Line-Events for coastal landforms identified in National Agricultural Imagery Program maps and the landforms’ relative vulnerability to horizontal erosion due to sea-level rise ranking are linear-referenced using 1:24,000-scale resolution U.S. Geological Survey National Hydrography Dataset (NHD ) Coastline vector data to create geodata to attribute the conterminous U.S. coastline, Using the Hydrographic Event Management (HEM) tool (https://www.usgs.gov/national-hydrography/tools).), The linear-referenced geodata track along the NHD Coastline in intertidal zones open to oceans, behind barrier coasts in bays, lagoons, and estuaries, and sometimes where tidal currents reach upstream (landward) of the embayed foreshore...

The National Hydrography Dataset (NHD) and Watershed Boundary Dataset (WBD) are used to portray surface water on The National Map. The NHD represents the drainage network with features such as rivers, streams, canals, lakes, ponds, coastline, dams, and streamgages. An important use of the NHD is the analysis of surface-water systems. This analysis is possible because many types of location information can be linked to the NHD, such as flow-volume, velocity, temperature, water chemistry, pollution control classifications, aquatic species habitat, recreation designations, or water rights. Such network-linked data is typically maintained by various organizations at Federal, State, and local levels, as well as research,...
A new and more complete version of this dataset can be found at https://doi.org/10.5066/P9QQTKA0. This dataset contains information about waterfall location and characteristics. It also provides a linear reference to two National Hydrography Datasets. This dataset is based off the World Waterfall Database (WWD) and other source datasets. The coordinates and spatial attributes from the WWD were used to help verify locations in Google Earth. From there, the USGS HydroLink Tool was used to link data to both the NHDPlusV2.1 (1:100,000 scale) and NHD High Resolution Dataset (1:24,000 scale). This dataset currently includes waterfalls from the states of Indiana, Wisconsin, Michigan, Nebraska, Illinois and Missouri....

Point Events are data that USGS has linked to the NHD. These include USGS stream gages, dams, hydrologic unit outlets, stream flow alterations, and water quality stations.
