Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. A wall or plate placed in an open channel and used to measure the flow of water. The depth of the flow over the weir can be used to calculate the flow rate - or a chart or conversion table may be used to convert depth to flow. A wall or obstruction u






2. Most plumbing codes require a vent pipe connection of adequate size and located downstream of a trap in a building wastewater system. This vent prevents the accumulation of gases or odors and is usually piped through the roof and out of doors.






3. Sand - silt - gravel and rocks carried or washed into a collection system by infiltration water flows.






4. A large - public park - often highly scenic and isolated belonging to and operated by the federal government.






5. The oxidation ditch is a modified form of the activated sludge process. The ditch consists of two channels placed side by side and connected at the ends to produce one continuous loop of wastewater flow and a brush rotator assembly placed across the






6. A natural underground layer of porous - waterbearing materials (sand - gravel) usually capable of yielding a large amount or supply of water.






7. Water that may contain objectionable pollution - contamination - minerals - or infective agents and is considered unsafe and/or unpalatable for drinking.






8. A network of pipes - manholes - cleanouts - traps - siphons - lift stations and other structures used to collect all wastewater and wastewatercarried wastes of an area and transport them to a treatment plant or disposal system. The collection system

17. A coordinating agency formed in 1961 for state boards that administer licensing exams and maintain records for landscape architects to practice.






18. A sewer that discharges into a branch or other sewer and has no other common sewer tributary to it. Sometimes called a 'street sewer' because it collects wastewater from individual homes.






19. The slope of a plot of land. Grading is the mechanical process of moving earth changing the degree of rise or descent of the land in order to establish good drainage and otherwise suit the intent of a landscape design.






20. Opening in a sewer provided for the purpose of permitting operators or equipment to enter or leave a sewer. Sometimes called an 'access hole' or a 'maintenance hole.'






21. The movement of water through very small spaces due to molecular forces.






22. A groundwater table that has seasonal changes in depth or elevation.






23. A strip of unspoiled - often treed - agricultural or other outlying land used to separate or ring urban areas.






24. A road laid through a garden or park-like landscape - usually with median and roadside plantings.






25. Pertaining to groundwater - a well - or underground basin where the water is under a pressure greater than atmospheric and will rise above the level of its upper confining surface if given an opportunity to do so.






26. Masonry composed of roughly shaped stones fitting approximately on level beds - well bonded and brought at vertical intervals to continuous level beds of courses.






27. A biological wastewater treatment process which speeds up the decomposition of wastes in the wastewater being treated. Activated sludge is added to wastewater and the mixture (mixed liquor) is aerated and agitated. After some time in the aeration tan






28. A professional who designs - plans - and manages outdoor spaces ranging from entire ecosystems to residential sites and whose media include natural and built elements; also referred to as a designer - planner - consultant. Not to be confused with lan






29. A site that might appear to be natural but has elements and features that were planned and specified by a landscape architect. Designed landscapes include Central Park in New York to the siting of buildings.






30. The natural elements with which landscape architects work - such as plant materials and the soil itself.






31. An agency of the U.S. Department of the Interior charged with the planning and administration of all parks and monuments in the federal park system. The NPS is often referred to as the largest single employer of landscape architects in the United Sta






32. A wall that supports any vertical load in addition to its own weight.






33. Branch or lateral sewers that collect wastewater from building sewers and service lines.






34. Sewers are surcharged when the supply of water to be carried is greater than the capacity of the pipes to carry the flow. The surface of the wastewater in manholes rises above the top of the sewer pipe - and the sewer is under pressure or a head - ra






35. Horizontal shoring members - usually square - rough cut timber - that are used to hold solid sheeting - braces or vertical shoring members in place. Also called STRINGERS.






36. Downstream opening or discharge end of a pipe - culvert - or canal.






37. A branch of biology dealing with the relationship between living things and their environment.






38. The angle between a horizontal line andthe slope or surface of unsupported material such as gravel - sand -or loose soil. Also called the 'natural slope.'






39. Load applied along or parallel to and concentric with the primary axis






40. A plan for conserving or protecting various natural or manufactured resources. Such a plan is used as a management tool in making decisions regarding soil - water - vegetation - manufactured objects and other resources at a particular site.






41. In landscape architecture - an essential sheet showing site boundaries and significant site features - used as a basis for subsequent plan development.

43. An authorization issued by a government agency allowing construction of a project according to approved plans and specifications.






44. A tank used to store a chemical solution of known concentration for feed to a chemical feeder. A day tank usually stores sufficient chemical solution to properly treat the water being treated for at least one day. Also called an AGE TANK.
