Water discharges in small turbulent streams are determined by injecting concentrated salt solutions at constant feed-rate and measuring the dilution level downstream by conductivity readings in situ. This new-formed method is comparable with the traditional relative salt-dilution method, as well as with other methods, with respect to accuracy. In small streams with complicated hydrodynamic structures the new-formed method seems to be most practical and reliable.
