Lesson 1Geomorphological natural hazards: floodplain inundation, slope instability, gully erosion, and mass-movement typesThis section explores geomorphological hazards such as floods, landslides, gully erosion, and mass movements. Students link triggering factors, terrain controls, and land use to hazard mapping, risk assessment, and mitigation strategies.

Learners link terrain metrics to erosion, landslide susceptibility, drainage development, and infrastructure planning in varied geomorphic settings.

Students relate drainage geometry to lithology, structure, relief, and long-term landscape evolution.

Learners interpret how folds, faults, and rock strength influence topography, drainage, and resource or hazard distribution.

Learners analyze meandering, braiding, avulsion, and floodplain building, linking process to channel pattern and management.

Learners relate climate indices to hydrologic regimes and water availability in diverse regions.

Learners evaluate resolution, accuracy, and metadata, and practice combining sources for regional landscape analysis.

Students learn to interpret imagery for landforms, drainage, vegetation, and surface moisture, and to recognize common processing artifacts and limitations.

Students relate parent material, texture, and structure to soil classification, fertility, drainage, and land use suitability across landscapes.
