Estimating Flood for a Hydraulic Structure
- The return period is the average time between the occurrences of floods of a certain magnitude or greater.
- The designer must choose a return period for designing the hydraulic structure.
- The return period is usually expressed in years.
- The designer must also decide on the level of risk he is willing to accept for the design.
- The level of risk is usually expressed as a percentage.
- In this case, the designer is willing to accept 20% risk that the flood of that or higher magnitude will occur in the next 10 years.
Calculating the Return Period
- The designer must use statistical data to estimate the return period for the desired level of risk.
- The statistical data may include historical flood records, rainfall data, and other relevant information.
- The designer can use statistical methods such as the Gumbel distribution to estimate the return period.
- In this case, the designer must find the return period that corresponds to a 20% chance of a flood of that or higher magnitude occurring in the next 10 years.
Answer
- The correct answer is option 'C' which is 45 years.
- This means that the designer must choose a return period of 45 years for designing the hydraulic structure if he is willing to accept 20% risk that the flood of that or higher magnitude will occur in the next 10 years.
