Integrated Rapid Hydrogeologic Approach to Delineate Areas Affected by Advective Transport in Mantled Karst, With An Application to Clear Creek Basin, Washington County, Arkansas

摘要

The main objectives of this study are 1) to integrate an understanding of flow and transport in mantled karst settings and 2) to develop a simple model that would predict possible advective routes of travel in a mantled karst in an economical, timely manner. The scope was narrowed to exclude time-of-travel, diffusion, dispersion, and sorption. The scope of this project is focused. First, it deals only with advective transport. It does not consider concentration variations - nor does it consider temporal or transient factors. Results are intended to show specific areas at risk, not time-of-travel, nor any time of contamination. Because flow in karst is typically rapid, this study considers worst-case scenarios. Attenuation mechanisms, including sorption and biodegradation are not considered in this model.
