UAS imagery and related products collected for structure-from-motion work obtained by using uncrewed aerial systems from an erosion prone area north of Medina River Natural Area near San Antonio, Texas, August 14, 2019, and July 8, 2022 UAS imagery and related products collected for structure-from-motion work obtained by using uncrewed aerial systems from an erosion prone area north of Medina River Natural Area near San Antonio, Texas, August 14, 2019, and July 8, 2022
Uncrewed aerial system (UAS) flights were conducted by the U.S. Geological Survey at an edge-of-field site located north of Medina River Natural Area near San Antonio, Texas on August 14, 2019, and July 8, 2022, to support efforts aimed at estimating edge-of-field erosion and potential sediment loading into the Medina River near San Antonio. Data provided here include imagery obtained...

Temporal and spatial variability of water quality in the San Antonio segment of the Edwards aquifer recharge zone, Texas, with an emphasis on periods of groundwater recharge, September 2017–July 2019 Temporal and spatial variability of water quality in the San Antonio segment of the Edwards aquifer recharge zone, Texas, with an emphasis on periods of groundwater recharge, September 2017–July 2019
Ongoing urbanization on the Edwards aquifer recharge zone in the greater San Antonio area raises concern about the potential adverse effects on the public water supply from development. To address this concern, the U.S. Geological Survey, in cooperation with the City of San Antonio, studied patterns of temporal and spatial changes in water quality at selected surface-water and...
