Numerical modeling of Samsun Mert River floods

ÜLKE, Aslı | BEDEN, Neslihan | DEMİR, Vahdettin | MENEK, Necati

Floods are considered one of the most important natural disasters after earthquakes in Turkey. As a result, there is currently great public interest in this issue and it is necessary to intensify research activities in order to understand natural disasters better and to reinforce risk management. The effect of climate change on meteorological events causes an increase in extreme events such as excessive precipitation in some regions. An extreme natural event becomes a disaster when it has a large impact on human settlements and activities. Study area Samsun city is placed in the north of Turke ...Daha fazlası

Trend Analysis of Precipitation, Temperature and Wind Data in Samsun (Turkey)

ÜLKE, Aslı | BEDEN, Neslihan | DEMİR, Vahdettin

Climate change effects have been remarkably perceived today; the determination of trends in precipitation, stream flow, winds, evaporation, and temperatures has become considerable for the planning and management of water resources and engineering projects. Nowadays there is a lot of studies have been made in progress on global and regional climate changes in literature. The objective of this study is to analyze monthly, annual and seasonal trends in average temperature, total precipitation, and average wind data by Mann- Kendall, linear trend and Sen’s Trend tests. The data sets are obtained ...Daha fazlası

Flood Modeling of Samsun/Atakum Region by GIS Tools

BEDEN, Neslihan | DEMİR, Vahdettin | ÜLKE KESKİN, Aslı

Study area Samsun/Atakum province is almost under threat of flooding in each year. In this region, the main reason of devastating flood is the influence of the Degirmen stream especially during March, April, and July and due to seasonal rainfall, which eventually makes the district vulnerable to flooding. In addition, the human-based constructions and the collapse of water retaining structures are among the main causes of flooding. In this study flood risks of Samsun Degirmen stream determinate by MIKE 11 and GIS. Numerical model selection for studies provides advantages in developing and chan ...Daha fazlası

Flood Modeling by GIS Tools

BEDEN, Neslihan | DEMİR, Vahdettin | ÜLKE, Aslı

In this study flood risks of Samsun Degirmen stream determinate by MIKE 11 and GIS. In this study, MIKE powered by DHI software used for numerical 1D modeling of study area. The hydrological and hydraulic data for the study area were obtained from the Turkish General Directorate of State Hydraulic Works. ArcGIS program was used for creating a triangulated irregular network data (TIN). The flood inundation maps demonstrated that some areas, from the upstream to downstream of the Degirmen stream basin is affected from 100 year and 500 year return period events.

Comparison Of 2d Hydraulic Models For Flood Simulation On The Mert River Turkey

BEDEN, Neslihan | DEMİR, Vahdettin | ALRAYESS, Hesham | KESKİN, Aslı Ülke

As well as all over the world, Turkey exposures to floods more frequently as a result of climate change. The study area, Mert River is located in Samsun city north of Turkey and also frequently exposed to floods and flood management studies in the region are carried out in progress by local administrations. The aim of this study is to compare different hydraulic modeling methods on Mert River, mainly related to floodplain modeling. Therefore, different hydraulic models have been applied to the Mert River. Two types of 2D models are examined in this paper, these are respectively MIKE 21 and FLO ...Daha fazlası

Homogeneity and Trend Analysis of Long Term Temperatures in the Middle Black Sea Region

DEMİR, Vahdettin | ZEYBEKOĞLU, Utku | BEDEN, Neslihan | ÜLKE KESKİN, Aslı

In this study long-term trend analysis of maximum and minimum monthly temperatures are determined in the Middle Black Sea Region of Turkey. Data is obtained from Turkish State Meteorological Service for the period of 1964 to 2015 for Amasya, Çorum, Ordu, Samsun, Sinop and Tokat stations throughout the Middle Black Sea Region. Primarily homogeneity of the data is examined with Run, Buishand and Von Neumann homogeneity methods with a 99 % confidence level. Linear trend, Mann-Kendall and Innovative Sen’s trend methods are used for trend analysis with a 99 % and 95 % confidence levels. Amasya and ...Daha fazlası

Samsun İlinde SPI ve PNI Kuraklık İndekslerinin Eğilim Analizi

BEDEN, Neslihan | DEMİR, Vahdettin | ASLI, Ülke Keskin

Kuraklık ekosistemleri ve toplumu birçok yönden etkileyen karmaşık bir doğal tehlikedir. Meteorolojik değişkenliğin bir sonucu olan kuraklığın etkilerini hafifletmek için su kaynakları yönetim stratejilerinin geliştirilmesi ve kuraklık riskinin değerlendirilmesi gereklidir. Su kaynaklarının planlamasında ve yönetiminde kuraklıkların tanımlanması, izlenmesi ve karakterizasyonu büyük önem taşımaktadır. Kuraklığın belirlenmesinde kullanılan yöntemlerden biri yağış değerleri yardımıyla bulunan kuraklık indeksleridir. Bu çalışmada, Samsun ili Meteoroloji Gözlem İstasyonu (17030-MGİ) 1960-2015 yılla ...Daha fazlası
