T/F: Rills are more than 75mm deep and are often the start of gullies - answer False: gullies are
more than 75mm deep
What factors impact rainfall erosion? - answer Climate events, soil erodibility, length of flow
down a slope, slope of land (critical), erosion control BMPs, sediment control BMPs
T/F: Clay is highly erodible - answer False
What is sediment? - answer The eroded material suspended in water or air
Flocculants - answer Chemicals added to a mixture to make suspended particles clump together.
