Discharge-driven seasonal pattern of ionic solutes, suspended sediment and water clarity for a tropical savanna river in northern Australia

River water quality is driven primarily by discharge and a catchment’s natural and anthropogenic features. In this study, the underpinning role of discharge in driving water quality is examined for an Australian tropical savanna river. The seventh-order Daly River has a near-natural discharge regime and catchment that is highly weathered, and has low topographic relief, with most of its natural vegetation retained. Four discharge periods are...
