The Hydrology of Dispersion in Regional Aquifers: The Influence of Transient Boundary Conditions and Recharge

9710587塞拉诺这是一个奖项，以支持对影响污染物在受污染含水层中流动和扩散的瞬态因素的作用进行研究。 研究者计划考虑在描述污染物扩散的数学表达式中通常被排除的因素。 将考虑的因素包括假设地层受到补给，地下水位不稳定，边界条件不可忽略，波动以及正常的水力传导率受到分散的影响，特别是当它们与非点源污染物从非饱和带渗透饱和时。 这个项目的结果，预计将提高我们的理解的变化，大规模的污染物分散在含水层归因于许多条件下，现在不能被认为是由现有的数学公式。 这方面的知识可以直接应用于工程设计的系统，净化已被污染的地下水，也可能有适用性，以考虑防止污染的非点源污染物对含水层的污染。 ***

9710587 Serrano This is an award to support research on the role of transient factors that affect the flow and dispersion of contaminants in contaminated aquifers. The investigator plans to consider factors that are normally excluded in formulation of mathematical expressions to describe contaminant dispersion. The factors that will be considered include assumption that the formation is subjected to recharge, the water table is unstable, boundary conditions are not negligible and fluctuations as well as normality of hydraulic conductivity are affected by dispersion especially as they relate to contaminant penetration of the saturated from the unsaturated zone by contaminants from non point sources. Results of this project are expected to improve our understanding of the variability of large-scale contaminant dispersion in aquifers attributable to many conditions not now capable of being considered by existing mathematical formulations. This knowledge may be directly applied to engineering design of systems for decontamination of groundwater already contaminated and may also have applicability to considering prevention of the pollution of aquifers by contaminants from nonpoint sources. ***
