Abstract

A river training structure includes a longitudinal groyne placed in the river. The groyne extends in flow direction of the river with water of the river along both longitudinal sides of the groyne. The river training structure includes blocks, each block being constituted by a central part and four or more legs extending from the central part such that the central part and legs define a three-dimensional configuration allowing a multiple of said blocks to inter-engage with each other three-dimensionally when stacked onto each other. The groyne is constructed from a multiple said blocks irregularly stacked onto each other and engaging with each other to form a dam body of inter-engaging blocks, the dam body having a longitudinal slope at the navigation channel side of the dam body.
