Finite element analysis of ground deformation due to dike intrusion with applications to Mt. Etna volcano
FEM ground deformation dike intrusion real medium
2015/9/15
A 2D finite elements study was carried out to analyse the effects caused by dike intrusion inside a heterogeneous medium and with a realistic topography of Mt. Etna volcano. Firstly, the method (dimen...
Remobilization of silicic intrusion by mafic magmas during the 2010 Eyjafjallajökull eruption
silicic intrusion mafic magmas 2010 Eyjafjallajokull eruption
2014/12/31
Injection of basaltic magmas into silicic crustal holding chambers and subsequent magma mingling or mixing is a process that has been recognised since the late seventies as resulting in explosive erup...
High Pressure Liquidus Studies of the Inferred Magma Composition of the Kiglapait Layered Intrusion, Labrador, Canada
High Pressure Liquidus Studies Inferred Magma Composition Kiglapait Layered Intrusion Labrador Canada
2014/10/22
The depth and nature of the source region of the Kiglapait Layered Intrusion, Labrador, Canada, were experimentally explored using rocks representing the troctolitic bulk composition of the intrusion....
The Theory and Application of Upwind Finite Difference Fractional Steps Procedure for Seawater Intrusion
Seawater Intrusion Three-Dimensional Region
2013/3/11
Numerical simulation and theoretical analysis of seawater intrusion is the mathematical basis for modern environmental science. Its mathematical model is the nonlinear coupled system of partial differ...
Tropospheric ozone variations at the Nepal Climate Observatory-Pyramid (Himalayas, 5079 m a.s.l.) and influence of deep stratospheric intrusion events
Tropospheric ozone the Nepal Climate Observatory-Pyramid deep stratospheric intrusion events
2010/8/16
The paper presents the first 2 years of continuous surface ozone (O3) observations and systematic assessment of the influence of stratospheric intrusions (SI) at the Nepal Climate Observatory at Pyram...
Finite Element Analysis of Controlled Saltwater Intrusion in Heterogeneous Reservoirs
Finite Element Analysis Saltwater Intrusion Heterogeneous Reservoirs
2009/10/27
Environmental cleaning operations in coastal areas by pumping are complicated
by the presence of both fresh water and salt water. The density difference
makes the flow conditions very complicated to...
GROUNDWATER EXTRACTION IN THE UNITED ARAB EMIRATES UNDER THE CONSTRAINT OF SALINE WATER INTRUSION

Fresh water flows counterbalance salinity intrusion in the coastal zone of Bangladesh. To quantify the required fresh water, requires a detailed understanding of physical phenomena including tidal mot...
Comparison of empirical models with intensively observed data for prediction of salt intrusion in the Sumjin River estuary, Korea
salt intrusion Sumjin River estuary
2009/7/22
Performance of empirical models has been compared with extensively observed data to determine the most suitable model for prediction of salt intrusion in the Sumjin River estuary, Korea. Intensive mea...
Field, Petrographic and Geochemical Characteristics of the Hamit Alkaline Intrusion in the Central Anatolian Crystalline Complex, Turkey
Hamit pluton Central Anatolian Crystalline Complex (CACC) syenite A-type granites post-collisional intrusives
2009/7/8
The Hamit pluton is one of the alkaline intrusions in the Central Anatolian Crystalline Complex (CACC). The pluton consists of nepheline syenite, pseudoleucite syenite, alkali-feldspar syenite and qua...
Salt intrusion in multi-channel estuaries：a case study in the Mekong Delta, Vietnam
multi-channel estuaries Mekong Delta Salt intrusion
2009/5/15
There is a well-tested theory for the computation of salt intrusion in alluvial estuaries that is fully analytical and predictive. The theory uses analytical equations to predict the mixing behaviour ...
The Three-Dimensional Mapping of a Small Thermohaline Intrusion
Three-Dimensional Mapping Small Thermohaline Intrusion Mixed-Layer Experiment
2009/2/18
During the Mixed-Layer Experiment (MILE) at Ocean Station P in August-September 1977. a depth-cycling towed CTD was used to map intrusions below the seasonal thermocline. In a 10 km square two promine...
In this paper a mechanism is proposed which could be responsible for the formation of sharp horizontal density gradients such as those observed in shallow seas, from fluid which initially has weak hor...
Salinity Intrusion in Estuaries
Estuaries Salinity Intrusion breadth variation depth variation
2009/2/10
One dimensional time-averaged solutions are examined for salinity intrusion in estuaries with a breadth variation BL(X/λ)n and a depth variation H(X/λ)m, where X is the distance from the head of the e...
Intrusion Characteristics in the Antarctic Polar Front
Intrusion Characteristics Antarctic Polar Front
2009/2/9
Data obtained on two cruises to the Antarctic Polar Front are used to investigate the nature of thermohaline intrusions in the front. These data, obtained in the Drake Passage and south of New Zealand...
