摘要：The solid transport on the water supply canals of the Razelm . Sinoe hydrotechnical system, represents a very important matter for the hydraulics and hydroameliorative activity; there is a permanent risk of their chocking and even their decommissioning. On the basis of the solid flows computation relations used in the present paper, more concepts were taken into account: relations based on knowing the stimulating unitary effort of the silt particles from the riverbeds and knowing the friction unitary effort; relations based on knowing the critical velocity of the solid particles stimulating current and the medium velocity of the current in section; relations based on the statistics theory of the silt stimulating, empirical relations; relations based on energetic concepts etc. Between the liquid and solid flows, there were conducted correlations for each flash flood, a phenomenon with difficult to set loop because of the silt transportation process, but also because of its temporary nature. Out of the liniar correlation computations between the annual average values of the liquid flows and the annual average turbidities in a time interval of more than 25 years, conducted on the Dunavat, Dranov, Mustaca, Fundea, Fundata canals, it resulted a high degree of correlation scattering and particularly, the fact that between the liquid flow and turbidity there are correlations distinctive significant and significant
