Hydrological analysis in R

Hydrological analysis in R

# Chapter 1 Introduction

## 1.1 Practical outline

In this set of practicals, we’ll be using R, RStudio and WhiteboxTools to perform hydrological analysis.

In Chapters 2 and 3, we’ll install and get to grips with the required programs.

In Practical 1 (Chapters 4 - 6), which uses data for the **Eskdale** watershed, we’ll introduce you to some of the key approaches, including DEM pre-processing, calculating flow parameters and comparing flow algorithms.

In Practical 2 (Chapters 7 - 11), we’ll utilise these approaches to investigate the water quality of the **Mersey** Basin. This forms the basis for your assessment.

**Note**: the relevant chapters will be made available as we progress through the semester, hence why Practicals 2 and the assessment information are not currently visible. Practical 2 will be released prior to the Week 10 lecture.

## 1.2 Objectives

After completing these practicals, you will:

- have gained experience with new tools (e.g. R, RStudio, WhiteboxTools);
- become familiar with hydrological approaches used to simulate overland flow from digital elevation models (DEMs);
- utilised statistical analysis to investigate the relationships between water quality indicators and catchment characteristics;
- improved your understanding of the hydrological processes influencing water quality.

## 1.3 Schedule

These practicals will be completed across Weeks 8 to 12 as follows:

- Week 8:
- Introductory lecture (~1 hr)
- Complete Chapters 1 - 3: An introduction to R (~2 hr)

- Weeks 9:
- Lecture on Hydrological and Geomorphological models (~1 hr)
- Complete Chapters 4 - 6:
**Eskdale**practical (~2 hr, plus independent work)

- Weeks 10 - 12:
- Lecture on Water Quality Modelling (~1 hr)
- Complete Chapters 7 - 11:
**Mersey**practical (~6 hr, plus independent work)

The assessment, based upon Practical 2 (**Mersey**), is due 09/01/2025 (14:00).
