Understanding the Hydrologic Cycle: Precipitation, Runoff, and Streamflow, Slides of Human Resource Management
Explore the hydrologic cycle, a vital process that summarizes earth's water circulation. Learn about precipitation, infiltration, runoff, and streamflow, including factors that influence velocity, discharge, and profile. Understand sources of earth's water and the impact of terrain and vegetation on sheetflow.

The hydrologic cycle
Running water
Begins as sheetflow
Infiltration capacity is controlled by
Intensity and duration of rainfall
Prior wetted condition of the soil - Soil texture - Slope of the land - Nature of the vegetative cover Sheetflow develops into tiny channelscalled rills
Running water
Streamflow
Two types of flow determined primarilyby velocity
Laminar flow
Turbulent flow Factors that determine velocity
Gradient, or slope
Channel characteristics including shape, size,and roughness
Running water
Changes from upstream to downstream
Profile
Profile is a smooth curve
Gradient decreases downstream Factors that increase downstream
Velocity
Discharge - Channel size
Longitudinal profile
of a stream
Running water
Base level and graded streams
Two general types of base level
Ultimate (sea level)
Local or temporary Changing conditions causes readjustmentof stream activities
Raising base level causes deposition
Lowering base level causes erosion
