Gumpe, Plunge Pool, or Stream Pool: Are They the Same Thing?
Water BodiesRivers are dynamic systems that shape the landscape around them through erosion and deposition. One of the most fascinating features of rivers are the pools that form along their course. These pools come in many shapes and sizes and are known by many names, including gumpe, plunge pool, and stream pool. However, many people are confused as to whether or not these terms refer to the same thing. In this article, we will explore the similarities and differences between gumpe, plunge pool, and stream pool.
The gumpe
A gumpe is a deep, cylindrical pool that forms in a river bed. It is usually found in areas where the river flows over hard rock or bedrock. The water in a gumpe is typically crystal clear and can be quite cold as it comes from underground springs. The depth of a gumpe can vary from a few feet to over 50 feet, depending on the size of the river and the geology of the area.
Gumpes are often associated with waterfalls because they form at the base of waterfalls where the water hits the riverbed with great force. The erosive force of the water carves out a depression in the rock that deepens and widens over time. Gumps can also form in areas where the river flows over a series of steps or ledges, creating a series of deep pools.
The diving pool
A plunge pool is similar to a gumpe in that it is a deep, cylindrical pool that forms at the base of a waterfall or other erosional feature. However, plunge pools are usually larger and shallower than gumpes. They are also more likely to be found in areas where the river flows over softer rock or sediment.
The water in a plunge pool is usually murky and turbulent because it is churned up by the force of the falling water. The depth of a plunge pool can vary from a few feet to over 100 feet, depending on the size of the waterfall and the geology of the area. Plunge pools can also be formed in areas where the river flows over a series of rapids or cascades, creating a series of pools connected by small waterfalls.
The stream pool
A stream pool is a broad, shallow pool that forms in a river channel. Unlike gumps and plunge pools, which are typically associated with waterfalls or rapids, stream pools can form anywhere along a river’s course. They are often found in areas where the river flows over a broad, flat floodplain or in meandering sections of the river where the water slows down.
The water in a stream pool is usually clear and calm because it is not stirred up by turbulence or erosion. The depth of a stream pool can vary from a few inches to several feet, depending on the size of the stream and the geology of the area. Stream pools are important habitats for a variety of aquatic plants and animals, including fish, insects, and amphibians.
Conclusion
In conclusion, while gumpes, plunge pools, and stream pools all refer to different types of stream pools, they share some similarities in terms of their shape and how they are formed. Gumpes and plunge pools are typically associated with waterfalls and other erosional features, while stream pools can form anywhere along the course of a river. Understanding the differences between these types of pools can help us appreciate the complex and dynamic nature of river ecosystems.
