Rule structure

Weir in Landsberg am Lech

When straightening rivers, the increased flow velocity leads to a shift in the equilibrium between sedimentation and erosion . The resulting depression of the river bed, due to the vertical erosion, by regulating Structures of hydraulic engineering are avoided, which accumulate the water partially, thus reducing the effective gradient.

Types of standard structures are u. a .:

• Weirs
• Sleepers
• Sole sliding
• Base ramps
