About: Bedrock river

An Entity of Type: river, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

A bedrock river is a river that has little to no alluvium mantling the bedrock over which it flows. However, most bedrock rivers are not pure forms; they are a combination of a bedrock channel and an alluvial channel. The way one can distinguish between bedrock rivers and alluvial rivers is through the extent of sediment cover. The extent of sediment coverage is based upon the sediment flux supplied to the channel and the channel transport capacity. Bedrock rivers are typically found in upland or mountainous regions. Their formation can have several erosional factors.

  • النهر الصخري هو عبارة عن نهر لا يغطي فيه الغرين (رواسب نهرية) عادة صخر الأديم الذي يجري فوقه. وتكثر مثل هذه الأنهار في المناطق المرتفعة والجبلية. وهي تنتج عن الشقوق في صخر الأديم عن طريق كل من الكشط حيث تصطدم الرواسب الموجودة في التيار بقاع مجرى النهر وتزيل قطعًا من المواد و«استخراج» أو «اقتلاع» الحجارة حيث يتم اقتلاع كتل كبيرة من القاع (غالبًا بالقرب من سلاسل الصخور تحت الماء أو الشلالات) ونقلها في اتجاه التيار.
