Due to heterogeneity of lands over ungauged/sparsely gauged watersheds at which the hydrological flows occur, there is a need to upscale the hydrological conservation equations to the scale of the grid areas of the numerical mesh laid out over the watershed which is being modelled. A literature review of the various methods utilized in hydrology for the upscaling of hydrological conservation eq...

In this paper, a mathematical model of multiphase filtration in deformable porous medium is presented. Based on the proposed model, influence deformation processes studied. Numerical calculations are performed and characteristics process determined. This paper shows that an increase compressibility coefficient leads to sharp decrease porosity, absolute permeability internal pressure near well, ...

The cover-management factor (C-factor) is important for studying soil erosion. In addition, it is important to use sampling plot data to estimate the regional C-factor when assessing erosion and soil conservation. Here, the loess hill and gully region in Ansai County, China, was studied to determine a method for computing the C-factor. This C-factor is used in the Universal Soil Loss Equation (...

Stochastic reservoir models must honor as much input data as possible to be reliable numerical models of the reservoir under study. Traditional simulation algorithms are unable to honor either complex geological/morphological patterns or engineering data from well tests. The technique developed in this dissertation may be used to incorporate such information into stochastic reservoir models. Th...

Gas hydrates (GH) are well known to have an influential effect on the velocity and attenuation of gas hydrate-bearing sediments (GHBS). Based rock physics modeling, sediment has been extensively used characterize distribution hydrate. However, results obtained from different models show a significant variation. In this study, we firstly review compare existing modeling for attenuation. The assu...

Intervention to enhance wellbeing through participation in the creative arts has a transformative potential, but the spatialities to this are poorly theorised. The paper examines arts-based interventions in two primary schools in which small groups of children are taken out of their everyday classrooms to participate in weekly sessions. The paper argues that such intervention is usefully seen a...

This study introduces PoreFlow, a pore-network modeling tool capable of simulating fluid flow and multi-component reactive and adsorptive transport under saturated and variably saturated conditions. PoreFlow includes a variety of modules, such as: pore network generator, drainage simulator, calculation of pressure and velocity distributions, and modeling of reactive solute transport accounting ...

accurate permeability estimation has always been a concern in determining flow units, assigning appropriate capillary pressure andrelative permeability curves to reservoir rock types, geological modeling, and dynamic simulation.acoustic method can be used as analternative and effective tool for permeability determination. in this study, a four-step approach is proposed for permeability estimati...
