Abstract

The channel responses of the Inner Mongolian Reach to operation of its upstream reservoirs have different patterns. First, the Yanguoxia and Sanshenggong reservoirs, with their storages of 2.2×108 and 0.5×108 m3, respectively, reduced the sand-transport capacity from 7.33 to 6.27 kg·m-3, thus transforming a naturally net aggradational river channel into one in which erosion rate (<0.01 mm) was more than deposition rate (>0.01 mm). Also, the river channel was degraded and coarsening. Second, the Liujiaxia and Qintongxia reservoirs, with their storages of 57×108 and 5.7×108 m3, respectively, reduced the sand-transport capacity to 3.91 kg·m3. Thus, AS was larger than FS. Such a process may accelerate the alluvial process of the riverbed. Third, the Longyangxia reservoir, with its storage of 247×108 m3, reduced the sand-transport capacity to 3.48 kg·m-3, thus transforming the river channel into one in which both AS and FS may increase. The river channel elevation was as much as that in the pre-reservoir period.
