Abstract: Phosphorus dynamics in a small river system have been measured to determine phosphorus transport mechanisms and correlation with hydrodynamic phenomena. Variation of chemical forms with flow conditions are related to point and diffuse sources and general equations derived. Mass balances are developed and diurnal changes are described.
