Gullfoss 古佛斯瀑布

Gullfoss is one of the most popular tourist attractions in Iceland. The wide Hvítá rushes southward, and about a kilometre above the falls it turns sharply to the right and flows down into a wide curved three-step "staircase" and then abruptly plunges in two stages (11 m and 21 m) into a crevice 32 m (105 ft) deep. The crevice, about 20 m (66 ft) wide, and 2.5 km in length, extends perpendicular to the flow of the river. The average amount of water running down the waterfall is 140 m³/s in the summer and 80 m³/s in the winter. The highest flood measured was 2000 m³/s.

During the first half of the 20th century and some years into the late 20th century, there was much speculation about using Gullfoss to generate electricity. During this period, the waterfall was rented indirectly by its owners, Tómas Tómasson and Halldór Halldórsson, to foreign investors. However, the investors' attempts were unsuccessful, partly due to lack of money. The waterfall was later sold to the state of Iceland, and is now protected.

古佛斯瀑布（冰島語：Gullfoss，冰岛语意为“黄金瀑布”）位于冰岛西南部南部区境内，瀑布分为两部分，高度分别为11米和21米。夏季平均流量为100～180 m3/s，冬季则为50～110 m3/s，最大流量达2000 m3/s。

Seljalandsfoss 塞里雅兰瀑布

Seljalandsfoss is one of the best known waterfalls in Iceland. Seljalandsfoss is located in the South Region in Iceland right by Route 1 (Iceland) and the road that leads to Þórsmörk Road 249. The waterfall is one of the most popular waterfalls and natural wonders in Iceland. The waterfall drops 60 meters and is part of the river Seljalands-river that has its origin in the volcano glacier Eyjafjallajokull. One of the interesting things about this waterfall is the fact that visitors can walk behind it into a small cave.
