The Blue Nile merges with the White Nile near Khartoum in Sudan.

青尼罗河与白尼罗河在苏丹喀土穆汇合。

However, the source of the white Nile remained an elusive mystery for centuries more to come.

然而，在接下来的几个世纪里，白尼罗河的源头仍然是一个难以捉摸的谜。

In 1858, British explorers finally tracked down far enough to discover the white Nile source at lake Victoria in Uganda.

1858 年，英国探险家终于在乌干达的维多利亚湖发现了白尼罗河的源头。

The Nile has no true single starting place but is fed by two primary tributary rivers — the White Nile and the Blue Nile.

尼罗河没有真正意义上的单一发源地，而是由两条主要支流——白尼罗河和青尼罗河汇聚而成。

Overall, throughout the entire course of an average year, the Blue Nile contributes roughly 59% of all the water that makes its way through Egypt, while the White Nile contributes the remaining 41%.

总体而言，在埃及一年的平均用水量中，青尼罗河的水量约占 59%，而白尼罗河的水量则占其余的 41%。

These streams became known as the blue Nile and the White Nile, and by 1618, Spanish missionaries had finally discovered the source of the blue Nile down at lake tana in the highlands of Ethiopia.

这些溪流被称为蓝尼罗河和白尼罗河，到 1618 年，西班牙传教士终于在埃塞俄比亚高地的塔纳湖发现了蓝尼罗河的源头。

Eventually, the Blue and White Nile tributaries converge to the city of Khartoum in modern-day Sudan and then joined together to form the full Nile River from there all the way through Egypt and the Delta into the Mediterranean.

最终，青尼罗河和白尼罗河支流汇聚到现代苏丹的喀土穆市，然后汇合成尼罗河全河，从那里一路穿过埃及和三角洲，流入地中海。
