Overpopulation has some administrative, social, economic and environmental problems in the world. Istanbul is the city with the largest population in Turkey causing pollution problems on the surface water reserves. Buyukcekmece Reservoir is one of the 8 major drinking water reservoirs of Greater Metropolis Istanbul. Buyukcekmece Watershed covers the third largest drinking water source of Istanbul, Buyukcekmece Lake. The purpose of this study is to assess the water quality changes of Buyukcekmece Reservoir using Remote Sensing and Geographic Information System technologies in support of operational management. The results are obtained by image processing of different spectral and spatial resolution data belonging to dates of 1992, 1996, 2000, 2001, 2004, 2005 and 2006. Rapid population growth, industrial development, lack of sufficient infrastructure, and also illegal settlements highly affect the watersheds and water quality as a typical reflectance of urban sprawl in mega cities of developing countries. The pollution load from settlements and industrial areas to the watersheds has a negative effect on drinking water quality, and also many species in the examined lake.

Water Resources Assessment of Northern Cyprus for a Sustainable Management Hilal, Adnan Yaser Adnan; Bozkaya Schrotter, Bengü; Akıntuğ, Bertuğ; Sustainable Environment and Energy Systems (2021-2-11) Increasing world population and industrialisation lead to a rapid rise in water consumption and demand. As a result, both surface and sub-surface water resources were overexploited in most parts of the world, including Northern Cyprus in the Eastern Mediterranean region over the past years. In this study, the spatial distribution and temporal variation of daily, monthly, seasonal and yearly rainfall patterns in Northern Cyprus are analysed using Concentration Index, Precipitation Concentration Index, Season...
Climate change impacts on lakes: an integrated ecological perspective based on a multi-faceted approach, with special focus on shallow lakes Jeppesen, Erik; Meerhoff, Mariana; Davidson, Thomas A.; Trolle, Dennis; Sondergaard, Martin; Lauridsen, Torben L.; Beklioğlu, Meryem; Brucet, Sandra; Volta, Pietro; Gonzalez-Bergonzoni, Ivan; Nielsen, Anders (PAGEPress Publications, 2014-01-01) Freshwater ecosystems and their biodiversity are presently seriously threatened by global development and population growth, leading to increases in nutrient inputs and intensification of eutrophication-induced problems in receiving fresh waters, particularly in lakes. Climate change constitutes another threat exacerbating the symptoms of eutrophication and species migration and loss. Unequivocal evidence of climate change impacts is still highly fragmented despite the intensive research, in part due to the...
Rehabilitation of water supply systems Toğrul, Nevzat; Merzi, Nuri; Department of Civil Engineering (2015) Management of water supply systems by an economic and efficient way is a significant issue for water authorities. Selection and operation of water supply elements appropriately to satisfy water need affects the energy consumption of the system. This study aims to constitute a long term rehabilitation plan for water supply elements (only storage tanks, pumps and transmission line pipes are in the scope of the study). A case study has been performed on N8.3 pressure zone of Ankara water distribution network. ...
Water footprint assessment of mining and processing of gold Güney, Emre; Demirel, Nuray; Department of Mining Engineering (2022-1-3) Water management in mining industry has strategic importance due to the increasing water scarcity. Water Footprint Assessment (WFA) is a systematic way that provides an assessment of sustainable water management from multiple perspectives. The main objective of this study is to analyse the water footprint of mining and processing of gold and identifying hotspots of carbon in pulp (CIP) gold processing using WFA and life cycle assessment (LCA). In this study, after determining the goal and scope, data was co...
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...
