Hydrologic maps are specifically designed to represent various aspects related to water resources, including the boundaries of river basins. These maps provide essential information on watershed delineation, drainage patterns, and the flow of water within a given area. By illustrating how water moves through the landscape and identifying the connections between rivers and their tributaries, hydrologic maps enable land surveyors and environmental scientists to understand the dynamics of water systems better.

In contrast, geographical maps focus more broadly on physical features and landforms without emphasizing water systems specifically. Nautical charts are tailored for navigation on water bodies, showcasing depth, hazards, and navigational aids rather than basin boundaries. Cadastral maps deal with property boundaries, land ownership, and land use, which do not pertain to river basin delineation. Therefore, hydrologic maps emerge as the most suitable choice for accurately displaying the boundaries of major river basins.
