Paths to Runoff

Two narrow channels of runoff weave their way through leaf litter in a deciduous forest floor

In this section we will describe the paths that water can take to the basin outlet. We will look at details about surface runoff, interflow, and pre-event water. We will also consider influences of climate, geography, and pre-event moisture.

In this section you will learn to:

  • Identify the different types of runoff that occur both at and below the surface
  • Recognize the influence of surface and soil properties that influence surface runoff
  • Understand the soil properties that influence subsurface runoff, or interflow
  • Anticipate the types of runoff you may expect in your area given the rainfall/snowmelt rate and the soil properties
