摘要

Mackay Dam is an irrigation reservoir on the Big Lost River, Idaho, approximately 7.2 kilometers northwest of Mackay, Idaho. Consequences of possible rupture of the dam have long concerned the residents of the river valley. The presence of reactors and management complex for nuclear wastes on the reservation of the Idaho National Engineering Laboratory (INEL), near the river, gives additional cause for concern over the consequences of a rupture of Mackay Dam.nThe objective of this report is to calculate and route the flood wave resulting from the hypothetical failure of Mackay Dam downstream to INEL. Both a full and a 50 percent partial breach of this dam are investigated. Two techniques are used to develop the dam-break model. The method of characteristics is used to propagate the shock wave after the dam fails. The linear implicit finite-difference solution is used to route the flood wave after the shock wave has dissipated.
