Gravel Mining and Safeguard

Streams are susceptible to a great amount of problems that can be caused by gravel mining. These waterways have formed inside their valleys over a great number of years. For the duration of this period, the stream roamed across its flood plain. For the reason that the movement of the stream channel occurs at a very slow pace over a great number of years, natural erosion takes place at a rate to which the stream is able to adapt to. The features of any given stream are not created on hot summer days when there is only a small amount of water flowing in the channel. In its place, some streams are carved out throughout times when the stream channel is flowing at least half full. Through high flow, the water has an adequate amount of power to bring about certain changes. Streams are a chain of sporadic deep areas also known as pools and shallow areas are known as riffles. Riffles are high areas of the stream bottom that control the slope of the stream. It is the riffles that help control the slope of the stream in order for them to work to direct erosion. In most cases, erosion takes place on outside bends and silt, sand and gravel deposition comes about on the inside bends. This process causes the wiry characteristics that can be seen as we float, fish or swim in our preferred choice of a stream. Gravel mining in many cases results in loads or pits that, all through high water occurrences, can quickly add to the erosive process in streams. Even though a lot of our streams have loads of gravel left over, there are also a lot of streams that simply cannot afford to have gravel separated from them. To make sure you are mining from a stream that has sufficient gravel, look for some important features. Streams with too much gravel in most cases have gravel bars that have little or no vegetation growing on them. The rocks are in the main small, which should be less than three inches in diameter and are not tightly packed. Gravel bars where you are able to see vegetation or in places where the rocks are tightly packed are qualities of healthy streams with just the accurate quantity of gravel. These should not be bothered. When convenient, rock aggregate should be obtained from non stream sources for instance close by rock pits, however if you are required to remove sand or gravel from a stream or its flood plain, in any case do it in ways that will not hurt the property.
