The Huaihe River

The core technique of flood forecast and pre-warning of a river basin is the numerical simulation of flood process in a complicated flood control system. According to the structural features, flood features, and flood process mechanism of a large and complicated flood control system, a 1D and 2D coupled numerical simulation model was established. The 1D model was used for the trunk river and main branches, and the 2D model was used for flood districts. The coupled 1D and 2D was used to simulate the flood regulation and process in rivers, lakes, flood districts, and floodways. A case study was conducted in the section from the Wangjiaba to Bengbu floodgates in the middle reach of the Huaihe River. The coupled model was employed to synchronously simulate the branch rivers and trunk flood of the river basin and to improve the accuracy of flood simulation, flood forecast, and regulation of the river basin. The parameters of the model for simulating the flood process of the Huaihe River Basin in 2003 were calculated and verified, and the flood process in 2007 was demonstrated. The simulated results show that the flood regulation and process can be accurately simulated by the proposed numerical model, and the accuracy requirements can be satisfied. Finally, the model was applied to the effect analysis of a four-grade emergency flood control plan in the Huaihe River Basin.

In the mid-1950's, fingernail clams virtually disappeared from a 100-mile section of the IL River, a tributary of the Mississippi River, due to unknown causes. A survey of the bottom fauna of the IL River in 1979, revealed that the clams were still absent from the middle reach of the River, where they had been abundant prior to the die-off in the 1950's. Some factor(s) in the River currently prevent the clams from recolonizing areas where they were formerly abundant. Recently, clams exposed to fluoride developed abnormal grooves in the shell matrix. Fluorides are known to be protoplasmic poisons removing essential body calcium by precipitation. Since the shell consists primarily of Ca carbonate, this investigation examines the possible role of fluoride on shell formation and the poisoning of the Ca pump which can directly inhibit lateral ciliary activity on the gill.
