This flow section includes an upper portion that includes set between the lateral walls, a structure for retaining material arriving from upstream, and a lower portion that identifies an opening for outflow. ## Claims ### Claim 1 A method for restraining debris in a stream, said method comprising providing a restraining structure comprising lateral walls which define wings extending from banks of the stream inwards and which delimit between them a flow section comprised in a bed of said stream, wherein said flow section includes an upper portion comprising a restraining structure, set between said lateral walls, for retaining material arriving from upstream and a lower portion defining a horizontal slit for outflow, the horizontal slit having a predetermined height between a bottom edge of the retaining structure and the stream bed, wherein the structure exerts an effect of lamination during a flood peak, wherein said predetermined height is selected as a function of a given maximum value of deposit upstream of the structure. ### Claim 2 A structure for restraining debris in a stream comprising banks, the structure comprising lateral walls which define wings extending from the banks of the stream inwards and delimiting between them a flow section comprised in a bed of said stream, wherein said flow section includes an upper portion comprising a retaining structure, set between said lateral walls, for retaining material arriving from upstream and a lower portion defining a horizontal opening for outflow, the horizontal opening having a predetermined height between a bottom edge of the retaining structure and the stream bed, wherein the structure exerts an effect of lamination during a flood peak, wherein said predetermined height is selected as a function of a given maximum value of deposit upstream of the structure. ### Claim 3 (depends on 2) The structure according to claim 2, wherein said retaining structure comprises a reticular structure. ### Claim 4 (depends on 3) The structure according to claim 3, wherein said reticular structure comprises a metal wire net. ### Claim 5 (depends on 3) The structure according to claim 3, wherein said reticular structure comprises elastic rings. ### Claim 6 (depends on 3) The structure according to claim 3, wherein said reticular structure comprises a net of ropes. ### Claim 7 (depends on 2) The structure according to claim 2, wherein said lateral walls delimit said flow section extending the flow section to an entire width of the bed of the stream. ### Claim 8 (depends on 2) The structure according to claim 2, wherein said lateral walls extend in the bed of the stream and delimit said flow section limiting the flow section to a partial width of said bed. ### Claim 9 (depends on 2) The structure according to claim 2, wherein said flow section is delimited at a bottom thereof by a slab. ### Claim 10 (depends on 9) The structure according to claim 9, wherein said slab and/or flow section are made of concrete or steel-cladded concrete or with bound rocks or boulders. ### Claim 11 (depends on 2) The structure according to claim 2, wherein said retaining structure is inclined in a downstream direction by an angle of between 10° and 30°. ### Claim 12 (depends on 2) The structure according to claim 2, wherein the lateral walls are non-permeable. ### Claim 13 (depends on 2) The structure according to claim 2, wherein the lateral walls have a different structure than the upper portion of the flow section. ### Claim 14 (depends on 2) The structure according to claim 2, wherein the horizontal slit extends an entire distance between the lateral walls and has a periphery bound on three sides by the lateral walls and the upper portion of the flow section. ### Claim 15 (depends on 2) The structure according to claim 2, wherein the retaining structure is at least partially permeable.
