On Using Artificial Rapid Hydraulic Structures (RHS) Within Mountain Stream Channels: Some Exploitation and Hydraulic Problems

Abstract

The chapter describes rapid hydraulic structure (RHS) with increased roughness: one of the technical solutions intended to maintain river and stream beds in a good condition and at the same time ensure the development of a braided channel and contribute to the regeneration of channel bar structures, creating suitable living conditions for macrobenthos, and enabling unconstrained fish migration without additional fish passes. The chapter also discusses the problem of rebuilding the existing water straight drop structure in Brenna on the Brennica River (Polish Carpathians) which was changed into the rapid hydraulic structure. The technical project was set up in 1988 and finished in the same year. The structure was rebuilt in the field in early autumn 1990. The author of the chapter was a co-designer of the hydraulic structure.© Springer-Verlag Berlin Heidelberg 2013.
