资源简介：
The primary data consist of river width, river area, and centerline length for each section of the Lower Yalong River during wet and dry seasons. These data were obtained from remote sensing interpretation, validated by accuracy assessments against field measurements.The field data was collected from October 31 to November 2, 2004, covering a 3.89 km post-dam river section of the JP2 Dam, with 51 detailed survey transects set up. The arrangement of the transects prioritized data representativeness and distribution rationality, combined with onsite geological conditions, to achieve uniform distribution within permissible limits. Meanwhile, the water surface width at each transect was recorded.Water extraction part of the code:
