Post-Fire Soil Water Repellency, Hydrologic Response, and Sediment Yield Compared between Grass-Converted and Chaparral Watersheds

Fire Ecology

Table 4 Rain events, duration, 15 minute rainfall intensity (I₁₅), and total event rainfall amount for 2003, 2004, and 2005 hydrologic years. Table represents rain events with total amounts >2.5 cm. No rainfall events <2.5 cm resulted in I₁₅ >3 mm hr⁻¹.
