What is Temperature and precipitation control the seasonal patterns of discharge and water isotopic signals of the Nyang River on the southeastern Tibetan Plateau about?
River hydrology on the southeastern Tibetan Plateau (SETP) is particularly sensitive to climate change, through the serious impacts of the decline in Indian summer monsoon (ISM) rainfall and the accelerated melting of snow and glaciers during the recent decades. Investigating the effects of meltwater and rainfall on the seasonality and quantity of river runoff in the region is crucial for improving regional hydrological monitoring and water management, and water stable isotopes can provide an effective method. Based on the event-based data of precipitation and river water isotopes, river discharge and meteorology monitored at a hydrometric station of the Nyang River on the SETP in 2011, we show that river discharge has a strong reliance on temperature and precipitation simultaneously through their controls on the meltwater and rainfall runoff, and river water deuterium excess (d) and δ18O potentially track the meltwater and rainfall effects separately. The seasonal signals of river discharge and isotopic data provide evidence that meltwater is the key factor of river discharge and isotopic changes during the pre-ISM season (low water level period) and ISM rainfall during the early
