Raft River monitor well potentiometric head responses and water quality as related to the conceptual ground-water flow system

Near-surface groundwater responses to injection of geothermal wastes

“…The designation as a r i v e r i s a misnomer because i t i s more accurately an ephemeral stream. (Allman e t al., 1982).…”
