Ideas in this flowchart

• Stratified soils alter the movement of water
• Abrupt changes in soil texture occur between layers
• Texture contrasts can slow or redirect water flow
• Water moving from a coarse layer into a fine layer slows and spreads out
• Water moving from a fine layer into a coarse layer may remain in the fine layer until saturation
• Strongly contrasting layers can restrict downward water movement
• These layers can form aquitards or aquicludes
• Restricted flow can create perched water tables
