Hydrogeology

SID - PASI srl (PASI)

SID calculates hydraulic sections of any form and of any geometrical and hydraulic characteristics. The program determines, for a given section, the height and speed values reached by the water, assuming that the channel has a prismatic form of infinite length. The formula used by the program utilises the average velocity as a function of the mean radius of the section, that is equal to the ratio between the area of the hydraulic section and the wet boundary, of the loss of load and of the friction coefficient.
