Flood forecasting and analysis within the Ulus Basin, Turkey, using geographic information systems

Usul, Nurunnisa
Turan, Burak
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 of the MIKE 11 modeling system with the observed 1991 flood. Then, for the 25-, 50- and 100-year floods the highest water levels in the river are forecasted by integration of the MIKE 11 hydrologic and hydraulic modules. Afterwards, inundation maps are obtained by using together the hydraulic and GIS modules of the MIKE 11 system.


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.
Damage risk assessment of breakwaters under tsunami attack
Ergin, Ayşen (Springer Science and Business Media LLC, 2006-10-01)
Turkey was struck by two major events on 17 August and 12 November 1999, named Izmit (M-w = 7.4) and Duzce (M-w = 7.2) earthquakes, respectively. Rubble mound breakwaters in Izmit Bay experienced little damage, as forecasted by the new risk assessment model in which tsunami occurrence risk was included in the damage estimations. In order to determine the occurrence probability of structural damage under design conditions, including the environmental loading parameters of tsunami and storm waves, tidal range...
Landslide risk assessment and management by decision analytical procedure for Derekoy, Konya, Turkey
Duzgun, S. B.; Ozdemir, A. (Springer Science and Business Media LLC, 2006-10-01)
The Derekoy landslide threatening the town of Derekoy, Konya, Turkey is investigated in order to assess and manage the associated risk. Derekoy town, located 12 km west of Konya city center, which is the second largest city in central Anatolia, has been extending due to the demand for new settlement places in Konya for the last decade. As most of the town is situated on the slopes of Meram river valley, on which the slope movements are observed, the risk of landslide has been increasing due to these new set...
Environmental geological investigations at the Van open dump site, southeastern Turkey
Akgün, Haluk (Springer Science and Business Media LLC, 2000-04-01)
This study evaluates the geological, hydrogeological and hydrological conditions at the I waste dump site of the Van municipality in eastern Anatolia, Turkey. A geological map and a three-dimensional view of the project site have prepared. All lithological units exposed at and near the dump site have been determined and their boundary relationships identified. Drainage basin characteristics of the dump site along with the water bearing properties of different lithological units have been assessed. For the r...
Developing flood mitigation measures for the northern part of Nicosia
Zaifoglu, H.; Yanmaz, Ali Melih; Akintug, B. (Springer Science and Business Media LLC, 2019-09-01)
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–r...
