黄河巴彦高勒-头道拐河段冲淤变化与分布
Variation and Space Distribution of Erosion and Deposition in Bayangaole to Toudaoguai Reach of the Yellow River
摘要
Abstract
Based on the measured cross data of Bayangaole to Toudaoguai reach,this paper computed the silted distribution of the main chan-nel and floodplain in different reaches and different periods by using cone method. The results show that:a)from 1962 to 2012,the total amount of sedimentation is 0. 863 5 billion tons in this reach,of which,0. 225 6 billion tons in the main channel and 0. 637 9 billion tons in the floodplain. During this period,the amount of sedimentation from Bayangaole to Sanhuhekou and from Sanhuhekou to Toudaoguai are 0. 169 2 billion tons and 0. 694 3 billion tons respectively. The sedimentation is mainly caused at the afflux reaches of ten tributaries. b)The most serious sedimentation is 0. 765 7 billion tons caused in the reach from Bayangaole to Toudaguai during 1982 to 2000,of which,0. 580 5 billion tons of siltation in the main channel and 0. 185 2 billion tons of siltation in the floodplain respectively. In this time,0. 240 3 billion tons of sedimentation is caused in the reach from Bayangaole to Sanhuhekou,of which,0. 200 1 billion tons of siltation in the main channel and 0. 040 2 billion tons of siltation in the floodplain separately. While 0. 525 4 billion tons of sedimentation is caused in the reach from San-huhekou to Toudaguai,of which,0. 380 4 billion tons of siltation in the main channel and 0. 145 billion tons of siltation in the floodplain. During this period,the sedimentation is mainly caused in the main channel,resulting in the serious deposition and shrinkage of the main channel,reducing the discharging capacity of floods and ice run and increasing the pressure of flood control.关键词
