The Effect of Regional Hydrologic and Hydraulic Parameters on Macrodispersion in Heterogeneous Aquifers

这是一个奖项，旨在为地下水污染物从其源头到感兴趣的地点的移动建模研究提供支持。该项目是根据NSF第89-21004号补助金进行的对研究的重新支持，其中，调查者重点介绍了模拟地下水流和非点源溶质的基本方法。在这个重建项目中，调查员计划对模型进行改进，并进行现场实验，以验证其对污染物在地下水含水层。这一项目预计将提高我们对区域水文特征和含水层参数对速率的影响的基本理解。污染物在含水层中的移动速度。调查者计划将开发的模型的分散参数与易于测量的变量相关联，例如含水层补给率，水力坡度、导水率、含水层厚度和实验室尺度由实验室尺度的分散性确定。预计结果将用于预测影响地下水污染的规模相关因素，以及危险废物容器设施的设计和测试以及实施土壤和环境污染的补救行动含水层。

This is an award to provide support for research on modeling of the movement of groundwater pollutants from their source to a location of interest. This project is a renewal of support for research, conducted under NSF Grant No. 89- 21004, in which the investigator focussed on fundamental methodology for modeling groundwater flow and solutes that are derived from non- point sources. In this renewal project, the investigator plans on improvement of the model and conducting field experiments to verify its predictive ability for movement of pollutants in groundwater aquifers. This project is expected to improve our fundamental understanding of the effect that regional hydrological characteristics and aquifer parameters have on the rate at which pollutants move in aquifers. The investigator plans on relating the dispersion parameters of the developed models to easily measurable variables such as the rate of aquifer recharge, the hydraulic gradient, transmissivity, aquifer thickness and laboratory-scale determined in laboratory-scale dispersivity. Results are expected to be utilized in forecasting of scale-dependent factors influencing groundwater pollution, and in the design and test of hazardous waste containment facilities and in implementation of remedial actions for decontamination of soil and aquifers.
