Indira Gandhi Canal

This file contains a digital map of the Indira Gandhi Canal (India) in Google Earth KMZ format that was produced as part of The IBT Water Project at Auburn University. The Indira Gandhi Canal was primarily designed to support irrigation in the Thar Desert region of the state of Rajasthan in western India. Originally called the Rajasthan Canal, the project was renamed in 1984 in honor of the former Prime Minister Indira Gandhi. Stage I of construction began in 1952 and was completed in 1983. This stage is described as consisting of a 204 km feeder canal and 189 km main canal (393 km total). Stage 2 extended the main canal an additional 256 km. Construction appears to be ongoing today as the extent of water distribution expands. As of 2021, the canal appears to feature approximately 200 diversions to secondary distribution canals of varying sizes and approximately 45 control gates to manage flow rates and assist in diverting water to the secondary canals.

本文件包含采用谷歌地球KMZ（Google Earth KMZ）格式的印度英迪拉·甘地运河数字地图，该数据集系奥本大学（Auburn University）IBT水项目的研发成果。英迪拉·甘地运河最初旨在为印度西部拉贾斯坦邦（Rajasthan）的塔尔沙漠（Thar Desert）区域提供灌溉支撑。该工程最初名为拉贾斯坦运河，1984年为纪念前总理英迪拉·甘地而正式更名。

一期工程于1952年动工，1983年竣工，该阶段工程包含204千米的输水干渠（feeder canal）与189千米的主渠，总长度共计393千米。二期工程将主渠延长了256千米。当前随着配水范围不断扩大，该运河工程仍在持续建设中。

截至2021年，该运河共设有约200个适配不同规模二级配水渠的分水口，以及约45座节制闸，用于调控水流流速并辅助向二级配水渠分水。
