Abstract:
One third of the world population lives in the coastal zone whose natural environment and ecosystems are directly impacted by the freshwater and sediment discharged by the rivers. Yet, the conventional method to estimate the river discharges is based on the record of the gauging station located closest to the river mouth, which could be hundreds of kilometers away; such a method is insufficient to produce accurate values. Here we present in-situ yearlong observations of the water and sediment discharges through a cross-section near the mouth of the Changjiang (Yangtze River). This data was first compared to the data obtained from the nearest river gauging station at Datong, and then used to derive two methods to accurately estimate the water and sediment discharges of the entire drainage basin.
