Description

Data components

Folder "CRD v1.1" contains the recorded (5,143) reservoirs from yearbook and document data and all (97,435) reservoirs from CRD v1.1 (China Reservoir Database) two parts:

• CRD_v11_all_reservoirs (in both shapefile format and the comma-separated values (csv) format): This database catalogs the location information of 97,435 reservoirs in China, with an aggregated area of 50,085.21 km2 and an estimated total storage capacity of 979.62 Gt. The attributes of all the CRD v1.1 reservoirs (in all cases) include location information (longitude, latitude, province, prefecture, and county), inundation area, estimated storage capacity, river order, discharge, and residence time of reservoirs.

• CRD_v11_record_reservoirs (in both shapefile and csv): The 5,143 reservoirs in the CRD v1.1 database were directly derived from the yearbook and other documents data, accounting for 59% and 82% of the total reservoir area and storage capacity of the CRD v1.1 database, respectively. This reservoir information was mainly obtained through manual compilation. The attributes of the recorded reservoirs include the longitude and latitude of the reservoir, name, province, prefecture, and county where the reservoir is located, water area, water level of normal storage capacity, storage capacity, reservoir class, main use, and regulation type.
