Problems Related to Infiltration and Relationship of Infiltration to Soil Function
MG
When rainfall
is received at a rate that exceeds the infiltration rate of a soil, runoff moves downslope or ponds on
the surface in level areas. Runoff on bare or sparsely vegetated soil can result in erosion. Runoff
removes nutrients, chemicals, and sediment, resulting in decreased soil productivity, offsite
sedimentation of bodies of water, and diminished water quality.
To determine whether runoff is likely to occur, refer to rainfall data [from Mead, NE and compare it to
the infiltration rate of [a loam (Table 3)] to determine whether the rate is adequate to [cause] runoff.
For example, tables 1 and 2 show the likely frequency (1 to 100 years) and duration of rainfall events
and the amount of rainfall received during each event at two locations in Nebraska.

1. For the Mead, NE data set plot frequency (years) on x-axis versus total 30-minute rainfall (in)
on y-axis. Connect the dots with a colored pencil. Label axes and include units in
parentheses. Include a title for your graph and a legend. If the average soil has a loam texture
(see Table 3 and note that the units are in inches/hour), how frequently is runoff occurring at this
location? (be specific, e.g. does it happen only every 10 years or at what frequency for this data
set?)
What general conclusion can you make about the frequency of the larger total rainfall
amounts?
