An earlier paper by the author (Toward a theory of the morphologic significance of turbulence in the flow of water in streams, Univ. Calif. Pub. Geogr., v. 6, No. 1, 1932) presented a method of computing the distribution of intensity of turbulence in the plane cross-section of a stream, from surface-slope and distribution of velocity in the cross-section. In the present paper the results of such computation are compared with the results of computing the same measure of intensity of turbulence from measurements of turbidity by an equation derived by W. Schmidt (Der Massenaustausch in freier Luft und verwandte Erscheinungen, p. 62, 1925). This equation relates the vertical distribution of suspended matter in a column of turbulent fluid to the intensity of turbulence within the same column. The results given by the two procedures are in qualitative agreement. Moreover, assuming a typical vertical distribution of intensity of turbulence, the Schmidt equation, applied to the several fractions of a complex sample of suspended silt, gives results agreeing with the data of measurement such as those published by L. G. Straub (Trans. Amer. Geophys. Union, 1932, p. 379).
