Longitudinal streambed profiles along the sides of piers at selected bridge sites in Montana Longitudinal streambed profiles along the sides of piers at selected bridge sites in Montana
The U.S. Geological Survey (USGS), in cooperation with the Montana Department of Transportation (MDT), collected longitudinal streambed profile data along the sides of piers at selected bridges in Montana. The streambed profile data extends upstream and downstream of piers so that local pier scour effects might be distinguished from more general geomorphic scour processes. Two or more...
Cross-section geometry data at selected bridge sites in Montana Cross-section geometry data at selected bridge sites in Montana
The U.S. Geological Survey (USGS), in cooperation with the Montana Department of Transportation (MDT), collected channel cross-section geometry data on the upstream and downstream sides of selected highway bridges in Montana. The cross-section data typically extend the full width of the streambed at the bridge opening and up the abutments so that local pier scour effects and more general
Landsat 8-9 Operational Land Imager (OLI) Level 2 Provisional Aquatic Reflectance Products, Collection 2 Landsat 8-9 Operational Land Imager (OLI) Level 2 Provisional Aquatic Reflectance Products, Collection 2
The U.S. Geological Survey (USGS) provides Level-2 Provisional Aquatic Reflectance (AR) Products through EROS Science Processing Architecture (ESPA) On-Demand Interface for the Collection 2 Landsat 8-9 archive. This dataset includes n=742 provisional AR products for the visible and near-infrared (VNIR) bands for the Operational Land Imager (OLI) sensor at 30 meters resolution coincident...
Estimated crop irrigation water use withdrawals in McMullen Valley Groundwater Basin, Arizona for 2024 Estimated crop irrigation water use withdrawals in McMullen Valley Groundwater Basin, Arizona for 2024
Observations of irrigated agricultural land within the McMullen Valley Groundwater Basin in Arizona. Crops were verified in situ four times in 2024 first on May 2nd, then on Aug 30th, Sep 10th, and finally on Dec 4th; based on digitized field boundaries. Field boundaries were digitized from U.S. Department of Agriculture, National Agriculture Imagery Program County Mosaic 2023 imagery...
Estimated crop irrigation water use withdrawals in Sierra Vista Groundwater Subbasin of the Upper San Pedro Groundwater Basin, Arizona for 2024 Estimated crop irrigation water use withdrawals in Sierra Vista Groundwater Subbasin of the Upper San Pedro Groundwater Basin, Arizona for 2024
Observations of irrigated agricultural land within the Sierra Vista Groundwater Subbasin of the Upper San Pedro Groundwater Basin in Arizona. Crops were verified in situ once in 2024 on Sep 11th; based on digitized field boundaries. Field boundaries were digitized from U.S. Department of Agriculture, National Agriculture Imagery Program County Mosaic 2023 imagery for Arizona and...
Deposit componentry and tephra grain shape data by dynamic-imaging analysis of the Kulanaokuaiki Tephra Member of the Uwēkahuna Ash, Kīlauea volcano, Island of Hawai‘i Deposit componentry and tephra grain shape data by dynamic-imaging analysis of the Kulanaokuaiki Tephra Member of the Uwēkahuna Ash, Kīlauea volcano, Island of Hawai‘i
Tephra samples from the Kulanaokuaiki Tephra Member (400 to 1000 C.E.) of the Uwēkahuna Ash (200 B.C.E. to 1000 C.E.) were sampled from Kīlauea volcano, Island of Hawai‘i. Samples were analyzed by dynamic imaging analysis using Microtrac CAMSIZER P4 and X2 instruments for grain shape and Anton nitrogen pycnometer instruments for density in the U.S. Geological Survey - Hawaiian Volcano...
