In this tutorial, we will guide you through the process of creating IDF (Intensity-Duration-Frequency) curves for different durations and AEPs (Annual Exceedance Probabilities). Using the TRMM 3H rainfall data, we will demonstrate how to generate these curves, which are crucial for hydrological and infrastructure design.

IDF curves provide essential information for assessing rainfall intensity and frequency over a specific duration and return period. By understanding these curves, engineers, urban planners, and researchers can make informed decisions regarding drainage systems, stormwater management, and infrastructure resilience.

In this video, we will explain the step-by-step process of creating IDF curves, including data collection, preprocessing, and analysis. We will showcase how to utilize the TRMM 3H rainfall data, which is widely used in hydrological studies due to its global coverage and long-term records.
