Vertical dropshaft is an important element in hydraulic structures since it easily allows covering a vertical jump. In the present paper the problem faced is to quantify the phenomenonof air entrainment in vertical shafts: two methods are presented for the measurement of entrained air flow rate. The anemometric method is semi-classical, while the volumetric method is fully innovative. A deep analysis has been carried out concerning the principles on which the two methods are based and they are shown to be complementary methods. A comparison is also provided between the two methodologies.

Abstract
Vertical dropshaft is an important element in hydraulic structures since it easily allows covering a vertical jump. In the present paper the problem faced is to quantify the phenomenonof air entrainment in vertical shafts: two methods are presented for the measurement of entrained air flow rate. The anemometric method is semi-classical, while the volumetric method is fully innovative. A deep analysis has been carried out concerning the principles on which the two methods are based and they are shown to be complementary methods.
