dc.description.abstract 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 groundbased 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,” is the headwater of more than 10 large rivers that provide water for billions of people and numerous ecosystems (Fig. 1). The TP has an average elevation greater than 4000 m and an approximate area of 2.5 × 106 km2 . It is largely covered by cryospheric components (glaciers, snow, and frozen soil), and is highly sensitive to climate change [3,4]. Due to the TP’s rapid warming in recent decades, prominent glacial recession, snowmelt, and permafrost degradation have occurred, resulting in water cycle modifications, as well as variations in streamflow both over the plateau and in its downstream regions [5]. en_US
