  1. Water Movements

  2. Laminar and Turbulent Flow

  3. Reynolds Number (Re)Laminar Re<2300Transient 2300<Re<4000Turbulent Re>4000

  4. Turbulence is significant in: • conduction of heat (eddy conduction) • diffusion of dissolved substances (eddy diffusion) • viscosity (eddy viscosity)

  5. Surface Waves

  6. Deep Water Wave

  7. Water Movement in a Surface Wave

  8. Shallow Water Waves

  9. Fetch

  10. Lake Thunderbird

  11. Whitecaps on Lake Michigan

  12. Langmuir Circulation

  13. Causes of Surface Currents • Wind • Change in atmospheric pressure • Horizontal density gradients • Influx of water

  14. Surface Currents in Lake Erie

  15. Rip Current in Lake Erie

  16. Currents in a Stratified Lake Layers remain stable if the shearing force between them is low; Richardson number (Ri) remains higher than 0.25.

  17. Coriolis Effect on water movement

  18. Thermal Bars

  19. Formation of a Seiche

  20. Bimodal Seiche

  21. Seiche on Lake Erie

  22. Seiche traces from different parts of Lake Huron

  23. Inflow and outflow in Galich Lake

  24. Lake Sam Reyburn, TX

  25. Richardson number = shearing force between layersFrom Fernandez and Imberger (2006)

  26. Table 7-1

  27. Movement of Water in a Stream Channel

  28. Run and Riffle

  29. Standing Wave in Stream

  30. Standing waves on the Colorado River in the Grand Canyon

  31. Discharge and Gage Height
