Activity 01
Modeling: Catchment Land Use Effects
Provide trays with soil; groups add vegetation, paving, or bare ground to simulate upper course changes. Pour measured water and time runoff to a lower 'floodplain' model. Compare flood depths and discuss real UK river links.
Analyze how land use in the upper course of a river affects flood risk in the lower course.
Facilitation TipDuring Modeling: Catchment Land Use Effects, circulate to ask guiding questions like, 'How does the soil type change your tray’s runoff speed?' to focus observations.
What to look forPresent students with a scenario: 'A town in the upper course of a river has approved a large new housing development with extensive paved areas. How might this decision impact flood risk in a downstream, densely populated town?' Facilitate a class discussion where students identify causes and effects, referencing concepts like impermeable surfaces and increased runoff.
