Give me examples of drainage features

Here are some examples of drainage features: Rivers and Streams: Natural flowing watercourses that carry water from higher elevations to lower ones, eventually emptying into larger bodies of water like lakes or oceans. Lakes and Ponds: Bodies of standing water that collect runoff from surrounding land, forming part of a drainage system. Swamps and Marshes: Types of wetlands characterized by slow-moving or stagnant water, often acting as natural filters and temporary storage for water. Drainage Basins (or Watersheds): Areas of land where all surface water converges to a single point, such as a river, lake, or ocean. Gullies and Ravines: Channels formed by the erosive action of flowing water, often found on hillsides, which help direct surface runoff. That's 2 down. 3 left today — send the next one.
