Hydrography is the branch of applied science which deals with the measurement and description of the physical features of oceans, seas, coastal areas, lakes and rivers, as well as the prediction of their change over time. It's all about mapping and charting navigable waters. Unlike hydrology, which focuses on the properties and movement of water, hydrography is concerned with the physical characteristics. Think of it as the cartography of aquatic environments. 🗺️ It’s crucial for safe navigation, resource management, and coastal zone planning.
