Writing a Summary of Article

This assignment is writing a summary of a published article, "Climate Change and Rainfall
Intensity—Duration—Frequency Curves: Overview of Science and Guidelines for Adaptation",
(Martel et al., 2021). You have to download the article from the website using the link provided
in the reference (highlighted). Please read the article thoroughly to understand the contents
and identify the most important details. Write a summary in your own words and avoid copying
sentences from the article. You have to mention the title of the article, name of the authors ,
the publisher, and the date of the publication. Your summary should include answers to the
following questions:

1. What is the research issue?

2. What are the rationales and objectives of the study?

3. What are the main points reviewed and discussed in this article?

4. What are the suggestions provided in this article?

Intensity-Duration-Frequency (IDF) under Climate Change
IDF curves are commonly used in engineering design. Due to climate change, IDF curves based
on historical observation are not adequate for the robust infrastructure design and making
long-term decisions. The Environment and Climate Change Canada (ECCC) recommends to use a
scaling methodology for accounting climate change impacts to extreme rainfall and IDF curves.
The detailed methodology is available on the website at:
You have to estimate future rainfall intensity value (Rp) using the equation, Rp = Rx 1.07";
where, Rc is historical estimated rainfall intensity, and AT is annual mean temperature change.
You can get historical rainfall intensity for a specific storm duration and return period for your
study area (location) from the IDF curve available on the website at:
For a future period and RCP scenario, you can find annual mean temperature change from your
Assignment 2. In this assignment, you have to perform the following tasks:

1. Download and present IDF curves for your study area. Determine historical estimated
rainfall intensity for 1-hr storm duration, and 5-year, 10-year, 50-year and 100-year
return periods for your study area.

2. Determine future estimated rainfall intensity (using the above mentioned equation)
over the period, 2041-2070 for 1-hr storm duration, and 5-year, 10-year, 50-year and
100-year return periods for your study area under RCP4.5 and RCP8.5 scenarios.

3. Calculate and obtain IDF curves based on historical observed precipitation for your study
area using the IDF_CC Tool 6.0 available at (MR Present your
IDF curves as a figure and compare results with the corresponding values from Task 1.

4. Calculate and obtain the updated IDF curves (using the above mentioned tool) based on
CMIPS GCMs data for the future period, 2041-2070 for 1-hr storm duration, and 5-year,
10-year, 50-year and 100-year return periods of your study area under RCP4.5 and
RCP8.5 scenarios. Download and present the tabular results and IDF curves, box-plots as
well as compare results with the corresponding values from Task 2.
