A Numerical Simulation of Residence Time in Typical Gulf Substances in Guangxi
摘要
Abstract
In order to investigate the transport time scale in typical gulf substances in Guangxi, A transport numerical model is established and applied in the Qinzhou Gulf and the Tieshan Gulf and their adjacent areas. The residence time, semi-renewal period and their variation with different river discharges of these two gulfs are computed, meanwhile, the relationship between these two exchange time scales is discussed. The results show that the residence time and semi-renewal periods are about 413- 595 h and 148 –178 h respectively in the Qinzhou Gulf. The residence time in the Tieshan Gulf are about 215 –598 h, and the semi-renewal periods are about 50 h. The residence time decrease as river discharges increase. As river discharges change, the residence time in the Tieshan Gulf vary significantly under small river runoff conditions, and vice versa. The residence time vary linearly with the river discharge. No obvious functional relationship is revealed between the residence time and semi-renewal period in the Tieshan Gulf and the Qinzhou Gulf.关键词
