New methods designed to estimate the daily discharges of rivers in the Tibetan Plateau

River discharge is a significant hydrological variable, as it represents the basin-scale integrated output of the hydrological cycle. At present, river discharge observations are usually measured at ground-based gauges across rivers worldwide. In some areas, however, measurements used in the practice of flood prediction and disaster prevention are either fully inaccessible or difficult to obtain in a timely and functional fashion (1)It has also been reported that the scarcity of global river discharge observations may have undermined the efforts to calculate a globally meaningful estimate of the adjusted biodiversity threat (2)The Tibetan Plateau(TP), also known as the ‘‘Asian Water Tower'.
