Mean annual water-budget components for Hawaii Island, Hawaii, for recent conditions, 1916-83 rainfall and 2008 land cover

The shapefile associated with this metadata file represents the spatial distribution of mean annual 
water-budget components, in inches, for Hawaii Island, Hawaii. The water-budget components in 
the shapefile were computed by a water-budget model for a scenario representative of recent 
conditions (1916-83 rainfall and 2008 land cover), as described in USGS Scientific Investigations 
Report (SIR) 2011-5078 and summarized in USGS SIR 2015-5164. The model was developed for 
estimating groundwater recharge and other water-budget components for each subarea of the model. 
The model-subarea dataset, consisting of 467,805 subareas (polygons), was generated using Esri 
ArcGIS software by intersecting (merging) multiple spatial datasets. Spatial datasets merged 
includes those that characterize the spatial distribution of hydrologic and physical conditions 
(rainfall, fog interception, irrigation, reference evapotranspiration, direct runoff, soil type, and land 
cover) that the model uses to compute groundwater recharge and other water-budget components. 
Additional spatial datasets merged into the model-subarea dataset include those of select geographic 
features that assist in analyzing model results. This metadata file describes the process of merging 
these spatial datasets. The shapefile attribute information associated with each polygon present an 
estimate of mean annual rainfall, fog interception, irrigation, runoff, canopy evaporation, actual 
evapotranspiration, net precipitation, total evapotranspiration, recharge, and leakage from cesspools 
and water mains. This shapefile also includes select geographic and land-cover attributes of the 
polygons. Brief descriptions of the water-budget components and attributes are included in this 
metadata file. Refer to USGS SIR 2011-5078 and USGS SIR 2015-5164 for further details of the 
methods and sources used to determine these components and attributes.

KauaiE_shorelines - Shorelines of the eastern coastal region of Kauai, Hawaii, from Papaa to Nawiliwili, used in shoreline change analysis.

Sandy ocean beaches are a popular recreational destination, often surrounded by communities containing valuable real estate.  Development is on the rise despite the fact that coastal infrastructure is subjected to flooding and erosion.  As a result, there is an increased demand for accurate information regarding past and present shoreline changes.  To meet these national needs, the Coastal and Marine Geology Program of the U.S. Geological Survey (USGS) is compiling existing reliable historical shoreline data along open-ocean sandy shores of the conterminous United States and parts of Alaska and Hawaii under the National Assessment of Shoreline Change project.  Shoreline vectors derived from historic and modern sources represent the low water mark (beach toe).
There is no widely accepted standard for analyzing shoreline change.  Existing shoreline data measurements and rate calculation methods vary from study to study and prevent combining results into state-wide or regional assessments.  The impetus behind the National Assessment project was to develop a standardized method of measuring changes in shoreline position that is consistent from coast to coast.  The goal was to facilitate the process of periodically and systematically updating the results in an internally consistent manner.

Klamath Basin Restoration Agreement Off-Project Water Program Distance to Perennial Streams and Lakes

The Klamath Basin Restoration Agreement (KBRA) was developed by a diverse group of stakeholders, 
Federal and State resource management agencies, Tribal representatives, and interest groups to provide 
a comprehensive solution to ecological and water-supply issues in the Klamath Basin. The Off-Project 
Water Program (OPWP), one component of the KBRA, has as one of its purposes to permanently provide 
an additional 30,000 acre-feet of water per year on an average annual basis to Upper Klamath Lake through 
“voluntary retirement of water rights or water uses or other means as agreed to by the Klamath Tribes, to 
improve fisheries habitat and also provide for stability of irrigation water deliveries.” The geographic area 
where the water rights could be retired encompasses approximately 1,900 square miles. The OPWP area 
is defined as including the Sprague River drainage, the Sycan River drainage downstream of Sycan Marsh, 
the Wood River drainage, and the Williamson River drainage from Kirk Reef at the southern end of Klamath 
Marsh downstream to the confluence with the Sprague River. Extensive, broad, flat, poorly drained uplands, 
valleys, and wetlands characterize much of the study area. Irrigation is almost entirely used for pasture.
    To assist parties involved with decisionmaking and implementation of the OPWP, the U.S. Geological 
Survey (USGS), in cooperation with the Klamath Tribes and other stakeholders, created five hydrological 
information products. These products include GIS digital maps and datasets containing spatial information 
on evapotranspiration, subirrigation indicators, water rights, subbasin streamflow statistics, and return-flow 
indicators.

Umpqua River Oregon North Umpqua PhotoMosaic 1967

The Umpqua River drains 12,103 square kilometers (4,673 square miles) in southwest Oregon before flowing 
into the Pacific Ocean at Winchester Bay near the city of Reedsport. In cooperation with the Portland District 
of the U.S. Army Corps of Engineers (USACE), the USGS evaluated sediment transport and gravel storage 
along the downstream alluvial reaches of the North and South Umpqua Rivers and the entire mainstem 
Umpqua River. This includes the lower 46.8 kilometers (29.1 miles) of the North Umpqua River and the lower 
122.6 kilometers (76.2 miles) of the South Umpqua River. 
	 
The Umpqua River gravel transport study involved multiple analyses, including tracking patterns of historical 
channel change and estimation of a sediment budget. To support these analyses, digital channel maps were 
produced to depict channel and floodplain conditions along the Umpqua River system from different time periods.
		
GIS layers defining the active channel of the Umpqua River system were developed for three time periods: 
1939, 1967, and 2005. For the South Umpqua River and the 19 kilometers (12 miles) of the mainstem 
Umpqua River downstream from the confluence of the North and South Umpqua Rivers, GIS layers were 
also developed for the time periods 1994, 2000, and 2009.
		
For this project, the active channel was defined as area typically inundated during annual high flows, and 
includes the low-flow channel as well as side channels, islands, and channel-flanking gravel bars. The active 
channel datasets were developed by digitizing from aerial photographs. Aerial photographs from 1939 and 
1967 were scanned, rectified, and mosaiced for this project. Digital orthophotographs from 1994, 2000, 
2005, and 2009 are publicly available (See metadata for each photograph set for more information on the 
rectification process and resolution of each dataset). Although our study area encompasses the Umpqua 
River and lower reaches of the North and South Umpqua Rivers, the extent of each dataset depended upon 
the underlying aerial photographs; for example, the 1967 photographs extend only as far downstream as 
floodplain kilometer 7, whereas the 1939 and 2005 datasets extend to the mouth of the Umpqua River at 
the Pacific Ocean.

Sprague River Oregon Centerline North Fork 1968

The Sprague River drains 4090 square kilometers in south-central Oregon before flowing into the Williamson 
River and upper Klamath Lake. In cooperation with the U.S. Fish and Wildlife Service, the USGS and University 
of Oregon conducted a study to evaluate channel and floodplain processes for the 131 km of the Sprague River 
and its major tributaries, including the lower 20 km of the South Fork Sprague River, the lower 16 km of the North 
Fork Sprague River, and the lower 62 km of the Sycan River. The study involved multiple analyses, including 
assessments of historical channel change, riparian and floodplain vegetation, and surficial geology. To support 
these analyses, digital floodplain and channel maps were prepared from historic notes, maps, and aerial photos 
to depict channel and floodplain conditions at different times between 1866 and 2005. The geospatial database 
of current and historic channel and floodplain conditions will also enable evaluation of long-term trends pertaining 
to aquatic and riparian habitat conditions.

Salinity_GBI_tropical: Modeling the effects of large-scale interior headland restoration on tidal hydrodynamics and salinity transport in an open coast, marine-dominant estuary: model input and results

Using version 20.1_19 of the Discontinuous-Galerkin Shallow Water Equations Model (DG-SWEM) (Kubatko and others, 2006), astronomic tides and salinity transport were simulated at Grand Bay, Alabama (AL), under scenarios of interior headland restoration and sea level rise, as described in Passeri and others (2023). The two-dimensional DG-SWEM model can be applied to coastal and estuarine systems to solve for time-dependent hydrodynamic circulation and salinity transport. The DG-SWEM model uses the ADCIRC framework (Luettich and others, 1992) and requires inputs of an unstructured finite element mesh. For this study, the mesh domain has an open ocean boundary in the Gulf of Mexico and has higher spatial resolution elements (20 - 100 meters (m)) along the Mississippi and Alabama coast. The model mesh coordinates (latitude and longitude) and simulated average salinity concentrations are included in this data release. For further information regarding model input generation and visualization of model output, refer to Passeri and others (2023).

Global Multi-Resolution Terrain Elevation Data - National Geospatial Data Asset (NGDA)

The Global Multi-resolution Terrain Elevation Data 2010 (GMTED2010) provides a new level of detail in global topographic data. Previously, the best available global DEM was GTOPO30 with a horizontal grid spacing of 30 arc-seconds. The GMTED2010 product suite contains seven new raster elevation products for each of the 30-, 15-, and 7.5-arc-second spatial resolutions and incorporates the current best available global elevation data. The new elevation products have been produced using the following aggregation methods: minimum elevation, maximum elevation, mean elevation, median elevation, standard deviation of elevation, systematic subsample, and breakline emphasis. Metadata have also been produced to identify the source and attributes of all the input elevation data used to derive the output products. Many of these products will be suitable for various regional continental-scale land cover mapping, extraction of drainage features for hydrologic modeling, and geometric and radiometric correction of medium and coarse resolution satellite image data. The global aggregated vertical accuracy of GMTED2010 can be summarized in terms of the resolution and RMSE of the products with respect to a global set of control points (estimated global accuracy of 6 m RMSE) provided by the National Geospatial-Intelligence Agency (NGA). At 30 arc-seconds, the GMTED2010 RMSE range is between 25 and 42 meters; at 15 arc-seconds, the RMSE range is between 29 and 32 meters; and at 7.5 arc-seconds, the RMSE range is between 26 and 30 meters. GMTED2010 is a major improvement in consistency and vertical accuracy over GTOPO30, which has a 66 m RMSE globally compared to the same NGA control points. In areas where new sources of higher resolution data were available, the GMTED2010 products are substantially better than the aggregated global statistics; however, large areas still exist, particularly above 60 degrees North latitude, that lack good elevation data. As new data become available, especially in areas that have poor coverage in the current model, it is hoped that new versions of GMTED2010 might be generated and thus gradually improve the global model.
