Development of a numerical 2-dimensional beach evolution model

This paper presents the description of a 2-dimensional numerical model constructed for the simulation of beach evolution under the action of wind waves only over the arbitrary land and sea topographies around existing coastal structures and formations. The developed beach evolution numerical model is composed of 4 submodels: a nearshore spectral wave transformation model based on an energy balance equation including random wave breaking and diffraction terms to compute the nearshore wave characteristics, a nearshore wave-induced circulation model based on the nonlinear shallow water equations to compute the nearshore depth-averaged wave-induced current velocities and mean water level changes, a sediment transport model to compute the local total sediment transport rates occurring under the action of wind waves, and a bottom evolution model to compute the bed level changes in time based on the gradients of sediment transport rates in cross-shore and longshore directions. The developed models are applied successfully to the SANDYDUCK field experiments and to some conceptual benchmark cases including simulation of rip currents around beach cusps, beach evolution around a single shore perpendicular groin, and a series of offshore breakwaters. The numerical model gave results in agreement with the measurements both qualitatively and quantitatively and reflected the physical concepts well for the selected conceptual cases

Scenario-Based Tsunami Hazard Assessment For Java (Sunda) Trench Using Monte Carlo Simulations

Java (Sunda) trench lying along the eastern and southern coasts of Indonesia is one of the world's most active seismic zone. Java (Sunda) trench experienced devastating earthquakes and tsunamis throughout history. Despite the fact that about 14 years have passed since the 2004 Indian Ocean earthquake and tsunami, the seismic activity in this region is still intense. Thus, reliable estimation of the associated hazard of a possible large earthquake that can generate tsunami is vital for designing early warning systems, site selection of future critical infrastructures (CIs) and planning necessary mitigation measures for existing CIs and critical regions (CRs). Therefore, Scenario-based Tsunami Hazard Assessment (STHA) is performed for this region in this study. Historical earthquake data is compiled using ISC-GEM Global Instrumental Earthquake Catalogue for the region. Monte Carlo (MC) simulation method is used to generate random earthquake source parameters (i.e. magnitude, focal depth) along Java (Sunda) trench. The worst-case scenario among MC runs is selected and simulated using NAMI-DANCE tsunami simulation software. Critical Regions (CRs) and Critical Infrastructures (CIs) are identified and spatial distribution of the inundation levels along the eastern and southern coastline of Sumatra and Java Islands, focusing on these CRs and CIs is determined. It is observed that some of the CRs and CIs are vulnerable to potential high-risk tsunamis

Tests for financial market stability in emerging markets by using quantile regression

Bu çalışmada Avrupa, Orta Doğu ve Güney Afrika’da Morgan Stanley Capital International (MSCI) gelişmekte olan piyasalar endeksine giren ülkelerde finansal piyasa istikrarı Baur ve Schulze (2009)’nın önerdikleri kantil regresyon modeline dayalı yeni bir ampirik testle araştırılmıştır. Veri seti 1 Haziran 2002 ve 17 Şubat 2011 tarihleri arasındaki günlük hisse senedi piyasası logaritmik getirilerini kapsamaktadır. Çalışma sonuçları incelenen ülkelerden sadece Polonya ve Fas’ta finansal piyasa istikrarının var olduğunu göstermektedir.In this study, the financial market stability is investigated for the emerging market countries of Morgan Stanley Capital International (MSCI), Europe, the Middle East and Africa index by using quantile regression based new empirical test proposed by Baur and Schulze (2009). The daily logarithmic return dataset covers the period of June 1, 2002 to February 17, 2011. The results show that Poland and Morocco exhibit financial market stability among the investigated countries
