Numerical Modelling of Seawater Intrusion in Manukan Island's Aquifer
A numerical model SEAWAT-2000 was developed to investigate the current seawater intrusion status in the low lying area of Manukan Island. SEAWAT-2000 output indicated that there is about 1.4% of freshwater and seawater mixing ratio at sea level in low lying area of Manukan Island illustrates the seawater intrusion problem. Upconing process simulated by SEAWAT-2000 showed the current status of s...

چکیده: در این تحقیق، برخی خواص فیزیکی و مکانیکی لوبیا قرمز به-صورت تابعی از محتوی رطوبت بررسی شد. نتایج نشان داد که رطوبت بر خواص فیزیکی لوبیا قرمز شامل طول، عرض، ضخامت، قطر متوسط هندسی، قطر متوسط حسابی، سطح تصویر شده، حجم، چگالی توده، تخلخل، وزن هزار دانه و زاویه ی استقرار استاتیکی در سطح احتمال 1 درصد اثر معنی داری دارد. به طوری که با افزایش رطوبت از 54/7 به 12 درصد بر پایه خشک طول، عرض، ضخام...
15 صفحه اولModes of seawater intrusion during transgressions
Analytical methods and numerical experiments are used to study salinization of groundwater in response to sea level rise. The system that is studied involves a saturated porous medium with an inclined upper surface. The upper surface is progressively inundated during sea level rise to simulate transgression, the landward migration of the shoreline. Four "modes" of seawater intrusion are disting...
متن کاملFormal derivation of seawater intrusion models
In this paper, we consider the flow of fresh and saltwater in a saturated porous medium in order to describe the seawater intrusion. Starting from a formulation with constant densities respectively of fresh and of saltwater, whose velocity is proportional to the gradient of pressure (Darcy’s law), we consider the formal asymptotic shallow water limit as the ratio between the thickness and the h...
متن کاملNumerical Modeling of Seawater Intrusion in Coastal Aquifer Using Finite Volume Unstructured Mesh Method
Saltwater intrusion widely occurs in coastal areas. Therefore, dissolved salts are the most common contaminants in freshwater in coastal aquifers and this contamination arises from saltwater invasion, caused primarily by human activities due to heavy urbanization. For investigation of the methods of increasing storage of fresh ground water and prevention of seawater encroachment, predicting the...
