    Description

    A crosswalk table between NHDPlus version 2.1 flowlines (using the unique field COMID) and the Watershed Boundary Dataset (WBD) 12-digit-hydrologic units (HU-12) is provided for the 48 contiguous United States. The crosswalk table provides a WBD HU-12 assignment for every networked flowline in the NHDPlus. In this way, the network developed for navigation and modeling, NHDPlus, is aligned with accounting units of the WBD HU-12s to the extent possible given the assumptions that were made in creating each. A crosswalk table for NHDPlus isolated sinks was produced by a simple overlay process where the sinks were assigned HU-12 values based on their position relative to the WBD snapshot HU-12s. This table was integrated with the flowline associations into one crosswalk table for both feature types. There is good alignment between aggregated NHDPlus catchments and WBD HU-12 units in many locations. These are areas where the flows and chemical or nutrient loads that are accumulated leav ...

    Description

    The comid field of these data can be used to join to the National Hydrography Dataset Plus V2.1 (NHDPlusV2) flowline comid or catchment featureid attributes. The included attributes follow the same data model as the NHDPlusV2 but include numerous updates and improvements to network connectivity. All attributes that depend on network connectivity have been recalculated. These attributes are based on the NHDPlusV2 network geometry and modifications retrieved from the National Water Model V2.1 (NWMv2.1) and "E2NHDPlusV2_us: Database of Ancillary Hydrologic Attributes and Modified Routing for NHDPlus Version 2.1 Flowlines" (E2NHDPlusV2) datasets. The attributes included are: comid, tocomid, fcode, nameID, lengthkm, reachcode, frommeas, tomeas, arbolate_sum, terminalpa ,hydroseq, levelpathi, pathlength, dnhydroseq, areasqkm, totdasqkm, terminalfl, dnlevelpat. These attributes are available in three formats: csv, fst, and parquet. "fst" is a high-performance format for use with the R programming language "fst" package. "parquet" is a high-performance format for use with multiple programming languages (including python) that support the Apache Arrow Parquet format.

    Description

    This tabular data set represents the presence of six National Hydrography Dataset (NHD) high resolution waterbody types compiled for two spatial components of the NHDPlus version 2 data suite (NHDPlusv2) for the conterminous United States; 1) individual reach catchments and 2) reach catchments accumulated upstream through the river network. The six types of waterbodies presented here are: playa, ice mass, lake/pond, reservoir, swamp/marsh, and estuary. This dataset can be linked to the NHDPlus version 2 data suite by the unique identifier COMID. The source data is the NHDPlus high resolution waterbodies produced by USGS , 2015. Units are percent. Reach catchment information characterizes data at the local scale. Reach catchments accumulated upstream through the river network characterizes cumulative upstream conditions. Network-accumulated values are computed using two methods, 1) divergence-routed and 2) total cumulative drainage area. Both approaches use a modified routing data ...

    Description

    These attributes are based on the NHDPlusV2 network geometry and modifications retrieved from the National Water Model V2.1 (NWMv2.1) and "E2NHDPlusV2_us: Database of Ancillary Hydrologic Attributes and Modified Routing for NHDPlus Version 2.1 Flowlines" (E2NHDPlusV2) datasets. The attributes included are: comid, tocomid, ftype, fcode, gnis_name, gnis_id, fromnode, tonode, divergence, streamleve, streamorde, streamcalc, reachcode, frommeas, tomeas, lengthkm, arbolatesu, pathlength, areasqkm, totdasqkm, hwnodesqkm, hydroseq, dnhydroseq, levelpathi, terminalpa, dnlevelpat, terminalfl, terminalfl, wbareatype, wbareacomi, slope, slopelenkm, roughness, vpuin, vpuout, rpuid, vpuid. These attributes are available in four formats: csv, fst, parquet, and geopackage. "fst" is a high-performance format for use with the R programming language "fst" package. "parquet" is a high-performance format for use with multiple programming languages (including python) that support the Apache Arrow Parquet format. Geopackage is an open standard geodatabase format and includes both the attributes and geometry included in this data release. The comid field of these data can be used to join to the National Hydrography Dataset Plus V2.1 (NHDPlusV2) flowline comid or catchment featureid attributes. The included attributes follow the same data model as the NHDPlusV2 but include numerous updates and improvements to network connectivity. All attributes that depend on network connectivity have been recalculated. Version 3.0 includes updated flowline geometry in a geopackage geodatabase file with node geometry digitized in agreement with the network topology and all derived attributes compatible with non-dendritic network assumptions. Version 3.0 also now includes specific records of edits applied to the NHDPlusV2 from the NWMV2.1 and E2NHDPlusV2 in seperate geopackage geodatabases. See the entity and attributes section of this metadata record for more information.

    Description

    This metadata record describes a series of data sets of natural and anthropogenic landscape features linked to NHDPlus Version 2.1’s (NHDPlusV2) approximately 2.7 million stream segments, their associated catchments, and their upstream watersheds within the conterminous United States. The data were linked to four spatial components of NHDPlusV2: individual reach catchments, riparian buffer zones around individual reaches, reach catchments accumulated downstream through the river network, and riparian buffer zones accumulated downstream through the river network. All data can be linked to NHDPlus using the COMID field in these tables and the ComID in the flowline shapefiles or FEATUREID in the catchment ones in the NHDPlus data suite. The datasets were derived using a topologically reconditioned version of the NHDPlusv2 routing network (Schwarz and Wieczorek, 2018). This database is used for the routing of upstream watersheds only. No cartographic changes were made to the original NHDPlusv2 in either the flowline or reach catchment line work. These data are listed under 13 themes which include: 1) Best Management Practices, characteristics such as agricultural management practices and land in conservation practices. 2) Chemical, characteristics such as nitrogen application or toxicity weighted use. 3) Climate and Water Balance Model, characteristics such as model outputs of runoff, actual evapotranspiration or ground water storage. 4) Climate, characteristics such as mean precipitation, temperature, relative humidity, or evapotranspiration. 5) Geology, characteristics such as Hunt or Soller surficial geologies. 6) Hydrologic, characteristics such as base flow or infiltration excess overland flow.Hydrologic Modifications, characteristics such as dam storage or tile drains. 7) Hydrologic Modifications, characteristics such as dam storage or tile drains. 8) Landscape, characteristics such as NLCD, CDL or NWALT. 9) Population Infrastructure, characteristics such as population, housing, and road densities. 10) Regions, characteristics such as EcoRegions, Physiography or Hydrologic Landscapes. 11) Soils, characteristics such as STATSGO, soil salinity, and soil restrictive layer. 12) Topographic Characteristics, characteristics such as basin area, slope and elevation. 13) Water use, characteristics such as estimated freshwater withdrawls and estimated freshwater consumption by thermo-electric power plants These data allow researchers and managers to acquire landscape information for both catchments (for example, the nearby landscape flowing directly into streams) and full upstream watersheds of specific stream reaches anywhere in the within the conterminous United States without having to perform specialized geospatial processing. Aside from comma separated text files, parquet files with the same file structure were also added to each data file under each child item theme. This format will allow researchers to acquire all the information from this data release in an efficient and consistent manner by utilizing and thereby adhering to the FAIR guidelines outlined in Lightsom and others (USGS, 2022).

    Description

    This data release provides the reanalysis streamflow data from versions 1.2, 2.0, and 2.1 of the National Water Model structured for timeseries extraction. The impact of this is that user can query time series for a given NHDPlusV2 COMID without downloading the hourly CONUS files and extracting the sample of relevant values.

    The data is hosted on the RENCI THREDDS Data Server and is accessible via OPeNDAP at the follwoing URLs:

    Version 1.2 (https://thredds.hydroshare.org/thredds/catalog/nwm/retrospective/catalog.html?dataset=NWM_Retrospective/nwm_retro_full.ncml) - Spans 1993-01-01 00:00:00 to 2017-12-31 23:00:00 - Contains 219,144 hourly time steps for - 2,729,077 NHD reaches

    Version 2.0 (https://thredds.hydroshare.org/thredds/catalog/nwm/retrospective/catalog.html?dataset=NWM_Retrospective/nwm_v2_retro_full.ncml) - Spans 1993-01-01 00:00:00 to 2018-12-31 00:00:00 - Contains 227,903 hourly time steps for - 2,729,076 NHD reaches

    Version 2.1 (https://cida.usgs.gov/thredds/catalog/demo/morethredds/nwm/nwm_v21_retro_full.ncml) - Spans 1979-02-02 18:00:00 to 2020-12-31 00:00:00 - Contains 227,903 hourly time steps for - 2,729,076 NHD reaches

    Raw Data (https://registry.opendata.aws/nwm-archive/) - 227,000+ hourly netCDF files (depending on version)

    DDS

    The data description structure (DDS) can be viewed at the NcML page for each respective resource (linked above). More broadly each resource includes:

    • A 1D time array - hours since 1970-01-01 00:00
    • A 1D latitude array - coordinate (Y) information
    • A 1D longitude array - coordinate (X) information WGS84
    • A 1D feature_id array - NHDPlus V2 COMID (NWM forecast ID)
    • A 2D streamflow array - Q (cms) [feature_id, time]

    Online Comic Platform Market Outlook



    The global market size for the Online Comic Platform Market is anticipated to grow from USD 3.2 billion in 2023 to USD 7.5 billion by 2032, reflecting a compound annual growth rate (CAGR) of 9.7%. This growth is driven by increasing digitalization and the rising popularity of online content consumption. The market is witnessing significant traction due to the shift from traditional print comics to digital platforms, fueled by technological advancements and the increasing proliferation of smartphones and tablets.



    The first significant growth factor for the online comic platform market is the increasing penetration of the internet and the widespread use of smart devices such as smartphones and tablets. With more individuals having access to high-speed internet and affordable smart devices, the consumption of digital content, including comics, has surged. This shift is particularly pronounced among younger demographics who prefer the convenience and accessibility of digital platforms over traditional print media. The ease of access to a plethora of comic genres and the availability of interactive features further enhance the user experience, driving market growth.



    Another critical growth factor is the evolving business models within the online comic platform market. Subscription-based models, ad-supported content, and pay-per-view options offer flexibility to consumers, catering to different preferences and budgets. Subscription-based models provide users with unlimited access to a vast library of content for a monthly fee, which is attractive to avid readers. Ad-supported models, on the other hand, allow free access to content with advertisements, making it accessible to a broader audience. Pay-per-view models cater to those who prefer to purchase specific titles. These diverse business models ensure a steady revenue stream for platform providers and content creators, fostering market expansion.



    The growing popularity of webtoons, a form of digital comics optimized for mobile devices, is another significant driver for the online comic platform market. Originating from South Korea, webtoons have gained immense popularity worldwide due to their unique vertical scrolling format, which is ideal for reading on smartphones. The success of webtoons has spurred the adoption of similar formats in other regions, contributing to the global expansion of the online comic platform market. Furthermore, the integration of multimedia elements such as animations and sound effects in webtoons enhances the reading experience, attracting more users to the digital comic realm.



    The world of online comics is not just limited to traditional formats; it has expanded into various forms of Comic Derivatives. These derivatives include adaptations and spin-offs that leverage popular comic characters and storylines, creating new content that appeals to diverse audiences. For instance, many digital platforms are now exploring the potential of animated series and interactive games based on popular comic franchises. This trend not only broadens the scope of storytelling but also enhances user engagement by offering a multi-dimensional experience. As a result, the market for comic derivatives is becoming an integral part of the online comic ecosystem, driving further innovation and growth.



    Regionally, North America is expected to hold a significant share of the online comic platform market, driven by the high adoption rate of digital media and the presence of major market players. Asia Pacific is projected to exhibit the highest growth rate, fueled by the increasing popularity of webtoons and the rising number of internet users. Europe is also anticipated to witness substantial growth due to the growing demand for digital content and the increasing preference for online comic platforms among younger audiences. Latin America and the Middle East & Africa are expected to experience moderate growth, supported by improving internet infrastructure and growing digital literacy.



    Type Analysis



    The Online Comic Platform Market can be segmented by type into Subscription-Based, Ad-Supported, and Pay-Per-View. Subscription-based models have gained significant traction, offering users unlimited access to a vast library of comics for a monthly or annual fee. This model provides a steady revenue stream for platform providers and content creators, making it a sustainable business model. Consumers are drawn to the convenience and cost-effectiveness of subs

Description

A crosswalk table between NHDPlus version 2.1 flowlines (using the unique field COMID) and the Watershed Boundary Dataset (WBD) 12-digit-hydrologic units (HU-12) is provided for the 48 contiguous United States. The crosswalk table provides a WBD HU-12 assignment for every networked flowline in the NHDPlus. In this way, the network developed for navigation and modeling, NHDPlus, is aligned with accounting units of the WBD HU-12s to the extent possible given the assumptions that were made in creating each. A crosswalk table for NHDPlus isolated sinks was produced by a simple overlay process where the sinks were assigned HU-12 values based on their position relative to the WBD snapshot HU-12s. This table was integrated with the flowline associations into one crosswalk table for both feature types. There is good alignment between aggregated NHDPlus catchments and WBD HU-12 units in many locations. These are areas where the flows and chemical or nutrient loads that are accumulated leav ...
