张掖灌溉渠系数据集

数据概况：张掖的渠道分为干、支、斗、农、毛五级渠道，其中农渠一般没有衬砌，毛渠为田间工程，所以主要采集了干、支、斗三级渠道和小部分的农渠。灌溉渠系数据包括总干渠（涉及多个灌区）2条，总干渠（单个灌区内）和干渠157条、支渠782条、斗渠5315条，总长度8, 745.0km。 数据内容说明：...

Data Overview: The canals in Zhangye are divided into five hierarchical types: main canals, branch canals, lateral canals, farm canals and field ditches. Of these, farm canals are typically unlined, while field ditches are classified as field engineering works. Thus, this dataset primarily collects data from main, branch and lateral canals, along with a small subset of farm canals. The irrigation canal system data includes 2 main trunk canals serving multiple irrigation districts, 157 main trunk canals (within individual irrigation districts) and main canals, 782 branch canals and 5315 lateral canals, with a combined total length of 8,745.0 km.
