This thesis investigates the information contained in observations of neutral atomic hydrogen (HI) gas in galaxies. Measurement of disturbance in the HI is used to study how it relates to galaxy evolution. We find that HI disturbances are larger in galaxies with lower HI content, and those experiencing HI removal by their external environment. Otherwise, disturbances are ubiquitous and can have numerous causes. Most HI disturbances exist in the outskirts of galaxies, but the strongest ones can also affect their central regions. These results will aid future studies using next-generation HI surveys with the Square Kilometre Array.
