Quasi-steady exchange flow in the bosphorus

Gregg, MC
Ozsoy, E
Latif, MA
Current meter moorings and high-resolution surveys in the Bosphorus reveal important details of the exchange flow. During early September 1994, the flow was quasi-steady and demonstrated strong mixing, particularly in the surface layer after it entered the principal contraction of the strait. Composite Froude numbers in the contraction are lower than expected, consistent with recent modeling that shows friction producing significant deviations from predictions of inviscid two-layer hydraulic theory.


Numerical model development for Güzelyurt aquifer, North Cyprus
Demir, Cansu; Ünlü, Kahraman; Akıntuğ, Bertuğ; Department of Environmental Engineering (2018)
Güzelyurt, coastal aquifer, which is an unconfined, is the most important, at the same time the largest drinking, municipal, and irrigational water resource in Turkish Republic of Northern Cyprus (TRNC). However, the aquifer has exceeded its safe yield capacity due to excessive and uncontrolled pumping over the years and the water quality has been seriously degraded due to seawater intrusion. The “TRNC Water Supply Project”, completed in June 2016, will annually supply about 75 MCM of water via pipeline und...
Frequency dependence of the constitutive parameters of causal perfectly matched anisotropic absorbers
Kuzuoğlu, Mustafa (1996-12-01)
Perfectly matched layers (PML's), which are employed for mesh truncation in the finite-difference time-domain (FDTD) or in finite element methods (FEM's), can be realized by artificial anisotropic materials with properly chosen permittivity and permeability tensors. The tensor constitutive parameters must satisfy the Kramers-Kronig relationships, so that the law of causality holds. These relations are used to relate the real and imaginary parts of the constitutive parameters of the PML media to deduce the a...
Application of a three-dimensional numerical model to the idealized conditions of the bosphorus strait.
Sözer, Adil; Özsoy, Emin; Department of Marine Sciences (2002)
The Bosphorus Strait is a narrow and shallow channel between the Sea of Marmara and the Black Sea which plays an important role in the Turkish Straits System connecting the Black Sea and the Mediterranean Sea. The exchange flow through the Bosphorus Strait is principally determined by geometry and stratification, and exhibits a complex nonlinear response to forcing by the net water budget, pressure and wind setup effects in adjacent basins. This study aims for a better understanding of the behaviour of the ...
Optimal management of coastal aquifers using heuristic algorithms
Demirbaş, Korkut; Altan Sakarya, Ayşe Burcu; Önder, Halil; Department of Civil Engineering (2011)
Excessive pumping in coastal aquifers results in seawater intrusion where optimal and efficient planning is essential. In this study, numerical solution of single potential solution by Strack is combined with genetic algorithm (GA) to find the maximum extraction amount in a coastal aquifer. Seawater intrusion is tracked with the potential value at the extraction well locations. A code is developed by combining GA and a subroutine repeatedly calling MODFLOW as a numerical solver to calculate the potential di...
Threshold Optimization for Tracking a Nonmaneuvering Target
Aslan, Murat Samil; Saranlı, Afşar (2011-10-01)
A promising line of research attempts to bridge the gap between radar detector and radar tracker by means of considering jointly optimal parameter settings for both of these subsystems. We consider the problem of detection threshold optimization in a tracker-aware manner so that a feedback from the tracker to the detector is formed to maximize the overall system performance. We explore the research space for tracker-aware detector threshold optimization schemes and compare various approaches in a theoretica...
