Explain the formation of ox‑bow lakes, levees and floodplains using clear step‑by‑step diagrams that show how deposition and lateral erosion shape the lower course landscape.

Use 1:50,000 and 1:25,000 OS maps to identify lower course landforms by interpreting symbols, contours and river patterns to spot meanders, floodplains, levees and cut‑off features.

Calculate river gradient using contour lines and distance so pupils can apply real geographical skills to understand how slope influences velocity and deposition.

Apply 4‑ and 6‑figure grid references to locate river features with accuracy, enabling pupils to pinpoint landforms and describe their spatial relationships — a key GCSE mapping skill.

This lesson is skills‑rich, exam‑focused, and highly visual, giving pupils the confidence to interpret real OS maps while deepening their understanding of how lower‑course landforms develop.
