Angel Falls, located in Venezuela, is the tallest waterfall in the world with a total height of 979 meters (3,212 feet). It is also known as Salto Ángel and was named after American aviator Jimmie Angel. The falls are located in the Canaima National Park, which is a UNESCO World Heritage Site.
Tugela Falls, located in South Africa, is the second-tallest waterfall in the world with a total height of 948 meters (3,110 feet). It is located in the Drakensberg mountain range and is fed by the Tugela River. The falls are divided into five separate tiers and are a popular destination for hikers and outdoor enthusiasts.
Tres Hermanas Falls, located in Peru, has a total height of 914 meters (2,999 feet) and is the third-tallest waterfall in the world. The falls are located in a remote region of northern Peru and are composed of three separate streams that flow into one another.
Olo'upena Falls, located in the United States, is the fourth-tallest waterfall in the world with a total height of 900 meters (2,953 feet). It is located in the Waimea Canyon State Park in Hawaii and is considered one of the most beautiful waterfalls in the world.
Yumbilla Falls, located in Peru, is the fifth-tallest waterfall in the world with a total height of 896 meters (2,940 feet). It is located in the northern region of Peru and is composed of four separate tiers. The falls were only discovered in 2007 and have since become a popular tourist attraction in the region.
How Waterfall Heights Are Measured
How waterfalls are measured depends on the location and accessibility of the falls.
1. Laser rangefinder or survey tools. The most common method used is to measure the distance between the highest point of the waterfall and the base of the waterfall. This is typically done using a laser rangefinder or a surveyor's level. However, this method can be challenging for waterfalls that are located in hard-to-reach areas, such as those located deep in the Amazon rainforest or high in the Himalayas.
2. Aerial photography. Another method used to measure waterfall heights is through aerial photography. This method involves taking photographs of the waterfall from a helicopter or drone and then using photogrammetry software to create a digital 3D model of the waterfall. This method is useful for waterfalls that are difficult to access on foot or where precise measurements are required.
3. Topographic maps and satellite imagery. In some cases, the height of a waterfall may also be estimated using topographic maps and satellite imagery. This method involves measuring the elevation difference between the top and bottom of the waterfall and then using mathematical calculations to determine its height.It's important to note that waterfall heights can vary depending on factors such as seasonal water flow, weather conditions, and erosion. As such, measurements are often taken at different times of the year to get a more accurate and comprehensive understanding of a waterfall's true height.
