This study investigates grain-size selective transport patterns in an alluvial, headwater watershed with an ephemeral flow regime : the Walnut Gulch Experimental Watershed (WGEW) in south-eastern Arizona. The aims of this study are (1) to identify if the concentration of transported sediment exhibit grain-size selective transport patterns, (2) to quantify how the grain-size selective transport patterns, if present, are different from the mean pattern of the total sediment load and from one another, (3) to explore the dependency of grain-size selective transport patterns on metrics of flow strength, duration, and sediment source, and (4) to determine if the grain-size selective transport patterns significantly affect watershed sediment delivery
