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 conservation group that maintains a revolving fund for quickly buying land that is in danger of being developed inappropriately or without regard to proper environmental considerations.






2. The change to an area's natural resources - including animal and plant life - resulting from use by man. Some projects may require conducting of an 'environmental impact study' before development can proceed.






3. Rain and snow water accumulated in the earth's porous rock.






4. That part of rain or other precipitation that runs off the surface of a drainage area and does not enter the soil or the sewer system as inflow.






5. Any method of determining the weight a compacted material is able to support without damage or displacement. Usually stated in pounds per square foot.






6. British thermal units; the quantity of thermal energy required to raise one pound of water at its maximum density - 1 degree F. One BTU is equivalent to .293 watt hours - or 252 calories. One kilowatt hour is equivalent to 3412 BTU Back Pressure (wat






7. The condition of water or soil which contains a sufficient amount of acid substances to lower the pH below 7.0.






8. 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






9. The amount of runoff that reaches the point of measurement within a relatively short period of time after the occurrence of a storm or other form of precipitation. Also called 'direct runoff.'






10. The force that resists the separation of two bodies in contact.






11. A break in a lateral pipe somewhere between the sewer main and the building connection.






12. 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.






13. Broken stones - boulders - or other materials placed compactly or irregularly on levees or dikes for the protection of earth surfaces against the erosive action of waves.






14. Railing support at landings or other breaks in the stairs. If an angle post projects beyond the bottom of the strings - the ornamental detail formed at the bottom of the post is called the drop.






15. The process of adding air to water. Air can be added to water by either passing air through water or passing water through air. In wastewater treatment - air is added to freshen wastewater and to keep solids in suspension. With mixtures of wastewater






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






17. Narrowly defined - an extended view or prospect from a site which - many times - is as important as or more important than the site itself.






18. 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






19. Federal agency responsible for producing and managing many federally-funded public service programs - especially those affecting housing and public spaces.






20. A wastewater treatment process used to convert dissolved or suspended materials into a form more readily separated from the water being treated. Usually the process follows primary treatment by sedimentation. The process commonly is a type of biologi






21. The height to which something is elevated - such as the height above sea level.






22. The science and management of land - especially rural - agricultural land.






23. The protection - improvement and use of natural resources according to principles that will assure the highest economic or social benefits for people and the environment now and in the future.






24. A chamber or well used with storm or combined sewers as a means of removing grit which might otherwise enter and be deposited in sewers. Also see STORM WATER INLET and CURB INLET.






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






26. Material used to fill in a trench or excavation






27. A line from which heights and depths are calculated or measured. Also called a datum plane or a datum level.






28. The precipitation that cannot be absorbed by the soil and flows across the surface by gravity. The water that reaches a stream by traveling over the soil surface or falls directly into the stream channels - including not only the large permanent stre






29. A system of gutters - catch basins - yard drains - culverts and pipes for the purpose of conducting storm waters from an area - but intended to exclude domestic and industrial wastes.






30. A manhole located at the upstream end of a sewer and having no inlet pipe. Also called a DEADEND MANHOLE.






31. OE The pressure at a specific elevation exerted by a body of water at rest - or _ In the case of groundwater - the pressure at a specific elevation due to the weight of water at higher levels in the same zone of saturation.






32. An agency of the U.S. Department of Agriculture - primarily responsible for planning and overseeing the use of national forest lands by private - commercial and government users.






33. Landscape architecture - (civil) engineering - urban planning and architecture. Agronomy is also often included in this group.






34. A water treatment process in which solid particles settle out of the water being treated in a large clarifier or sedimentation basin.






35. Water or wastewater flowing from a higher elevation to a lower elevation due to the force of gravity. The water does not flow due to energy provided by a pump. Wherever possible - wastewater collection systems are designed to use the force of gravity






36. A relatively clear or forested area left untouched in or near a city. It may be active open space - such as a baseball field - or passive open space - such as an area of natural woodland.






37. Masonry composed of roughly shaped stones - well bonded and brought at irregular intervals vertically to discontinuous but approximately level beds or courses.






38. A sewer designed to carry both sanitary wastewaters and storm or surface water runoff.






39. A small box-like structure that contains valves used to regulate flows.






40. 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.'






41. The creative illustration - planning and specification of space for the greatest possible amount of harmony - utility - value and beauty.






42. The running off of water from a land surface or subsurface - such as through sewers or natural means.






43. In zoning - a housing or commercial development composed of individual units that are regulated as a whole.






44. The conversion of large solid particles of sludge into very fine particles which either dissolve or remain suspended in wastewater.






45. The illustration and description of problem-statements and large-scale design solutions that affect extensive areas of land; the anticipation of problems that will be encountered as human use and development of land continues.






46. 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.






47. The used household water and watercarried solids that flow in sewers to a wastewater treatment plant. The preferred term is WASTEWATER.






48. A groundwater table that is changed by artificial means. Examples of activities that artificially raise the level of a groundwater table include agricultural irrigation - dams and excessive sewer line exfiltration. A groundwater table can be artifici
