英文摘要	Pacific Northwest Laboratory (PNL) and Westinghouse Hanford Company (Westinghouse Hanford) are working together to develop for the US Department of Energy (DOE) protective barriers for the near-surface disposal of hazardous waste at the Hanford Site. The proposed barrier design consists of a layer of fine-textured soil overlying a series of layers grading from sand to basalt riprap. A multiyear research program is being conducted to assess the long-term performance of barrier configurations in restricting plants, animals, and water from contacting buried wastes. The purpose of this report is to review work done up to July 31 in FY 1990 on the evapotranspiration subtask of the water infiltration task. As stated in the test plan, specific objectives of PNL's evapotranspiration work were to (1) develop and test an environmentally controlled whole-plant gas exchange system, (2) collect evapotranspiration data at the whole-plant level on the small-tube lysimeters, (3) collect transpiration data on the shrubs at McGee Ranch, (4) collect data necessary to parameterize the plant component of the UNSAT-H code.
