Imagery as Streamflow Data: Introducing the USGS Flow Photo Explorer (AD)
Flow is a critical variable in streams since it affects aquatic and riparian biological communities and human uses of water (i.e., recreation, public water supply, etc.). Flow regimes are changing due to anthropogenic (e.g., water withdrawals) and natural impacts (e.g., extreme weather events). Many states consider issues with altered hydrology as a growing priority and some have developed flow criteria for streams. However, most USGS gages are not located in small to mid- size streams and deployment of hydrological equipment is costly and requires specialized expertise. This project was created to help states, tribes and other entities by promoting a low-cost and user-friendly alternative with the use of continuous imagery for flow monitoring.
