Preferential and Non-Darcy Flows in the Hyporheic Zone: Surface Water-Groundwater Hydraulics and Effects on Stream Functions
Surface water-groundwater interaction can provide various stream functions including temperature regulation, nutrient cycling, pollutant attenuation, and habitat creation. However previous literature is divided on the extent and conditions of these benefits. This dissertation has explored the …

Surface Water and Groundwater Hydraulics, Exchange, and Transport During Simulated Overbank Floods Along a Third-Order Stream in Southwest Virginia
… yet rigorous field evaluations of surface and groundwater flows during overbank floods are rare. We conducted five sets of experimental floods to mimic floodplain reconnection. Experimental floods entailed pumping stream water onto an existing floodplain swale, and were conducted throughout the …

Base Flow Recession Analysis for Streamflow and Spring Flow
… streams dominate the flowing streams and groundwater hydraulics governs the recession behavior. The ephemeral stream densities vary from arid regions to humid regions. Therefore, the characteristics of transition flow across the climate gradients are also tested in 40 watersheds. It is …

In Situ Oxidation of 1,4-Dioxane with Persulfate-Based Oxidation Activated by Iron Minerals
Groundwater contaminant plumes of 1,4-dioxane (dioxane) and its co-contaminants (chlorinated solvents) have been found at many hazardous waste sites. There is increasing attention paid to the persulfate-based activation method for in situ degradation of organic contaminants due to its high …

ΑΣΤΑΘΗΣ ΡΟΗ ΣΕ ΚΑΡΣΤΙΚΑ ΥΔΡΟΦΟΡΑ ΣΤΡΩΜΑΤΑ ΜΕ ΤΗ ΜΕΘΟΔΟ ΤΩΝ ΠΕΠΕΡΑΣΜΕΝΩΝ ΣΤΟΙΧΕΙΩΝ
THE GROUNDWATER FLOW IN A CONFINED KARST AQUIFER IS STUDIED BY THE MODEL OF DOUBLE POROSITY. THIS IS A CONTINUOUS MODEL BUT IT TAKES INTO ACCOUNT THE HETEROGENEITY OF POROUS MEDIA. IT IS ALSO ASSUMED THAT IN KARST AQUIFERS THE FLOW CAN BE BEYOND THE UPPER LIMIT OF THE VALIDITY OF DARCY'S LAW. THE …
