[origin: WO2019180359A1] A hydraulic structure comprises a shell (520) formed by concrete blocks (525b, 525m, 525h), the blocks each comprising at least one duct, in which the shell has a heterogeneous permeability, the shell being formed by first blocks (525b) having a first porosity, defined by a first number of ducts and/or by first duct dimensions of the first blocks, and at least by second blocks (525m) having a second porosity, which is different from the first porosity and defined by a second number of ducts and/or by second duct dimensions of the second blocks, the number of ducts in the second blocks being different from the number of ducts in the first blocks and/or the dimensions of the ducts of the second blocks being different from the dimensions of the ducts of the first blocks.
