Probability, risk and uncertainty analysis for hydrological design

It gives a framework that is financially critical for finding the exceptional designs of hydrological systems with a reduced cost in total inclusive of the project cost and the disaster mitigation cost. But there would be hardly any assessment of a decent quality damage function. Hence, errors in demonstrating the hydrologic events, incorrect model parameters, and so on may occur. Here, we will discuss a specific hydrological design that of a detention basin for studying and understanding the risk-based procedure, uncertainties, and probability analysis by following a systematic framework.

Question

The image displays a graph titled "Rainfall Intensity-Duration-Frequency Curves for Singapore Island." The graph is used to predict precipitation intensity for different durations and return periods.

**Axes Details:**
- The horizontal axis represents "Rainfall Intensity" measured in millimeters per hour.
- The vertical axis represents "Time" in minutes, ranging from 10 to 120.

**Curves:**
- Several curves correspond to different return periods, such as 2 years, 5 years, 10 years, 25 years, 50 years, and 100 years.
- Each curve shows how the intensity of rainfall changes with duration for a specific return period.

**Task:**
- Use the IDF (Intensity-Duration-Frequency) curve to predict the precipitation intensity for a rainfall event:
- With a 50-year return period at a duration of 80 minutes.
- With a 100-year return period at a duration of 90 minutes.

The user would trace the corresponding curve for the specified return period and duration to find the rainfall intensity on the graph.
