About
Location, capacity, and completion year information is provided for 158 large dams situated in China. The data offers key statistics for crucial infrastructure projects, including structural height, storage capacity, and the year construction was finalised. Originating from Muhammed Tausif's Dams And Reservoir collection, this version has been cleaned, with capacity (in million cubic meters) and height (in meters) converted to standardised float values for consistent analysis.
Columns
- Name: The specific identifier or common name of the structure.
- Region: The province or political region where the structure is situated. Yunnan and Sichuan are among the most frequently listed provinces.
- Second Province: Details the bordering province, used for simplification when counting dams across provincial lines. Note that information in this column is mostly missing (94% null).
- Impounds: Identifies the river or reservoir upon which the dam is constructed, such as the Yellow River or Jinsha River.
- Height: The vertical dimension of the structure, quantified in meters. Heights range significantly, with a mean around 133 meters.
- Type: Categorises the structure based on its primary design, such as Gravity, Arch, or Concrete-face rock-fill.
- Storage Capacity: Represents the maximum volume of water the reservoir can hold, measured in million cubic meters.
- Year of completion: The year the dam structure was fully built. The year 2008 appears frequently in this data.
Distribution
The information is typically supplied as a single data file, such as a CSV format. It contains 158 unique records spanning 8 distinct fields. Core metrics, including height and storage capacity, have been verified and validated across all 158 records. The dataset is expected to be updated annually.
Usage
This resource is ideal for various analytical purposes, including infrastructure planning, large-scale engineering studies, and environmental impact assessments related to water storage. It can be used to track regional distribution of large projects and analyse construction trends over time. Users can study the variety of structural types used in Chinese hydro projects, for instance, noting that Gravity dams constitute the largest percentage.
Coverage
The data exclusively covers fixed dam structures located within the geographical boundaries of China. There is no specific time limit, but the 'Year of completion' field provides a historical scope detailing when these structures were finished. The provinces of Yunnan and Sichuan are highly represented in the location data.
