2 cards from this section. Quick, good the night before a test.
What does the decay constant (k) represent in Horton's equation?
Think about what happens to infiltration capacity after rain starts.
Explain how Horton's equation can be used to manage irrigation practices.
Consider the importance of knowing when soil reaches saturation.
What does the decay constant (k) signify in Horton’s equation?
Consider its role in infiltration behavior over time.
Horton’s Infiltration Index is primarily used to estimate:
Think about what the index aims to simplify in hydrologic analysis.
If f0=15 mm/hr and fc=3 mm/hr, given k=0.3, what would the infiltration rate be after 5 hours?
Calculate e^{-1.5} first to find the rate.
Discuss the implications of using only the initial infiltration capacity when applying Horton's Index in urban planning.
Consider why urban areas require precise rainfall runoff predictions.
