Data source description

   In 1966, the runoff discharge at Jiangjia Ravine in Baishapo and Xiadawa was estimated based on manually measured flow area and velocity. From 2004, the suspended-sediment concentration and grain size distribution were measured in Xiaojiang River at different locations. From 2012, the sediment concentration and sediment grain size distribution of runoff were measured at Jiangjia Ravine. A water sample was manually collected with a volume of 500 ml, and then sediment contained within the sample was filtered, dried, and weighed. Sediment concentration was determined by comparing the weight of the sediment to the total sample weight. Particle size analysis of the sediment was conducted using a Malvern laser particle size analyzer (Model MS2000).

Data processing method

   Raw observational data, unprocessed.

Data quality description

  The data quality is reliable.
