لماذا تنحني الأنهار

unique visual element of mature Rivers is the Meander it's winding and curving but how do rivers curve when water comes from its source it takes the path of least resistance going downhill whenever it can when river reaches flat Plains it will continue to go straight until there is some sort of disturbance either by animals or different type of rock once it begins to curve Newton's first law of motion becomes involved since an object in motion such as water continues to be in motion until acted upon by something else the river's forces do not automatically Bend with the course of the river instead the water continues at full force Straight Ahead until it hits the outer part of the Curve this section is cut bank and erosion is prominent and strong as the river continues to erode the cutbank slowly changing the course of the River on the outside curve water on the inside curve begins to slow down since rapidly moving water is able to carry heavier objects the slower water becomes the more sediment and debris is deposited the water on the inside curve slows down dropping different for forms of sediment and rock over time this forms new land called Point bars as result of both cut Banks and point bars the river's course is diverted once this process happens once it Alters the direction of water causing the same process to repeat itself which is why there's rarely one curve on river when the river meanders it often meanders so much that different parts of the river bump into each other naturally the river takes the path of least resistance and the long Loop becomes useless the river then deposits sediment separating the loop from the main river if this Loop dries out it is meander scar if water remains it is known as an oxbow lake or in Australia bilabong and until next time thanks for watching
