DAM BREAK ANALYSIS USING HEC-RAS

Abstract

Large weirs known as dams are constructed across rivers to store water and use it for a variety of purposes. For example, water can be supplied to different cities to meet their needs, and one of the main uses of dams is to generate hydroelectric power, which is a renewable energy source. Although dams offer many advantages, there is a chance that they could fail catastrophically, causing devastating floods and the loss of life and property. The process of evaluating the possible effects of a dam breakdown and creating backup plans to lessen its effects is known as "dam break analysis." This entails a thorough assessment of a number of variables, including the structural integrity of the dam, the amount and speed of water that would be discharged in the case of a failure, and the infrastructure and towns downstream that may be impacted. The significance of dam safety and break analysis has increased due to the aging infrastructure and the rising frequency of adverse weather events. Due to technological and modeling advancements, scientists and engineers have been able to create more thorough and precise ways for analysing dam breaks, which has enhanced disaster preparedness and risk reduction plans. The cooperation and knowledge of a wide range of experts, including engineers, hydrologists, geologists, emergency responders, and community stakeholders, are necessary for effective dam breach analysis. Proactively addressing dam safety and break analysis can lessen the likelihood of disastrous dam failures and safeguard downstream residents' lives and means of subsistence.
