NAME:__________________________________ CE4-L QUIZ NO. 3 I. IDENTIFICATION. Fill in the blanks. ________________1. Exists when controlling features are situated in a short length of channel. ________________2. The stage-discharge relation is governed by the slope, size, and roughness of the channel over a considerable distance. ________________3. USGS stands for? ________________4. It is used to obtain a record of flood crests at sites where recording gages are not installed. ________________5. Are installed to secure data for a project investigation, special studies or research. ________________6. Is a graph of stage of discharge versus time. ________________7. Also called hydrological year, discharge year or flow year. ________________8. The volume of water that flows past a certain point in a stream over a specific period of time. ________________9. Discharge formula. ________________10. It is commonly known as the price-type current meter. ________________11. It is used only for measuring shallow streams with a wading rod. ________________12. It is also known as discharge. ________________13. It is a method that measures the time that it takes the object to float a specified distance downstream. ________________14. A flow in which particles move in any direction at any time. ________________15. Flow in one direction with little to no mixing. ________________16. A calibrated scale which is used to provide a visual indication of liquid level. ________________17. A weight is lower from a bridge or other structure until it reaches the water surface. ________________18. An electromechanical device that records an electrical or mechanical input. ________________19. Records the pressure required to maintain small flow of gas from an orifice submerged in stream. ________________20. It is also known as stream flow changes.
