Title

Evaluating and estimating the risk of erosion and sediment in Karaj basin using morphometric and experimental methods

Pages

  105-125

Abstract

 1-Introduction: There was about 15 percent of the world's soil erosion at the beginning of the twenty-first century that nearly 11 million square kilometers was affected by water erosion. Soil erosion after population growth is a serious threat to the environment, health and well-being of humans, and it has been introduced as the second most important environmental challenge in the world. The annual level of soil erosion in the world is 75 billion tons and Iran's share is more than 2 billion tons and about 3 times more than the total soil erosion which has been reported in Asia. On the other hand, the amount of soil erosion in north of Iran is 15 to 25 million tons per year, While the amount of forest per capita is 2. 0 hectares in Iran and 8. 0 hectares in the world. Soil erosion in the region of Asia, Africa and South America is 30-40 tons per hectare annually, in the United States and Europe is 13-17 tons per hectare and in Iran is 30-35 tons per hectare. The mean erosion in Iran is about 3. 4 times the average erosion in the world. In the present study, we used Fournier and Douglas models to predict the amount of sediment in the watershed of Karaj...
