Hydrologic Controls in Nitrate, Sulfate, and Chloride Concentrations

摘要: Nitrate-nitrogen, SO 4 , and Cl concentrations discharge rates from a small, upland watershed in east central Pennsylvania were analyzed the context of layered aquifer. A pattern greater NO 3 -N during periods was generally followed by declining hydrograph recession. The coincident temporal appears hydrologically controlled because both exhibited similar patterns even though there are important differences their behavior reactivity biologically systems. Chemical concentration stream flow arose through two-layer geologic system which different between layers
