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

9710587 Serrano这是一个支持研究影响污染物在受污染含水层中流动和扩散的瞬时因素的作用的奖项。调查人员计划考虑在描述污染物扩散的数学表达式的公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，边界条件不可忽视，渗透系数的波动和正常受扩散的影响，特别是当它们与来自非点源的污染物从非饱和区的污染物渗透有关时。这一项目的结果可望增进我们对含水层中污染物大规模扩散的可变性的理解，这是由于许多条件现在不能被现有的数学公式所考虑。这一知识可直接应用于已受污染地下水净化系统的工程设计，也可用于考虑防止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. ***
