经过数字处理的卫星图像发现了印度-巴基斯坦(印度-巴基斯坦)地区塔尔沙漠沙地下一条主要消失的河流的隐藏路线。古代印度文献中提到吠陀时期(公元前10000-8000年)的大喜马拉雅河。它在印度被称为“Saraswati”，在巴基斯坦被称为“Hakra”，在公元前4000-3500年间枯竭。大量来自哈拉帕文明的考古遗址出现在干涸的河床上。绘制的河流航道宽4-10公里，符合《梨俱吠陀》中描述的大小。新描述的过程通过在渠道中钻探管井以及通过考古、水文地质和沉积数据得到验证。在这些水道中发现了大量的饮用水。讨论了(主要)河道的路径、河流转移的可能性以及河流消失的原因。
Digitally processed satellite images have unearthed the hidden course of a major lost river below the sands of the Thar Desert, in the India-Pakistan (Indo-Pak) region. The great Himalayan river of the Vedic period (10 000-8000 BP) is mentioned in ancient Indian literature. It was called the 'Saraswati' in India and the 'Hakra' in Pakistan and it dried up during 4000-3500 BP. Large numbers of archaeological sites from the Harappan civilization occur along the dry river bed. The mapped course of the river is 4-10 km wide and conforms to the size described in the Rigveda. The newly described course is validated through the drilling of tube wells in the channels and through archaeological, hydrogeological and sedimentary data. An enormous quantity of potable water has been found along these channels. The path of the (main) river course, the likelihood of the river shift and the reasons for its disappearance are discussed.
