Abstract: The influence of hydraulic parameter (Froude number, Fr) to water quality parameters is analyzed in order to provide a simple analytical tool which could be applied to area where the set of data measurement is scarce. Froude number is easy to obtained parameter and it relates to turbulence which could lead to the change of dissolved oxygen level. The study shows the numerical relationship between Fr and water quality in three different conditions of clean river, municipal river, and agricultural river respectively.
