This study aims to examine a set of alternatives as remedial measures for the flood management purposes in order to protect the northern part of Nicosia which has been affected by major flooding events in recent years. In this context, at first, in order to obtain the run-off hydrographs at the entrance of reservoirs, the hydrological modelling of the ungauged catchments of Kanlikoy and Gonyeli Reservoirs which are located at the upstream part of the city was performed. In the simulation of these rainfall–run-off processes for different extreme precipitation events, the HEC-HMS software was employed using Soil Conservation Service Unit Hydrograph approach. In hydraulic modelling, the branches of Pedieos (Kanlidere) River and its urbanized floodplain were modelled by coupling the models of one-dimensional (1D) MIKE 11 and two-dimensional (2D) MIKE 21 using MIKE FLOOD tool. The calibration of the coupled hydrodynamic model was carried out by locally modifying the Manning’s roughness coefficients of the floodplains to match with the observed flood inundation extent of 2010 Flood. Consequently, the calibrated model showed nearly 94% similarity in terms of simulating the flood extent areas. Amongst different alternatives, the final proposed solution consisting of implementation of a new nearby upstream reservoir in Kanlikoy, dredging Gonyeli Reservoir and raising the crest elevations of its embankment and spillway, and restoration of possible channels sufficiently contributed to the mitigation of inundation problem and protected the northern part of Nicosia against the flooding events up to 500-year return period.

The evaluation of public awareness and community preparedness parameter in GIS-based spatial tsunami human vulnerability assessment (MeTHuVA) Tüfekçi Enginar, Duygu; Süzen, Mehmet Lütfi; Yalçıner, Ahmet Cevdet (Springer Science and Business Media LLC, 2020-11-01) Catastrophic tsunami events in the past decades reveal the need to improve disaster risk reduction management systems. Although the actions born with this need began in the countries affected by the recent major events, mainly in Indonesia, after the 2004 Indian Ocean tsunami and in Japan, after the 2011 Tohoku tsunami, it started to spread to other tsunami-prone coastal areas. The development of risk reduction strategies begins with determining the possible worst-case scenarios for the region and identifyi...
Evaluating the use of bias-corrected radar rainfall data in three flood events in Samsun, Turkey Ozkaya, Arzu; Akyürek, Sevda Zuhal (Springer Science and Business Media LLC, 2019-09-01) In applied hydrology, estimating the peak flood discharge in ungauged or poorly gauged river sections is vital for urbanized areas. Spatially distributed rainfall data such as weather radar data may be a good choice to represent the driving force in hydrologic models for ungauged regions. However, it is important to examine the accuracy of this product, especially over mountainous regions. The bias between radar rainfall and rain gauge rainfall can be progressively removed by using information provided by r...
Seismic damage assessment based on regional synthetic ground motion dataset: a case study for Erzincan, Turkey Karim Zadeh Naghshineh, Shaghayegh; Askan Gündoğan, Ayşegül; Erberik, Murat Altuğ; Yakut, Ahmet (Springer Science and Business Media LLC, 2018-07-01) Estimation of seismic losses is a fundamental step in risk mitigation in urban regions. Structural damage patterns depend on the regional seismic properties and the local building vulnerability. In this study, a framework for seismic damage estimation is proposed where the local building fragilities are modeled based on a set of simulated ground motions in the region of interest. For this purpose, first, ground motion records are simulated for a set of scenario events using stochastic finite-fault methodolo...
Flood forecasting and analysis within the Ulus Basin, Turkey, using geographic information systems Usul, Nurunnisa; Turan, Burak (Springer Science and Business Media LLC, 2006-10-01) Floods have been the most severe natural disasters in the West Black Sea Region of Turkey for many years; therefore Ulus Basin is selected as a study area for a thorough hydrologic flood analysis. The lack of embankments around the Ulus River and careless changes to the riverbed made by villagers, resulted in major flood events in the basin, causing significant damage in the area. In this study, the hydrodynamic characteristics of the basin and the riverbed are determined by calibrating the hydraulic module...
Patterns in the Turkish reinsurance claim data, 1998-2002: An application of the extreme value theory Başbuğ Erkan, Berna Burçak (Springer Science and Business Media LLC, 2006-10-01) The devastating 1999 Marmara and Duzce earthquakes led to a significant increase in the earthquake studies in Turkey in geological, engineering and financial aspects. Extreme Value Theory (EVT) has a range of applications from stock market changes to natural disasters like floods and hurricanes. Here EVT is fitted to the ordinary and earthquake reinsurance claims of Turkey.
