Horizontal Loss Rate Modeling on Matter Content in Marine Bay with and without Source Input

Taking chromium (Cr) in surface waters in Jiaozhou Bay in August 1981 as an example, this paper provided Horizontal loss rate modeling on matter content in marine bay with and without source input. Results showed that in the case of source input, the horizontal loss rate of Cr was 10.99-36.00 YDFa and 11.94-19.45 YDFr. In the case of no source input, the horizontal loss rate of Cr was YDFa and 0.00-1.30 YDFr. If there was source input, both Absolute Amount and Relative Amount were relative high, resulting in rapid settlement of Cr from surface waters to bottom waters, and the status of Cr contents in waters were tending to be returning to levels without source input. If there was no source input, both Absolute Amount and Relative Amount were relative low, resulting in little settlement of Cr from surface waters to bottom waters, and the status of Cr contents in waters were tending to be keeping to levels without source input.
