Abstract: Vadose zone well (VZW) injection is an effective method of managed aquifer recharge (MAR), and it plays an important role in semiarid and arid regions. Accurate estimation of the recharge of VZW injection remains a challenge ...

Abstract: Heterogeneously layered river-basin or reservoir-bank aquifers are widely distributed, and the two-layer aquifer system is a simple representative of such aquifers. In this research, a conceptual model of vertical groundwater ...

Abstract: The writers have formulated quasi-analytical nonlinear solutions to investigate the uncertainty of one-dimensional ground-water flow in heterogeneous formations in which the standard deviation of the log hydraulic conductivity σ

Abstract: A falaj (plural aflaj) (also called qanat) is a unique type of near-horizontal well that extracts groundwater by gravity. Wadi aquifers, usually bounded by lateral no-flow boundaries, are a vital source of water supply in ...

Abstract: An exact solution for transient Forchheimer flow to a well does not currently exist. However, this paper presents a set of approximate solutions, which can be used as a framework for verifying future numerical models that ...

Abstract: This study uses the mobile-immobile model (MIM) and the traditional convection-dispersion equation (CDE) to analyze the observed breakthrough curves (BTCs) at different distances in a 1,250-cm-long saturated and highly ...

Abstract: Air entrapment in soil is common in cases of farmland flood irrigation or intense rain. A simple, physically based model would be more useful than the complex two-phase (gaseous and liquid phase) flow model to describe ...

Abstract: An investigation of a groundwater system often requires the prediction of the spatiotemporal distribution of groundwater heads, which determine the groundwater flow direction and magnitude, among other applications. How ...
