  2. I. Water Distribution 1.36 billion cubic km of water 97.2% oceans 2.15% glacial ice 0.65% lakes, streams, ground water

  3. II. The Hydrologic Cycle

  4. III. Stream Flow A. Terms

  5. III. Stream Flow • Terms 1. Laminar vs. Turbulent

  6. III. Stream Flow • Terms 1. Laminar vs. Turbulent

  7. III. Stream Flow • Terms 2. Velocity, Area, Discharge

  8. III. Stream Flow Discharge = Velocity x Area Q = V x A

  9. III. Stream Flow • Terms 3. Gradient

  10. III. Stream Flow • Terms 3. Gradient Rise = Vertical drop of the stream Run Horizontal Distance

  11. Rise = Vertical drop of the stream Run Horizontal Distance

  12. III. Stream Flow B. Downstream Trends 1. gradient 2. width and depth 3. discharge 4. velocity

  17. III. Work of Running Water A. Erosion

  18. III. Work of Running Water 1) Sheet flow A. Erosion

  19. III. Work of Running Water 1) Sheet flow 2) Rill flow A. Erosion

  20. 3) Gully flow

  21. III. Work of Running Water B. Transportation 1) dissolved load
