Seawater Intrusion Risk and Prevention Technology of Coastal and Large-Span Underground Oil Storage Cavern

Energies, 2022
The presence of a high concentration of Cl− in saltwater will erode the structure and facilities, reducing the stability and service life of the underground oil storage cavern.

Derivation of Seawater Intrusion Models by Formal Asymptotics [PDF]

SIAM Journal on Applied Mathematics, 2014
In this paper, we consider the flow of fresh- and saltwater in a saturated porous medium in order to describe the process of seawater intrusion. Starting from a formulation with constant densities of fresh- and saltwater, whose velocities are proportional to the gradient of pressure (Darcy's law), we consider the formal asymptotic limit as the aspect ...

Layered seawater intrusion and melt under grounded ice [PDF]

The Cryosphere, 2022
Increasing melt of ice sheets at their floating or vertical interfaces with the ocean is a major driver of marine ice sheet retreat and sea level rise. However, the extent to which warm, salty seawater may drive melting under the grounded portions of ice

Vertical average for modeling seawater intrusion [PDF]

Water Resources Research, 2011
Seawater intrusion in coastal aquifers is a 3‐D phenomenon. However, 3‐D regional aquifer models are often limited by insufficient geological and hydrological data, the large horizontal to vertical scales ratio, and by numerical constraints. We present an effective formulation for modeling seawater intrusion that relies on a dimensional reduction of ...

The democratic growth advantage revisited: disentangling global trends from domestic political effects in the United States economy

Frontiers in Political Science
The relationship between party politics and economic performance is a fundamental aspect of political economy. Although the “Democratic growth advantage” in the United States has garnered significant attention, previous studies often fail to account for ...

Spatial distribution and risk assessment of microplastics in surface sediments in semi-enclosed waters: a case study of Laizhou Bay

Frontiers in Marine Science
Marine ecosystems are the most important sinks for microplastics (MPs) from inland sources, and the input of large quantities of MPs into the oceans poses a serious threat to marine organisms and ecosystems.

Carbonate aquifers in Apulia and seawater intrusion

, 2005
he predisposing factors and the determining factors of seawater intrusion in wide carbonate aquifers of Apulia ( Southern Italy) are characterized. Main predisposing factors prove the sedimentation environment, the tectonic-karstic evolution, the geometry of the aquifers in relation to the coastline, the depth of the aquifers, the existence of ...

Identification of the Distribution of Seawater Intrusion Using the Resistivity 2D Method in the Belawan Area, North Sumatra Province

Jurnal Ilmu Lingkungan
Excessive withdrawal of deep groundwater has an impact on changing the direction of groundwater flow so that the hydrostatic pressure decreases, resulting in seawater intrusion.
