Presidential Young Investigator Awards

这是总统青年研究员奖。在堆填区，水渗入废物的速度对废物的分解速度有重大影响；因此，填埋盖的设计需要控制渗透速率。然而，盖层的水力特性目前还只是粗略的了解。在这项研究中，将调查覆盖系统的水力行为，并评估创新技术。将开发随机模型来模拟入渗过程。随机模型将在实际气候条件下通过大规模物理模型进行验证。

This is a Presidential Young Investigator Award. The rate at which water infiltrates waste in a landfill has a significant impact on the rate of decomposition; hence, landfill covers need to be designed to yield controlled rates of infiltration. The hydraulic behavior of covers, however, is at the present time only crudely understood. In this research, the hydraulic behavior of cover systems will be investigated and innovative technologies will be evaluated. Stochastic models will be developed to simulate the infiltration process. The stochastic models will be validated by large scale physical models tested under actual climatological conditions.
