Final answer:
A geomorphologist would be most helpful in a study of landscape change due to their expertise in earth's surface features and processes.
Step-by-step explanation:
The project that would likely require the assistance of a geomorphologist is a study of landscape change. Geomorphologists specialize in the study of the earth's surface features and processes that shape the landscape, making them particularly suited for projects related to landscape change. This type of study often involves examining biogeomorphology, which looks at the interactions between biological and geomorphological processes. Moreover, understanding the impact of anthropogenic activities, such as logging, is also part of a geomorphologist's expertise.
