This thesis explores the role of morphology in regulating cold gas reservoirs in galaxies by uniquely combining two-dimensional structural decompositions with observations of atomic hydrogen gas (HI) for an unprecedentedly large and unbiased sample of local galaxies. It is revealed that the bulge fractions of star-forming galaxies have a negligible impact on their average HI content. Additionally, the bulge fraction alone does not explain the suppression of star formation observed in high stellar mass galaxies, nor the population of extremely star-forming galaxies. This thesis introduces the application and verification of novel techniques necessary for future improvements in galaxy morphology.
