2 P. S, U2 ~7 mLake 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: 5 n7 F; L8 y2 ^# Q) ^5 K

Rawls Creek is a year-round stream that flows into the Saluda River a short distance downriver from the dam. How much flooding will occur in Rawls Creek from a dam failure, and how far back will it extend? * ^8 m, _5 q- z" W: G: S- @; M

位于美国南卡罗莱纳州中部的Murray 湖是因为发电需要而建造的一座大型土坝而形成的,大坝建成于1930 年。假设一场灾难性的大地震造成大坝决口,试对由此而产生的下游洪水进行建模。两个值得注意的问题:
