Geodetic measurements using a two-color Electronic Distance Meter made in California, 1975 to 2005 Geodetic measurements using a two-color Electronic Distance Meter made in California, 1975 to 2005
Measurements of changes in the distance (or length) between monuments are provided. These measurements were made using a two-color Electronic Distance Meter (EDM) that can measure distances between 1 and 10 KM. Nominal precision of these data range from 0.3 mm to 1.0 mm dependent upon the baseline’s length. These measurements were made between mid-1975 to mid-2006. Data in this archive...
Bathymetry of Bubbly Creek and Chicago Sanitary and Ship Canal Sidings in Cook County, Illinois, July 2023 Bathymetry of Bubbly Creek and Chicago Sanitary and Ship Canal Sidings in Cook County, Illinois, July 2023
These data are high-resolution bathymetry (riverbed elevation) in compressed LAS (*.laz) format, generated from the July 17–19, 2023, hydrographic survey of Bubbly Creek and various sidings, harbors, and turning basins on the Chicago Sanitary and Ship Canal (CS&SC) in Cook County, Illinois. The survey includes all Bubbly Creek from the confluence with the CS&SC in the north to the Racine...
North Branch Chicago River and North Shore Channel Bathymetry in Cook County, Illinois, July 2023 North Branch Chicago River and North Shore Channel Bathymetry in Cook County, Illinois, July 2023
These data are high-resolution bathymetry (riverbed elevation) in compressed LAS (*.laz) format, generated from the July 17–18, 2023, hydrographic survey of the North Branch Chicago River and North Shore Channel in Cook County, Illinois. The survey extends from near the North Avenue Turning Basin and Goose Island in the south, upstream to the Metropolitan Water Reclamation District (MWRD...
Array detections and physical captures for three native fishes in the Little Colorado River in Grand Canyon, AZ Array detections and physical captures for three native fishes in the Little Colorado River in Grand Canyon, AZ
These data were compiled to monitor native fishes (particularly humpback chub Gila cypha) in the Little Colorado River, in the Grand Canyon, AZ. Objective(s) of our study were to evaluate the timing of native fish migration and the abundance of migratory and resident fishes between the Colorado and Little Colorado Rivers in the Grand Canyon. These data represent encounter histories for...
Geologic Map of the valley corridor of the Niobrara National Scenic River, Nebraska Geologic Map of the valley corridor of the Niobrara National Scenic River, Nebraska
This release of digital geologic map data covers the Niobrara National Scenic River, a 76-mile stretch of river at the northern edge of the Nebraska Sand Hills. The mapped area includes the National Park Service unit of the Niobrara National Scenic River and the adjoining Middle Niobrara Preserve of The Nature Conservancy, and the Fort Niobrara Wildlife Refuge of the U.S. Fish and...
Identifying structural priors in a hybrid differentiable model for stream water temperature modeling at 415 U.S. basin outlets, 2010-2016 Identifying structural priors in a hybrid differentiable model for stream water temperature modeling at 415 U.S. basin outlets, 2010-2016
This model archive (Rahmani et al. 2023a) provides all data, code, and model outputs used in Rahmani et al. (2023b) to improve model representations toward improved prediction of stream temperature and groundwater/subsurface flow contributions to stream temperature. Briefly, we modeled stream temperature at sites across the continental United States using a hybrid differentiable model...
