The USGS is developing innovative technologies and approaches for measuring river discharge using remotely sensed data. Given the expense associated with remote sensing from conventional aerial platforms (e.g., helicopter, airplane), unmanned aircraft systems (UAS) offer hydrographers a lower cost alternative for data acquisition.
Obtaining timely, accurate information on streamflow in Alaska’s rivers is difficult because gaging stations are sparse, with many located in remote inaccessible areas. Even for established gages, the maintenance and periodic measurements required to operate a gage are logistically challenging and can place personnel at risk, particularly during high flows.
The USGS Dakota Water Science Center is conducting high-resolution hydrographic mapping on two additional study areas in southeastern South Dakota.
As part of a Natural Resource Damage Assessment settlement related to contaminant releases from the Molycorp/Questa Molybdenum mine, subalpine fens, wetlands, and associated stream habitat for the native Rio Grande cutthroat trout are being restored in high-altitude headwaters of Bitter Creek, New Mexico.
The National Map Corps (TNMCorps), a crowdsourced mapping project, relies on volunteers to assist the USGS National Geospatial Program by collecting and editing man-made structures data for The National Map. Through their participation, volunteers make important contributions to the USGS’s ability to provide the Nation with accurate mapping information.
BOR is a key partner in the Trinity River Restoration Program (TRRP), located in far northern California. Remote sensing for the TRRP includes annual high-resolution aerial photography (0.5-foot pixel resolution), which provides a standard point of view for detecting morphological and vegetation changes to the river channel and floodplain.
The Atlantic Marine Assessment Program for Protected Species (AMAPPS) II is the continuation of a study to assess the abundance, distribution, ecology, and behavior of marine mammals, sea turtles, and seabirds throughout the U.S. Atlantic Outer Continental Shelf (OCS).
Archival aerial stereo-photographs are a source of information that can be used to create historical topography models for rapidly changing landscapes. Researchers completed a pilot study in Malakoff Diggins State Historic Park (MDSHP), which was once the largest hydraulic mine (1.6 square kilometers) in the Sierra Nevada of California. Legacy impacts in these mined landscapes include remnant steep exposures of highly erodible Eocene-aged auriferous sediments.
