  1. Final Project From USGS Hydrologic Atlas online

  2. Conceptual Model of the flow system Recharge Recharge Playa

  3. Layers The problem of dry cells and re-saturation Layer 1 Datum Layer 2 50 ft gap represents confining bed Layer 3 – variable bottom

  4. from GWV Layer 1 = type 1 Layer 2, 3 = type 3

  5. Leakance between layers where each Layer belongs to a different hydrogeologic unit Layer 1 leakance See A&W, p. 81

  6. Leakance “Quasi 3D” model Layer 2 leakance See A&W, p. 81

  7. from GWV

  8. Conceptual Model of the flow system Recharge Recharge Playa

  9. QET = RETMxy [h - (hs-d)] / d ET for h  hs-d and h < hs RETM is the maximum ET rate, which occurs when h = hs. d extinction depth h hs

  10. QET = QETM at the land surface. QET = 0 below the extinction depth.

  11. Calibration Targets associated error calibration value 0.80 m 20.24 m Target with smaller associated error. Target with relatively large associated error.
