Evaluating the Effects of Organic vs. Conventional Farming on Aquifer Water Quality [PDF]

open access: yesarXiv
This study analyzes water quality dynamics and aquifer recharge through irrigated agriculture, contributing to the literature on Managed Aquifer Recharge (MAR) amidst growing water scarcity. We develop two optimal control models-- a linear and a non-linear extension of (Martin and Stahn, 2013) --that incorporate the impact of fertilizers on aquifer ...

Jacobian-Free Newton-Krylov with a globalization method for solving groundwater flow models of multi-layer aquifer systems [PDF]

open access: yesarXiv
A Jacobian free Newton Krylov (JFNK) method with a globalization scheme is introduced to solve large and complex nonlinear systems of equations that arise in groundwater flow models of multi-layer aquifer systems. We explore the advantages of the JFNK method relative to the Newton-Krylov (NK) method and identify the circumstances in which the JFNK ...
