Downstream fining - a literature review -

Abstract

In this report a detailed overview is given of the present knowledge about downstream fining. The influence of abrasion (chapter 2), selective transport (chapter 3), sediment addition, extraction and redistribution (chapter 4) is described and discussed. Then some attention is attained to a very striking downstream fining phenomenon, the rapid gravel-sand transition. Afterwards an overview is given of available numerical downstream fining models (chapter 6). The most important conclusions are summarized in chapter 7
