Certified Pool Operator Exam Bundle | Graded A

Certified Pool Operator Exam Bundle | Graded A Smaller, lighter particles such as __________________ particles are easily transported and are _____________________ to settle out. (Unit 1) - ansClay-sized; slow/difficult The Five Principles of Erosion and Sedimentation Control are: -____________ the development to fit the natural site conditions -Expose the ________________ practical area for the _________________ possible time -Apply __________ _________________ prevention practices as first life of defense -Apply ___________________ control practices to prevent off-site sedimentation -Implement a thorough __________________, ___________________, and _____________________ program. (Unit 1) - ans- Plan - Smallest; shortest - Soil erosion - Sediment - Inspection, maintenance, and follow-up The most effective way to prevent erosion is keep the soil covered with __________________. (Unit 1) - ansVegetation It is much more effective to prevent ____________ than to control the ____________________ generated from erosion. (Unit 1) - ansErosion; sediment When developing a runoff and SESC strategy, remember that _____________ and ________ _______________ control is more effective and cost efficient than _______________ control. (Unit 2) - ansrunoff; soil erosion; sediment Without proper planning, a construction generally results in an _______________ in runoff. (Unit 2) - ansIncrease. ____________________ controls rarely reduce ________________ or ___________________. (Unit 2) - ansSediment; runoff; erosion. Erosion and sedimentation may cause: -Loss of ___________ _______________ -__________________ damage to roads, buildings or bridges. -___________________, resulting in reduction of fish _______________ _________, reduced _____________ or _______________ _______________ capacity, and ______________ costs to maintain ______________. -_________________ loading. (Unit 1) - ans- fertile topsoil - Structural - Deposition; spawning areas; channel; storm drain; increased; turbidity - Pollutant The climatic factors that strongly influence erosion and runoff are _______________ amount, _______________, and ________________. (Unit 1) - ansRainfall, frequency, intensity. Soil properties influencing erodibility include: (Unit 1) - ansTexture, structure, cohesion, natural drainage class Texture refers to the ___________ or _____________________ of ____________ of soil particles in soil. (Unit 1) - ansSize; combination of sizes Structure refers to the degree to which individual soil particles _____________ to each other. (Unit 1) - ansAdhere Slope _________________, _____________________, and ___________________ affect erodibility. (Unit 1) - ansSteepness, length, and roughness. Sediment deposition occurs when soil-laden wind or water ____________ enough to allow the soil particles to settle out. (Unit 1) - ansSlows The ____________, _______________, and ________________ of the transported particles influence the rate at which they settle out. (Unit 1) - ansSize, shape, and density. Fine sediment particles, such as __________ and ___________, are difficult or impossible to capture with standard ________________ control techniques. It is particularly important to emphasize __________________ and __________________ control on sites with fine textured soils. (Unit 2) - ansSilts, clays; sediment; runoff, erosion. List five construction practices that minimize runoff and control erosion: (Unit 2) - ans List five sediment control practices: (Unit 2) - ans _____________, sometimes called _________________ is part of scheduling. This is where grading and stabilization are finished in one area before proceeding to the next area. (Unit 2) - ansStaging, phasing. The slope of a diversion channel must be adequate to provide good positive __________________ but not so great to create water velocities that will _____________ the diversion channel. (Unit 2) - ansDrainage, erode. Overland flow that is diverted must be disposed of without causing __________________ or ___________________ _____________________ where it is undesirable. (Unit 2) - ansErosion, depositing sediment. Runoff may be disposed of onto ___________________________ vegetation. (Unit 2) - ansWell-established. ___________________ _____________________ structures are used to carry runoff from one level to another. (Unit 2) - ansGrade stabilization. ______________________ occurs when water erodes small channels under or along the side of a water conveyance structure. (Unit 2) - ansPiping. ____________ ____________ are often used in roadside ditches to reduce the velocity of water. (Unit 2) - ansCheck dams.
