Rains: A threat to the mountains

The effects of rain are huge around the world, including crop yields, river formation, and catastrophic floods. But the extent to which rain affects mountains has long been debated, but now experts A team from the University of Bristol in the UK has used a technique to help geologists understand the problem that the flow of water caused the highest Yen mountain on our planet. With the help of advances in this area, scientists have been able to calculate the rate of erosion caused by rain.

In this way they can better explain the relationship between structure and water in a particular area. Dr. Byron Adams, author of the Institute for the Environment at the University of Bristol, says that heavy rains make rivers flow faster in rocks. Mountains can take shape, but scientists also believe that rain can cause the earth to erode very quickly, with the inevitable result of rocks coming out of the ground and mountains rising rapidly. Experts have been researching these two concepts for decades, because the measurements needed to prove them are very complex.

Scientists say the findings, which focus on the Himalayas, the highest mountain range on our planet, also pave the way for predicting the effects of climate change on Earth and, in turn, on human life. ۔ The team of researchers has focused its efforts on the central and eastern parts of the Himalayas in Bhutan and Nepal, as this region of the world has become one of the inland scales to study the rate of erosion. More than selected.

Dr. Adams, an expert at Arizona State University (ASU) and Louisiana State University, teamed up to use the instruments used inside the sand particles to measure the rate of erosion of rocks beneath rivers. According to Dr. Adams, when a particle reaches Earth from space, it is likely to collide with sand particles on mountain slopes, as these particles are carried to rivers. When this happens, some atoms in each grain of sand can be transformed into a unique element.

We can calculate how many atoms of this element are in the bag and also know how long the sand has been there and therefore we can calculate how fast the erosion of the mountain is taking place. According to experts, once the rate of erosion over the entire mountain range reaches us, we can compare this rate with changes in river slopes and rainfall. Experts have observed the rate of erosion observed in Bhutan and Nepal. Several methods were used to recreate the style of. Only one of these methods accurately predicted the measured rate of deduction.

Thanks to this technique, we have, for the first time, been able to determine the amount of rain that affects the erosion process on uneven terrain. The results of the study show how important rainfall is when assessing the motion pattern of ground plates through geographical studies.

Thanks to them, progress has been made on the extent to which the slippage of ground plates can be controlled by surface erosion as a result of weather. According to scientists, the results of this study It can also be used to help with information on usage management, infrastructure construction and repair and other hazards.

There has always been a risk in these mountains that high rates of erosion could lead to a significant increase in the accumulation of soil behind the dams, which could jeopardize many hydropower projects. Shows that too much rain can damage mountain slopes, increasing the risk of debris flow and landslides.

Some of these landslides could be large enough to turn the river into a dam, creating a new risk of flooding from lake breakage. Dr. Adams says our data and analysis are based on mountainous areas such as the Himalayas. , I provide effective techniques for estimating the extent of erosion and thus are a valuable source of information about the hazards that affect the millions of people living in these mountains and their bases.

Experts are now looking at how this research could explain how mountain volcanic reactions are caused by large volcanic eruptions. Using their state-of-the-art methods to measure the rate and rock properties of orchids help How rivers and volcanoes have affected each other in the past. This will help us to more accurately assess how to deal with the effects of future volcanic eruptions on people living in nearby areas.
