  14. Factors affecting interception Weather characteristics Precipitation • amount • Intensity • Frequency • Duration

  15. Effect of precipitation amount on canopy and litter layer interception

  16. Rainfall Interception and Evaporation from Soil • Change in soil water storage over 40 days was simulated for bare soil, soil with 1X residue, and soil with 4X residue • Results illustrate a trade-off between rainfall interception and evaporation from soil Bussière, F., and P.
