CPESC ACTUAL EXAM PAPER 2026
QUESTIONS WITH SOLUTIONS GRADED A+
◉ Sediment. Answer: Sediment is eroded material suspended in wind or
water.
◉ Sedimentation. Answer: deposition of eroded material
◉ Splash erosion. Answer: raindrop impact energy is enough to dislodge
surface sediments
◉ Sheet erosion. Answer: caused by rain splash detaching soil particles
lifting them up and removing them by shallow "sheets" of water flowing
down the sloped soil surface
◉ Rill erosion. Answer: as flow concentrates, small channels begin to
form in the soil surface
◉ Gully erosion. Answer: Formed when runoff cuts rills deeper and
wider or when flows from several rills come together and form a large
channels
,◉ Channel erosion. Answer: may become unstable due to increased
flows or changes in upstream sediment load
◉ Natural erosion. Answer: generally considered due to the influences
of climate on the surface of the earth
◉ Accelerated erosion. Answer: natural erosion + human activities
◉ What can accelerate erosion problems?. Answer: 1) unrestricted
development
2) removal of surface cover
3) increased imperviousness
4) poor stewardship
◉ Construction related erosion can?. Answer: 1) Cause probs for down
slope property owners
2) Create nuisance problems on adjacent streets
3) clog streams and storm drains
result in turbidity plums in down stream water bodies
4) cover sensitive habitat areas with sediment
◉ In stream damages include:. Answer: 1) destruction of spawning
areas, food sources, habitat
, 2) direct toxicity to wildlife
3) lake degradation
4) filling of nav channels
5) impacts to commercial fisheries
6) reduction of water storage
◉ Suspended material. Answer: sediment can affect light penetration,
channel stability, fisheries and habitat
◉ Clean Water Act (CWA). Answer: Federal Water Pollution Control
Act enacted to restore and maintain the chemical, physical and
biological integrity of the waters of the US
administered by USEPA
◉ Section 401 of CWA. Answer: requires any applicant for a federal
permit to conduct any activity, including the construction of operation or
a facility that may result in the discharge of any pollutant, must obtain
certification for those activities from the state which the discharge
originates. This is known as the water quality certification for the
project.
