Presentation Transcript


NWS Calibration Workshop, LMRFC March, 2009 slide - 1


Goals

Unbiased reproduction of historical conditions

Parameters that cause model components to mimic the hydrologic processes they were designed to represent

Ability to extrapolate beyond conditions encountered in the historical record

Strategy

Must account for the physics of the model and how each portion of the hydrograph was intended to be modeled

Must understand the structure of the model

Sacramento Model - Percolation

  • Function of two forces:

  • Lower Zone Dryness (Capillary Suction Force)

  • Lower Zone Deficiency Ratio (LZDEFR)

  • Upper Zone Free Water Wetness (Gravity Force)

here?

When is

percolation at

the max rate?
