Simulation of CO2 storage in geological formations inherently involves decisions concerning relevant physics, upscaling, and numerical modeling. We propose a benchmark study designed to assess the impact of these necessary choices, within the context of storage in a conceptually simple geological formation. The benchmark asks for answers to relevant questions regarding the ultimate fate of the ...
The Impact of Geological Units on the Groundwaters Quality of Hastijan, Southeastern of Delijan,Iran
This study was conducted to evaluate the quality of the groundwaters and the impact of geological units on these waters in Hastijan area. For this purpose, 11 samples of water resources have been collected with their appropriate dispersal. Physico-chemical parameters of Mn, Ni, Cd, Cu, Zn, As Fe, Cr, and ions K+, Na+,Ca2+, Mg2+, Cl-, So42-, Hco3- as well as indicators TH, TDS, EC, PH were deter...
this research was conducted in two protect and destroy region in the middle zagros, in illam province. in order to identification of ecological species group and evaluate density of regeneration, effect of many factors such as protection, vegetation, physiographic factors, physical and chemical properties of soil in study locations were studied. to achieve these purpose number of 54 plots using...
In this paper we examine ways to predict the distribution of siliceous rock in Europe, using a Bayesian technique known as ‘Weights-of-Evidence’. We use the technique to classify bedrock geological formations in terms of their likelihood of yielding tool-quality lithic raw materials, and we use the results to reexamine possible causes of a west–east cline in maximum lithic raw material transfer...
It is widely known that the development of gullies causes the loss of a great amount of soil and can be considered as one of the principal causes of geo-environmental degradation. The study area of the present research is located in the eastern shores of Urmia Lake. This study sought to evaluate the rate of growth and effective factors on the area’s gully dynamic over a year. To achieve th...
introduction suitability of groundwater for drinking, irrigation and industrial purposes depends upon its quality. changes in groundwater quality are due to variation in climatic conditions, residence time of water with aquifer materials and inputs from soil during percolation of water. multivariate statistical methods are one of the common and important methods for hydro geochemistry study. sa...
The option of capturing CO2 at large power stations and storing it in geological formations allows for the use of fossil energy resources without further destabilization of the climate system. From an economic point of view, the efficiency of Carbon Capturing and Sequestration (CCS) depends mainly on leakage rates, marginal costs of CCS (including the energy penalty) and the volume of available...
In this paper, we discuss and critique existing hypotheses about the geology of Middle-earth in light of current geological theories of planetary formation, mountain building (orogeny) and plate tectonics. We dispute the prevailing tectonic explanation for the major geological features of Middle-earth and Arda on the basis of evidence as yet not fully considered about the formation of the plane...
Investigation and analysis of groundwater quality to monitor contamination and identify the most important pollutants and pollution points is one of the research fields. The objective of this research was to plan to improve groundwater quality on various spatial and temporal scales. Groundwater information of Maragheh-Bonab plain was collected from 26 wells in 10 years (2001-2011) with 454 samp...
Injection of CO2 in geological formations has been proposed as an effective strategy to reduce the emissions of greenhouse gases. The understanding of interactions and the design of operations at an aquifer scale require the use computationally intensive numerical simulations. These simulations require the specification of flow and transport parameters of the formation that in general are poorl...
