In mountain regions like the Rockies, headwater streams make up more than 70% of the river network and support the downstream waterways and communities. … While these sources are crucial, very few are monitored, and aspects of their hydrology are not well understood. A team of researchers, including UConn Department of Earth Sciences assistant professor Lijing Wang, are working to determine what influences how and when water moves through these streams, and what hidden source sustains them long after the rush of snowmelt. Their findings are published in Water Resources Research.
