Information For Understanding Rock Waterfalls

Waterfalls take a long time to form in a river. A waterfall can be defined as a section of a river where there is a difference in height in two parts of the riverbed, causing water to drop vertically from the high end to the low end. The drops may occur in multiple locations along the course of the stream. Meltwater that is dropping over the edge of an iceberg is also called a waterfall. The term rock waterfalls is used if the drop is occurring over rock to form the feature.

Falls are predominantly formed in upper courses of a river where channels are deeper and narrower in width. The formation of this feature involves a river traversing a region with resistant rocks in its normal course of flowing. Because upstream water moves faster and slower downstream, whirlpools are formed. When the river comes across another area with soft rock after the resistant rock, the whirlpools start to gouge the soft rock, creating a step in its course. The step causes water to drop over when it reaches this point, forming a waterfall.

The stream above waterfalls usually becomes wider and shallower because of flowing over the rock shelf. The kinetic energy of the water that hits the ground below the waterfall usually dig it, causing a deep area below the feature. In most cases, a waterfall forms in a rocky place as a result of erosion. A horizontal pit that is parallel to the waterfall wall usually forms in the ground below the fall after a long time when the waterfall has developed fully.

Another method through which a waterfall may be formed is through gradual processes that take place in the course of the river. Such processes include soil erosion and earth movement. Earth movements may be caused by volcanoes, landslides, or earthquakes. These gradual processes result in differential land height which interfere with how rivers flow in their natural state. This forms a waterfall.

Waterfalls are of several different types. The various types are different from each other in various ways. Some have significant differences from one another while others have significant resemblance. Main types include ledge, plunge, horsetail, moulin, frozen, catadupa, segmented, cascade, staircase, and cataract waterfalls. Sub-types under a ledge waterfall are block, curtain, and classical falls. Main sub-types under a horsetail waterfall are ribbon, fan, slide, and chute water-falls.

In modern times, there are many uses for waterfalls. The most important of these uses is power generation. Turbines are usually connected in the dropping water so that its energy can be harnessed to rotate them. When the turbines are rotated, they generate electrical power, which is transmitted to various locations for industrial, commercial, and residential consumption.

In many places around the world, power is generated through this method. The disadvantage of this method of power generation is that, in case the water volume in the river goes down, the power generated can reduce significantly. Countries dependent on this mode of power generation usually ration power to their citizens during dry seasons.

The speed of the water beneath the fall is usually low, but the channel is deep. Fish favor such conditions for inhabiting. Therefore, local people usually fish in such waters because they have a lot of fish.
