In recent years, flooding has become an increasing concern across many parts of the world of both the general public and their governments. The climate change inducing more intense rainfall events occurring in short period of time lead flooding in rural and urban areas. In this study the flood modelling in an urbanized area, namely Samsun-Terme in Blacksea region of Turkey is performed. MIKE21 with flexible grid is used in 2-dimensional shallow water flow modelling. 1 x 1000(-1) scaled maps with the buildings for the urbanized area and 1 x 5000(-1) scaled maps for the rural parts are used to obtain DTM needed in the flood modelling. The bathymetry of the river is obtained from additional surveys. The main river passing through the urbanized area has a capacity of 500 m(3) s(-1) according to the design discharge obtained by simple ungauged discharge estimation depending on catchment area only. The upstream structural base precautions against flooding are modelled. The effect of four main upstream catchments on the flooding in the downstream urban area are modelled as different scenarios. It is observed that if the flow from the upstream catchments can be retarded through a detention pond constructed in one of the upstream catchments, estimated Q(100) flood can be conveyed by the river without overtopping from the river channel. The operation of the upstream detention ponds and the scenarios to convey Q(500) without causing flooding are also presented. Structural management measures to address changes in flood characteristics in water management planning are discussed.

Utilization of numerical weather prediction models for flood planning and operational studies in datascarce basins Bozkurt, Okan Çağrı; Merzi, Nuri; Akyürek, Sevda Zuhal; Department of Civil Engineering (2020-9) With the increasing rates of urbanization, floods have become a more critical problem day by day. Consequently, the perception arises that the flood control structures have become insufficient. Well-calibrated weather forecasting and hydrological models are important complementary tools to reduce the damage caused by floods. Such applications can yield results as useful as structural measures. In this study, the effects of the use of numerical weather forecasting and hydrological models on structural and no...
Impact analysis of flood in Accra, Ghana Asumadu-Sarkodie, Samuel; Owusu, Phebe Asantewaa; Rufangura, Patrick (2017-6-19) Within the past decades, flooding has become a global pandemic, which hampers economic and social development. This global phenomenon has led to loss of lives and economic damages in many countries including Ghana. On June 3rd 2015, Accra, Ghana's capital experienced an unprecedented flash flood event, coupled with an explosion at a Goil filling station that resulted in a death toll of over 152 lives. It is therefore necessary to explore new ideas and approaches that can be incorporated to existing structur...
Life cycle assessment of a basic external drywall system in Turkey Akgül, Çağla; Özcelik, Gökçe (null; 2014-10-24) The construction sector, being one of the greatest consumers of raw materials, has been under the spotlight for many years in parallel to the increased environmental awareness. Specifically, building of walls are of critical importance. For each wall element, there are different manufacturing steps; but, in general, the emissions from a wall element are dominated by one or two manufacturing steps. For example, for concrete, both energy use and calcination in cement manufacturing are in focus; for clay brick...
Assessment Study of 21st Century Drought Conditions at Shasta Dam Based on Dynamically Projected Water Supply and Water Demand Trinh, T.; Ishida, K.; Kavvas, M.L.; Ercan, Ali; Carr, K. (2017-01-01) Along with socioeconomic developments, and population increase, natural disasters around the world have recently increased the awareness of harmful impacts they cause. Among natural disasters, drought is of great interest to scientists due to extraordinary diversity of their severity and duration. Motivated by developing a potential approach to investigate future possible droughts in a probabilistic manner based on climate change projections, a methodology to consider thirteen future climate projections bas...
Coastal Tsunami and Risk Assessment for Eastern Mediterranean Countries Yavuz, Cüneyt; Kentel Erdoğan, Elçin (null; 2017-12-17) Tsunamis are rarely experienced events that have enormous potential to cause large economic destruction on the critical infrastructures and facilities, social devastation due to mass casualty, and environmental adverse effects like erosion, accumulation and inundation. Especially for the past two decades, nations have encountered devastating tsunami events. The aim of this study is to investigate risks along the Mediterranean coastline due to probable tsunamis based on simulations using reliable historical ...
