro Tools, allow users to delineate watersheds and compute several watershed characteristics. The datasets are distributed in folders named for the 8-digit Hydrologic Unit Code (HUC) each covers. The data structure is the same for each HUC. For Hawaii, the HUCs included correspond to the five largest islands.

This dataset consists of a workspace (folder) containing four gridded datasets and a personal geodatabase. The gridded datasets are a grid of mean annual precipitation, a grid of forest land cover, and region grids used in the Idaho StreamStats application. One region grid is for peak flow estimates, the other is for low flows, mean annual flows, and monthly flow statistics. The personal geodatabase contains a polygon feature class of exclusion polygons, which identify areas in which use the StreamStats application is restricted.

These datasets each consist of a folder containing a personal geodatabase of the NHD, and shapefiles used in the HydroDEM process. These files are provided as a means to document exactly which lines were used to develop the HydroDEMs. Each folder contains a line shapefile named for the 8-digit HUC code, containing the NHD flowlines that comprise the coastline for that island. The “hydrolines.shp” shapefile contains the lines that were burned into the DEM. These lines were selected from the NHD flowlines, with some minor editing in places. The “wbpolys.shp” shapefile contains the water-body polygons that were selected from the NHD and used in the bathymetric gradient process. The folders for HUCs 20010000 (Hawaii) and 20020000 (Maui) also contain a “walls.shp” shapefile, which contains the lines that were superimposed on the surface as “walls.”

This dataset consists of a personal geodatabase containing several vector datasets. This database contains the information needed to link the HUCs together so a watershed may be delineated that spans more than one 8-digit HUC.
