CPESC Exam Questions With Verified
Answers




What are the 5 factors that influence erosion? - answer✔Soil erodibility, topography, vegetative

cover, season, climate (rainfall)


What influences soil erodibility? - answer✔Soil texture, structure and % of OM


How does vegetative cover influence erodibility? - answer✔Top growth reduces raindrop

impact, filters sediment and slows down runoff velocity; roots hold mass particles together


How can you decrease erodibility in relation to topography? - answer✔Increase slope roughness


What climate characteristics affect erodibility? - answer✔Rainfall intensity, duration and

frequency


Why does frequent rainfall increase erodibility? - answer✔The soil becomes saturated and no

more water can infiltrate which increases runoff volume


Why is erosion potential high in the spring if it rains? - answer✔Water can't infiltrate the frozen

subsoil which increases runoff volume

What are some ways urban development impacts erosion hazards? - answer✔Changes hydrology

(GW flow, drainage), disturbs large amounts of soil, removes plant cover


BMP considerations for clearing and grubbing? - answer✔Preserve existing vegetation; clear

only what is required for immediate construction activity


BMP considerations for mass grading? - answer✔Create principle basins, traps, barriers,

diversions and channels; temporary stabilization; manage concentrated runon and runoff (water

bars)


BMP considerations for site access & off-hauling? - answer✔Stabilize with gravel and

temporary vegetation; limit ingress and egress points


What are the 3 stages of inlet construction? - answer✔Pipe installation, inlet construction, inlet

backfill


BMP considerations of channel construction? - answer✔Monitor weather, install grade controls,

stabilize streambanks early; consider time of year (weather) to start construction (phasing)


BMP considerations of final stabilization? - answer✔Immediately apply temp or permanent

stabilization of disturbed areas; don't allow surface area to dry out for a few days before seeding

(affects germination)


BMP considerations of vertical construction? - answer✔Protect inlets; modify plan to show new

conditions and updated measures
