Several natural disasters have occurred from the days of biblical Noah until now. These natural disasters have taken various forms like; floods, earthquakes, volcanic eruption tsunamis, tornadoes, landslides, hurricane, and among others. Within the past decades, flooding has become a global pandemic which hampers economic and social development. This global phenomenon has affected 4 million people, loss of lives and economic damages of approximately US$ 780,500,000 in Ghana. It is therefore necessary to ascertain the causes of flood in Ghana and propose an approach that can be helpful to mitigate the flood impacts and save lives and properties. A case study in Accra, the capital of Ghana, will be employed in this paper since it has recorded the highest flood frequency, and how best it can be managed using the Integrated Flood Risk Management approach for the 21st Century. This record was migrated from the OpenDepot repository service in June, 2017 before shutting down.


Evaluation of numerical weather prediction models for flash flood warnings in Turkey
Aksoy, Mehmet; Yücel, İsmail; Department of Civil Engineering (2020-10-15)
Flash floods are among the most destructive natural disasters in both Turkey and world that cause loss of life and property. In this study, monthly distribution of heavy rainfall events in the period of 2015-2019 is examined to show the frequency and distribution of flash floods associated with these heavy rainfall events in Turkey. The monthly distribution of lightning observations for the period of 2015 and 2019 is also studied to release the relationship between heavy rainfall events and lightning ...
Operation of the water control structures
Bozkurt, Okan Çağrı; Merzi, Nuri; Akyürek, Sevda Zuhal; Department of Civil Engineering (2013)
Floods are one of the most important natural disasters regarding damages caused by them. Major reasons of huge damages of floods are unplanned urbanization, narrowing of river beds and incorrect operation of water control structures. Geographic Information Systems (GIS) can provide important tools to be used in flood modeling studies. In this study, Lake Mogan, Lake Eymir and İncesu Detention Pond subbasins are studied for flooding events within GIS framework. These subbasins are important catchment areas o...
Flood risk mapping using economic, environmental and sociadimensions
Yeğin, Murat; Kentel Erdoğan, Elçin; Department of Civil Engineering (2015)
Flood is one of the most destructive natural hazards in Turkey. It is unavoidable but its impacts can be minimized by taking necessary precautions. Flood risk mapping is a developing concept and it is used to determine economically, environmentally and socially risky areas. European Council stipulated the member countries to prepare flood hazard maps showing extents of low, medium and high probability flood events. These maps should also be prepared for Turkey during the European Union harmonization process...
Earthquake damage detection using watershed segmentation and intensity-gradient orientation approaches
Sümer, Emre; Türker, Mustafa; Department of Geodetic and Geographical Information Technologies (2004)
Earthquake is one of the most destructive natural disasters on earth. Rapid and reliable post-quake damage assessment has an important role to reduce the drastic effects of an earthquake by setting the responsible agencies in motion. In this study, the collapsed buildings due to earthquake were detected from post-event aerial images. Two approaches were proposed to detect the collapsed buildings. These approaches were implemented in a selected urban area of Golcuk. The first approach was based on the analys...
Tsunamis bridging science engineering and society
Kanoğlu, Utku; Bernard, Eddıe; Synolakıs, Costas (null; 2015-06-22)
There have been significant advances in tsunami science since the devastating 2004 Boxing Day tsunami. Yet, the 2011 Japan tsunami dramatically demonstrated that tsunamis continue to avoidably take lives and cause significant damage. Broadcasted live to a stunned world audience, the trail of destruction in 2011 in probably most tsunami ready nation underscores the difficulties of implementing practical advances in hazard mitigation. The Philosophical Transactions A theme issue entitled ‘Tsunamis: Bridging ...
