Sheet- the soils ability to infiltrate water is exceeded and it runs in sheet flow
(about 100 ft before concentrating), how sediment gets transported
Rill- when sheet flow begins to concentrate, velocity and turbulence increase, but
easily repaired
Gully-when rills converge, larger than rill and usually requires heavy equipment to
repair
Channel- large volume of water increases the gully, vertical sides are observed or
for an existing streambed when structural integrity is destroyed
What are the factors of rainfall impact? - 🧠 ANSWER ✔✔Kinetic energy is
dependent on rainfall amount/intensity, raindrop diameter, and raindrop velocity
What are two damaging effects of rainfall impact? - 🧠 ANSWER ✔✔Causes soil
compression which reduces infiltration
Mainly occurs in May-Sept which is when disturbance is most active
4 factors influencing erosion - 🧠 ANSWER ✔✔climate
groundcover (influenced by humans)
soil properties
topography (influenced by humans)
