The capacity of PK piano weir is 4-5 times higher than conventional weir. This paper describes some hydraulic tests on the low-height P.K. weirs Type A, in order to show that it is possible to build in a drainage canal such a weir, which also improves safety and takes less labor to operate the system. The results of the performed tests can be used in practice as a design hydraulic feature for this weir type (the length of weir, the length of jump). In some cases, an adaptation of these tests could be required.
