Packet 2: Bonus 16

This parameter is generally above 80 for non-porous soils with high clay content, corresponding to hydrologic soil group D. For 10 points each:
[10h] Name this empirical parameter introduced by the Soil Conservation Service that is used to estimate runoff. As this parameter increases, the potential maximum soil moisture retention decreases.
ANSWER: runoff curve number [or CN]
[10m] Hydrologic soil groups have differing curve numbers due to an “initial abstraction” parameter dependent primarily on this process in which soil absorbs water. Runoff occurs when rainfall exceeds this process.
ANSWER: infiltration
[10e] The curve number decreases as the percentage of this soil component increases, as it allows for greater infiltration. Silt, clay, and this granular material comprise the inorganic component of soil.
ANSWER: sand
