The South Florida Water Management District (SFWMD) and the U.S. Geological Survey have developed projected future change factors for precipitation depth-duration-frequency (DDF) curves at 174 NOAA Atlas 14 stations in central and south Florida. The change factors were computed as the ratio of projected future to historical extreme precipitation depths fitted to extreme precipitation data from various downscaled climate datasets using a constrained maximum likelihood (CML) approach. The change factors correspond to the period 2050-2089 (centered in the year 2070) as compared to the 1966-2005 historical period. The SFWMD manages the water resources of various interconnected areas in south Florida, which are defined in the SFWMD ArcHydro Enhanced Database (AHED) as “AHED Rain Areas”. The SFWMD is interested in summarizing change factors for each individual AHED Rain Area to use in future planning efforts. Geospatial data provided in an ArcGIS shapefile named “AHED_basins.shp” are described herein. The shapefile contains polygons for the AHED Rain Areas defined in the South Florida Water Management District (SFWMD)'s ArcHydro Enhanced Database (AHED) including their acreages.

HydroJunctions are points that are created from the endpoints of HydroEdge features plus additional strategic locations on the flow network. These include the location of Structures, Streams, QuadBasins, and MonitoringPoints projected to the flow network, as well as the centroids of waterbody polygons projected on the flow network. HydroJunctions are an important part of the Arc Hydro model in terms of creating the relationships among feature classes. It is through HydroJunctions that features in other feature classes are related to the network. HydroJunctions are created in the process of building the geodatabase, using a combination of manual and automated methods, as described in the methodology document. When new Structures, MonitoringPoints, QuadBasins, HydroEdges and Waterbodies are added to the database, new HydroJunctions need to be created. Date of last update: December 2013.

The Alberta ArcHydro Phase 2 Data was developed to support the delineation of catchment areas in the province of Alberta. It was generated using a DEM which had the Base Stream and Flow Representation (Single Line Hydrography Network) burned (excavated) into it. The data is divided into eighteen major basins across Alberta using an ArcHydro ID to relate the datasets.

Data were captured from USGS 7.5 minute mylar separates containing the "blue-layer" from the U.S. Geological Survey's 1:24000-scale quadrangle maps.Waterlines features updated in 2019 using Arc Hydro extension for ArcGIS Pro and 2018 Digital Elevation Model

This datasets contain GIS files related to the hydrology and watersheds of Accomack and Northampton Counties on the Eastern Shore of Virginia. Data include named and unnamed water bodies, rivers and streams (both center flowlines and area polygons showing bank-full width for larger features), wetlands and marshes, and shorelines. A static (2013-09-06) copy of the full USGS "National Hydrography Dataset (NHD) - High Resolution - Virginia" state-extracted dataset in original ESRI file-geodatabase format, downloaded on 2014-02-21 from nhd.usgs.gov, is included. For users who may not be able to read or make use of data in ESRI proprietary geodatabase formats, shapefiles of geographic feature classes contained within the HUC8 subbasins spanning Accomack and Northampton Counties (partly or wholly) are also provided. Note that the stream network nodal topology, which can be used to evaluate and analyze flow paths as part of a fully-functional hydrological network with GIS tools such as Arc Hydro and Network Analyst, are only available within the ESRI file-geodatabase file. The primary purpose of this dataset is to provide VCRLTER researchers and students with a convenient up-to-date set of GIS data layers in one location that can be used as base layers for various map products and for conducting research activities. A secondary purpose of this dataset is to extend hydrologic data coverage in the VCRLTER data catalog to include Accomack County and to supersede older USGS DLG data contained in the Northampton County GIS data package (VCRLTER dataset VCR14219).

Modeled treatment areas within the Barrow Biocomplexity study area. Data were derived using the Digital Elevation Model derived for the study area from airborne Light Detection and Ranging (LiDAR) data in the Arc Hydro extension to ArgGIS 9.2. Treatment areas were defined from the catchment area of the thaw lake basin and the location of the dikes that were installed to separate the basin in to the different treatment areas. The northern treatment area became the flooded treatment, the central area the drained treatment area and the southern treatment the control area.

The Heihe River Basin (HRB) is an inland watershed in northwest China with a total area of approximately 130,000 km(2), stretching from the Qilian Mountains in the south to the oases and agricultural fields in the middle and further to the Gobi desert in the north bordering Mongolia. As part of a major ecohydrological research initiative to provide a stronger scientific underpinning for sustainable water management in arid ecosystems, a regional-scale integrated ecological and hydrological model is being developed, incorporating the knowledge based on the results of environmental isotope tracer analysis and the multiscale observation datasets. The first step in the model development effort is to construct and calibrate a groundwater flow model for the middle and lower HRB where the oases and vegetation along the Heihe river corridor are highly dependent on groundwater. In this study, the software tool Arc Hydro Groundwater' is used to build and visualize a hydrogeological data model for the HRB that links all relevant spatiotemporal hydrogeological data in a unified geodatabase within the ArcGIS environment. From the conceptual model, a regional-scale groundwater flow model has been developed using MODFLOW-2005. Critical considerations in developing the flow model include the representation of mountainous terrains and fluvial valleys by individual model layers, treatment of aquifer heterogeneities across multiple scales and selection of proper observation data and boundary conditions for model calibration. This paper discusses these issues in the context of the Heihe River Basin, but the results and insights from this study will have important implications for other large, regional groundwater modelling studies, especially in arid and semiarid inland river basins.
