Predicted drainage at a semiarid site: Sensitivity to hydraulic property description and vapor flow
Conference
·
OSTI ID:6626952
At the US Department of Energy's Hanford Site in southcentral Washington State, the sensitivity of predicted drainage to soil hydraulic property description and vapor flow was tested. Ten representations of the hydraulic properties were obtained by selectively using the available retention data and varying the conductivity model. The retention data for each case were fit with the Brooks-Corey retention function, and hydraulic conductivity was generated with either the Burdine or Mualem conductivity models. The resultant functions were used to simulate the 1986 water balance of a nonvegetated lysimeter containing sand, using simulations of the 1985 water balance to establish initial conditions for each case. 13 refs., 8 figs., 2 tabs.
