Best Practice Approach for Layouting Technical-Biological Bank Protections for Inland Waterways – PIANC WG 128

Abstract The worldwide increasing number of national guidelines and growing experience with realized green bank protections (constructions using insofar possible living or at least wooden construction material) in navigable waters, led to install a PIANC INCOM Working Group (WG) collect condense expert knowledge this field work prepare it for practitioners design purposes. corresponding report, called “Technical-Biological Bank Protections Inland Waterways”, is foreseen be released year. whose structure, content, key findings approach will highlighted briefly contribution the Smart Rivers Conference, tries overcome usual problems cases, which need civil engineers, eco-engineers ecologists altogether way how success stabilization measures noticed rated. WG members had notice that functionality assessment not simple, whereby partly huge differences between those who designed, maintained external parties as well cultural occurred. To these thus objectivize choice layout alternative solutions, may help convince people responsible waterway development maintenance use instead traditional riprap, Best Practice Approach was developed, based on catalogue numerous measures, are described e.g. so-called Fact Files. content descriptions, especially local boundary conditions (BCs shortly following) balance aims achieved issues, used assess suitability chosen measure under generally different than realizations. This inter alia by scoring system, assessing Design- (DC) Analysis Cases (shortly ACs from measures), Feasibility Check (it answers question, whether experiences made AC-cases can transferred DC) user-specified DC expected performance issues ACs, “Suitability Check” (answers far probably achievable). done both technical ecological scores were reviewed interdisciplinary internationally aforementioned differences.
