1. Apron – a platform to reveive the water flowing over a dam.
2. Archimedes Principle - an object is immersed in a fluid is buoyed up by a force equal to the weight of the fluid displaced by the object.
3. Bernoulli’s Equation – P+12ρV2+ρgh=constant (where P-pressure, ρ–density, V-velocity)
4. Break water - are structures constructed on coasts as part of coastal defense or to protect an anchorage from the effects of both weather and long shore drift.
5. Chezy’s Equation - V= c (R S)1/2 (where V-velocity, c- conduit coefficient, r- hydraulic radius of the conduit, s-slope of the conduit)
6. Chlorination - the process of adding the element chlorine to water as a method of water purification to make it fit for human consumption as drinking water.
7. Coefficient of contraction - the ratio of the cross-sectional area of the first vena contracta to the area of the discharge aperture.
8. Coefficient of discharge - is the ratio of the actual discharge to the theoretical discharge.
9. Coefficient of velocity - the ratio of the actual velocity to the theoretical velocity of a fluid jet
10. Combined shear –
11. Continuous flow – uninterrupted flow of a fluid.
12. Critical depth - is the depth of flow (for a given discharge) where the specific energy is at a minimum.
13. Critical flow - This condition exists when at a fixed upstream pressure the flow cannot be further increased by lowering the downstream pressure.
14. Culverts - is a drain or pipe that allows water to flow under a road, railroad, trail, or similar obstruction
15. Darcy-Weisbach Equation - hf= fDLDV22g (where hf – headloss, fD - Darcy-Weisbach friction factor, L – pipe length, D – pipe diameter, V-velocity, g – gravity)
16. Datum - is a reference level surface that has a constant elevation over a large geographical area
17. Dike - a natural or artificial slope or wall to regulate water levels.
18. Discharge – the volume rate of flow of a...
