In the Southeast US, El Niño Southern Oscillation (ENSO), climate variability phenomena affect the quantity of water that is available for irrigation. The goals of this study were to determine the effect of upstream surface water withdrawals for irrigation on the quantity of water available for irrigation in downstream areas as a function of the ENSO phase and quantify the watershed area that can be irrigated using water withdrawn from streams in an ecologically sustainable manner. The study was conducted in the Swan Creek watershed (97 km) located in Limestone County, Alabama, USA. The soil and water assessment tool (SWAT) model was used to simulate stream flows and develop water withdrawal prescriptions. Results indicated that when simultaneous water withdrawals were made at the outlet of each subwatershed throughout the year, on average water withdrawals were sufficient to irrigate 4–16% of the area upstream of withdrawal point depending on stream order. On making sustainable withdrawals at the outlets of all subwatersheds and at the watershed outlet throughout the year, approximately 40% of the watershed area could be irrigated.

基于 ENSO 的上游灌溉取水对下游取水的影响

在美国东南部,厄尔尼诺南方涛动 (ENSO) 气候变化现象影响可用于灌溉的水量。本研究的目标是确定上游地表取水灌溉对下游地区可用灌溉水量的影响,作为 ENSO 阶段的函数,并量化可以使用从河流中提取的水灌溉的流域面积。一种生态可持续的方式。该研究在位于美国阿拉巴马州石灰石县的 Swan Creek 流域(97 公里)进行。土壤和水评估工具 (SWAT) 模型用于模拟河流流量并制定取水处方。结果表明,当全年在每个子流域的出口同时进行取水时,平均而言,取水量足以灌溉取水点上游 4-16% 的区域,具体取决于河流秩序。在所有子流域出水口和流域出水口全年进行可持续取水后,流域面积约 40% 可灌溉。这是一篇根据知识共享署名许可 (CC BY 4.0) 条款分发的开放获取文章,该许可允许复制、改编和重新分发,前提是正确引用原始作品 (http://creativecommons.org/licenses/by/ 4.0/)。doi:10.2166/nh.2020.156 om http://iwaponline.com/hr/article-pdf/51/4/602/730616/nh0510602.pdf er 2020 Laljeet Sangha Jasmeet Lamba(通讯作者)Aumendra Kumar Biosystems Engineering Department大学,奥本,AL 36849,美国电子邮件:jsl0005@auburn.edu 在所有子流域出水口和流域出水口全年进行可持续取水后,流域面积约 40% 可灌溉。这是一篇根据知识共享署名许可 (CC BY 4.0) 条款分发的开放获取文章,该许可允许复制、改编和重新分发,前提是正确引用原始作品 (http://creativecommons.org/licenses/by/ 4.0/)。doi:10.2166/nh.2020.156 om http://iwaponline.com/hr/article-pdf/51/4/602/730616/nh0510602.pdf er 2020 Laljeet Sangha Jasmeet Lamba(通讯作者)Aumendra Kumar Biosystems Engineering Department大学,奥本,AL 36849,美国电子邮件:jsl0005@auburn.edu 在所有子流域出水口和流域出水口全年进行可持续取水后,流域面积约 40% 可灌溉。这是一篇根据知识共享署名许可 (CC BY 4.0) 条款分发的开放获取文章,该许可允许复制、改编和重新分发,前提是正确引用原始作品 (http://creativecommons.org/licenses/by/ 4.0/)。doi:10.2166/nh.2020.156 om http://iwaponline.com/hr/article-pdf/51/4/602/730616/nh0510602.pdf er 2020 Laljeet Sangha Jasmeet Lamba(通讯作者)Aumendra Kumar Biosystems Engineering Department University, Auburn, AL 36849, USA 电子邮件:jsl0005@auburn.edu 这是一篇根据知识共享署名许可 (CC BY 4.0) 条款分发的开放获取文章,该许可允许复制、改编和重新分发,前提是正确引用原始作品 (http://creativecommons.org/licenses/by/ 4.0/)。doi:10.2166/nh.2020.156 om http://iwaponline.com/hr/article-pdf/51/4/602/730616/nh0510602.pdf er 2020 Laljeet Sangha Jasmeet Lamba(通讯作者)Aumendra Kumar Biosystems Engineering Department大学,奥本,AL 36849,美国电子邮件:jsl0005@auburn.edu 这是一篇根据知识共享署名许可 (CC BY 4.0) 条款分发的开放获取文章,该许可允许复制、改编和重新分发,前提是正确引用原始作品 (http://creativecommons.org/licenses/by/ 4.0/)。doi:10.2166/nh.2020.156 om http://iwaponline.com/hr/article-pdf/51/4/602/730616/nh0510602.pdf er 2020 Laljeet Sangha Jasmeet Lamba(通讯作者)Aumendra Kumar Biosystems Engineering Department大学,奥本,AL 36849,美国电子邮件:jsl0005@auburn.edu
