Changes in global groundwater organic carbon driven by climate change and urbanization
Nature Communications, 2020 Climate change and urbanization can increase pressures on groundwater resources, but little is known about how groundwater quality will change. Here, we use a global synthesis (n = 9,404) to reveal the drivers of dissolved organic carbon (DOC), which is ...

Biofuels, Bioproducts and Biorefining, EarlyView.Abstract This study presents a novel treatment of biogas digestate to produce biochar at processing temperatures of 500–700 °C. The resulting biochar was applied for the simultaneous removal of methylene blue (MB) and malachite green (MG) in a binary system.

Multi-Agent System for Groundwater Depletion Using Game Theory [PDF]
arXiv, 2016 Groundwater is one of the most vital of all common pool resources throughout the world. More than half of groundwater is used to grow crops. This research models groundwater depletion patterns within a multi-agent system framework. Irrigators are modeled as agents in the multi-agent system.

Groundwater Entrepreneurs in China: Selling Water to Meet the Demand for Water [PDF]
, 2006 The overall goal of our paper is to better understand the development of groundwater markets in northern China. In particular, we focus on the factors that determine the development of groundwater markets in our attempt to explain their 'breadth' and ...

Gradual Variation Analysis for Groundwater Flow [PDF]
arXiv, 2010 Groundwater flow in Washington DC greatly influences the surface water quality in urban areas. The current methods of flow estimation, based on Darcy's Law and the groundwater flow equation, can be described by the diffusion equation (the transient flow) and the Laplace equation (the steady-state flow).

Invisible Labor and the “Ghost Particle”: Underground Physics at the Kolar Gold Fields**
Berichte zur Wissenschaftsgeschichte, EarlyView.Abstract When cosmic rays—high‐energy particles from outer space—encounter the Earth's atmosphere, they produce particles called neutrinos. To detect them, physicists go underground inside deep mines where the overlying rock can filter out the cosmic‐ray background radiation.

Inflow and Loadings from Ground Water to the Great Bay Estuary, New Hampshire [PDF]
, 2004 This final report presents the results of a study to evaluate groundwater inflow and nutrient loadings to the Great Bay Estuary, New Hampshire. The evaluation of inflow was accomplished independently by two methods: one, used thermal imagery, and the ...
