The trapping of sediment is necessary when\nintense sediment transport occurs during floods that may endanger urban areas\nat downstream river reaches. In turn, the unwanted permanent trapping of\nsediment during small, non-hazardous floods can result in the ecological and\nmorphological degradation of downstream reaches. This study experimentally\nanalyses a novel concept for permeable sediment traps. For ensuring the\nsediment transfer up to small floods, a guiding channel implemented in the\ndeposition area of a sediment trap was systematically studied. The bankfull\ndischarge of the guiding channel corresponds to a dominant morphological\ndischarge. At the downstream end of the guiding channel, a permeable barrier\n(check dam) triggers sediment retention and deposition. The permeable barrier\nconsists of a bar screen for mechanical deposition control, superposed to a\nflow constriction for the hydraulic control. The barrier obstructs hazardous\nsediment transport for discharges that are higher than the bankfull discharge\nof the guiding channel without the risk of unwanted sediment flushing\n(massive self-cleaning).<\/jats:p>","DOI":"10.5194\/nhess-18-647-2018","type":"journal-article","created":{"date-parts":[[2018,3,2]],"date-time":"2018-03-02T03:57:22Z","timestamp":1519963042000},"page":"647-668","source":"Crossref","is-referenced-by-count":27,"title":["Sediment traps with guiding channel and hybrid check dams improve controlled sediment retention"],"prefix":"10.5194","volume":"18","author":[{"given":"Sebastian","family":"Schwindt","sequence":"first","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0265-8581","authenticated-orcid":false,"given":"M\u00e1rio J.","family":"Franca","sequence":"additional","affiliation":[]},{"given":"Alessandro","family":"Reffo","sequence":"additional","affiliation":[]},{"given":"Anton J.","family":"Schleiss","sequence":"additional","affiliation":[]}],"member":"3145","published-online":{"date-parts":[[2018,3,2]]},"reference":[{"key":"ref1","doi-asserted-by":"crossref","unstructured":"Allan, D.
