Delineating baseflow contribution areas for streams – A model and methods comparison
Abstract This study addresses the delineation of areas that contribute baseflow to a stream reach, also known as stream capture zones. Such areas can be delineated using standard well capture zone delineation methods, with three important...

PM10 Dispersion Modeling by Means of CFD 3D and Eulerian–Lagrangian Models: Analysis and Comparison with Experiments
Abstract This research deals with the analysis of the dispersion of PM10 by using fluid-dynamic simulation framework. Firstly, an experimental campaign was made in a wind tunnel. A cylindrical emitter of PM10 was characterized in terms of PM10 mass...

Quantification of Fluid Migration Via faults Requires two-way Coupled Hydromechanical Simulations
Abstract Subsurface storage of fluids triggers pressure and volume changes in reservoirs, caprocks and faults. In this context, hydraulic fault conductivity can increase by several orders of magnitude, promoting upward migration of reservoir fluids...

The nonlinear nature of barotropic currents in oceans
Abstract The structure of the barotropic component of oceanic currents is discussed. First, we present observational evidence against the absence of the vertical shear of horizontal velocity in barotropic flows. We then discuss the Taylor-Proudman...

Secular change in lifetime of granitic crust and the continental growth: a new view from detrital zircon ages of sandstones
Abstract U-Pb ages of detrital zircons were newly dated for 4 Archean sandstones from the Pilbara craton in Australia, Wyoming craton in North America, and Kaapvaal craton in Africa. By using the present results with previously published data, we...

A large eddy simulation of flows around an underwater vehicle model using an immersed boundary method
Abstract A large eddy simulation (LES) of the flows around an underwater vehicle model at intermediate Reynolds numbers is performed. The underwater vehicle model is taken as the DARPA SUBOFF with full appendages, where the Reynolds number based on...

Methane in shallow subsurface sediments at the landward limit of the gas hydrate stability zone offshore western Svalbard
Abstract Offshore western Svalbard plumes of gas bubbles rise from the seafloor at the landward limit of the gas hydrate stability zone (LLGHSZ; ∼400m water depth). It is hypothesized that this methane may, in part, come from dissociation of gas...

A staggered overset grid method for resolved simulation of incompressible flow around moving spheres
Abstract An overset grid method for resolved simulation of incompressible (turbulent) flows around moving spherical particles is presented. The Navier–Stokes equations in spherical coordinates are solved on body-fitted spherical polar grids attached ...

An assessment of coal pillar system stability criteria based on a mechanistic evaluation of the interaction between coal pillars and the overburden
Abstract Coal pillar design has historically assigned a factor of safety (FoS) or stability factor (SF) according to their estimated strength and the assumed overburden load acting on them. Acceptable FoS values have been assigned based on past...
