Mixing in confined stratified aquifers

open access: yesJournal of Contaminant Hydrology, 2011
Spatial variability in a flow field leads to spreading of a tracer plume. The effect of microdispersion is to smooth concentration gradients that exist in the system. The combined effect of these two phenomena leads to an 'effective' enhanced mixing that can be asymptotically quantified by an effective dispersion coefficient (i.e.

Soil Microbial Responses to Artificial CO2 Leakage in Controlled Field Experiments in South Korea

open access: yesGreenhouse Gases: Science and Technology, EarlyView.
ABSTRACT The potential environmental impacts of CO2 leakage from carbon capture and storage (CCS) sites remain a critical concern for the long‐term viability of CCS technologies. Soil microbial communities, which regulate essential biogeochemical processes, are particularly sensitive to changes in soil CO2 concentrations.

Adoption timing of water conserving irrigation practices in the Mississippi Delta: An application of duration analysis

open access: yesJournal of the Agricultural and Applied Economics Association, EarlyView.
Abstract Irrigation drives the decline in the Mississippi River Valley alluvial aquifer. Rapid adoption of water‐conserving practices (WCPs) is key. Duration analysis of the adoption of computerized (polypipe) hole selection (CHS) and center‐pivot (CP) irrigation in the Mississippi Delta shows that: NRCS funding for WCPs and crop acreage (cotton for CP

Dual process for improved recovery of essential oil and pectin from citrus waste

open access: yesJournal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND Citrus essential oils (EO), particularly orange essential oil (OEO) and pectin, are high‐value chemical products widely used across various industries, including pharmaceuticals, food and beverages, detergents, and cosmetics. These compounds are present in the residual by‐products generated by juice production industries, and their ...

Surface water irrigation reservoirs improve groundwater recovery in a heavily stressed aquifer

open access: yesJournal of Environmental Quality, EarlyView.
Abstract Expansion of irrigated cropland area in eastern Arkansas has led to the formation of regional cones of depression and creation of critical groundwater areas for the Mississippi River Valley alluvial aquifer (MRVA) in Arkansas. In response, use of surface water reservoirs for irrigation in the Grand Prairie critical groundwater area (GPCGA) has
