Document Summary
Coastal processes: waves, application of hjulstrom diagram, wave motion, wave action, erosion by: Corrosion (same as fluvial: force of erosion dependent on the type of shoreline. High gradient (bluffs) resists: morphology of coast controls these processes. Shape: net process is always to make the shoreline smoother. Bending the wave: sediment transport, how does sediment get there, longshore drift (fig. 17. 28: beach drifting, deposition, when is sediment deposited, think back to hjulstrom diagram. Backwash slower than swash: erosional features particularly in the great lakes basin, this relates to mass wasting processes, landforms of sea cliffs (fig. 17. 24: shore protection, coastal stabilization structures, groins, jetties, breakwater. Wind (aeolian) processes: arid landscapes, generally related to bluffs in unconsolidated material (glacial hill, erg (sand, reg (stones, hamada (rock, erosional (differential weathering, aeolian processes, the effect of wind as an agent of erosion. From aiolis (the greek god of wind: as with any fluid process:
