WebMeandering rivers produce suites of facies that vary depending on the subenvironment. Channel facies different from floodplain and ox bow lake facies because the flow characteristics and sediment supplies are different. Channel Facies Scoured base of flow Lag deposit with mud rip-up clasts and the coarsest grains being transported by the flow WebJan 1, 1989 · Using consistent field and analytical techniques, river planform facies models were derived for each of three contiguous reaches of the Squamish: braided, wandering and meandering. Sediment zones less than thirty years old were sampled systematically upon bars in each reach by digging holes to channel gravel depth or the water table.
