Rapid land use/land cover changes have taken place in many cities of Turkey. Land use and land cover changes are essential for wide range of applications. In this study, Landsat TM satellite imageries date from 1987, 1993, 2000 and 2010 were used to analyse temporal and spatial changes in the Western Black Sea Region of Turkey. Zonguldak and Eregli two largest and economic important cities which have been active coal mining and iron fabric areas. Maximum Likelihood Classification technique was implemented and the results were represented in classes of open area, forest, agricultural, water, mining, urban and pollution in the sea. Ur . . .ban areas on both cities increased from 1987 to 2010. The agricultural and open areas from 1987 to 2010 decreased in parallel to land use and land cover change in both cities. Meanwhile, forest areas increased continuously with about 20 % from 1987 to 2010 in both cities. As industrial activity, the coal fields doubled from 1987 to 2010. © 2013 Indian Society of Remote Sensing Daha fazlası Daha az

Power production using fossil fuels can bring significant adverse effects on the surrounding environment. In this study, detection of industrial ash turbidity from a coal-fueled power plant in marine water and its interaction with marine environment were evaluated using 3 satellite imageries. To this aim, e-Cognition v.4.0.6 software was utilized to perform detection, classification and comparison of the polluted area in the aquatic marine environment using Landsat-5 TM satellite imageries and Landsat-7 ETM + satellite imagery. Total polluted area, obtained from Landsat satellite imageries, was classified into 3 regions: highly poll . . .uted, moderately polluted and less polluted region, and their polluted field dimensions were evaluated to be 10.19 km2and 7.50 km2 for Landsat TM imageries as well as 37.73 km2 for Landsat ETM+ imagery. Total suspended solids (TSS) levels were determined as 2380±213 mg.L-1, 361±118 mg.L-1 and 57±24 mg.L-1for the highly, moderately and less polluted regions, respectively. This study may serve as a database for future comparisons to identify the trend of improvement or deterioration of coastal environment of Zonguldak Daha fazlası Daha az
