Course of a River (50x70cm)

The “Course of a River (50x70cm)” chart is a mid-sized educational poster showing the journey and transformation of a river from its source to its mouth. It visually demonstrates the three classic stages of a river—upper, middle, and lower course—and the major landforms and processes that characterize each part.​

Key Features

The chart is organized into the three stages of a river:

Upper Course (near the source): Features steep gradients, fast flow, vertical erosion, V-shaped valleys, interlocking spurs, gorges, rapids, and waterfalls.​

Middle Course: The river becomes wider and deeper, with a gentler gradient. Notable features are meanders, wide U-shaped valleys, river cliffs (erosion on outer bends), slip-off slopes (deposition on inner bends), and oxbow lakes forming as meanders become exaggerated.​

Lower Course (approaching the mouth): The river reaches its widest and slowest part, with gentle slopes, significant lateral erosion and deposition, and the formation of floodplains, levees, deltas, and estuaries.​

Clear cross-sectional and plan diagrams are used to show channel shape, valley profile, and development of features like meanders and oxbow lakes.​

Includes labeled illustrations and concise explanations for each feature, often enhanced with visual examples or photographs.​

Laminated finish makes it suitable for group teaching, regular classroom display, or lab-based geography lessons.
