  • A procedure for classifying textural facies in gravel‐bed

    Textural patches (i.e. grain‐size facies) are commonly observed in gravel‐bed channels and are of significance for both physical and biological processes at subreach scales. We present a general framework for classifying textural patches that allows modification for particular study goals while maintaining a basic degree of standardization.
