Water Cycle

• Components of a system include inputs, throughputs, outputs, stores/components, flows/transfers, and processes
• Over time, a system may change to another system and reach a new dynamic equilibrium
• Systems Approach: An approach to studying complex phenomena by analyzing the interactions and interdependencies between various components or parts of a system.
• Name one of the different flows of the water cycle?

  Infiltration

  Percolation

  Throughflow Surface Run off (overland flow)

  Ground Water flow

  Stream Flow

  Storm Flow
• What is the definition of interception?

  Water which is stored in the vegetation
• What are the three main compoenets of interception?

  1. interception loss
  2. throughfall
  3. stem fall
• How much water do configerious forests intercept?

  25%- 30%
• How much water do deciduous forests intercept?

  10%- 15%
• Wind decreases interception more in the summer then in the winter
• Define Infiltration: the process which water soaks into and is absorbed by soil particles
• What is the definition of infiltration capacity?

  The maximum rate at which rain can be absorbed by soil in a "given condition"
