Lake Murray in central South Carolina is formed by a large earthen dam, which was completed in 1930 for power production. Model the flooding downstream in the event there is a catastrophic earthquake that breaches the dam. Two particular questions:

1、Rawls 河是一条四季不断流的、距大坝下游很近的Saluda 河的支流。当大坝决口形成洪水的时候,Rawls 河将遭受多大的洪水?河水倒流会延伸多远?2 u! a0 E& p$ s
2、洪水会波及位于Congaree 河边一座小山上的南卡罗莱纳州议会大厦吗? |
