A revised procedure for discharge measurement by means of the salt dilution method

Abstract

Abstract Discharge measurement by means of injection of a NaCl‐solution and integration of the electrical conductivity as a function of time is a traditional and well‐documented method for use in turbulent streams. The ease of the chemical measurements permits results to be calculated in the field. This work has shown that dry fine‐grained salt may substitute the salt solution. Correction factors for water temperature and background conductivity are derived from experiments. A simple procedure for calculation of the discharge is described.
