The Native American Research Assistantship Program—Building capacity for Indigenous water-resources monitoring The Native American Research Assistantship Program—Building capacity for Indigenous water-resources monitoring
Intertribal networks for collecting and analyzing hydrologic and environmental data are growing. The U.S. Geological Survey can be a key partner with Tribal Nations in the further development of network capacity. A first step is the internship opportunity available through the partnership between the USGS and The Wildlife Society: The Native American Research Assistantship Program.

A predictive analysis of water use for Providence, Rhode Island A predictive analysis of water use for Providence, Rhode Island
To explain the drivers of historical water use in the public water systems (PWSs) that serve populations in Providence, Rhode Island, and surrounding areas, and to forecast future water use, a machine-learning model (cubist regression) was developed by the U.S. Geological Survey in cooperation with Providence Water to model daily per capita rates of domestic, commercial, and industrial...
