This study investigated water quality of the lake, a crucial element in protecting the ecological characteristics of a lake, and ensuring its sustainable use. The study involved use of Geographical Information Systems software to analyze the temporal and spatial changes in nutrient element concentrations that may deteriorate water quality and ecological characteristics of the lake. In the framework of the study, surface water samples were collected on the Lake Aktas in June, July, and August 2014 from nine stations selected at intervals in accordance with spatial analysis. The collected samples were measured for temperature, pH, dissolved oxygen, ammonium nitrogen, nitrate nitrogen, nitrite nitrogen, and orthophosphate. The obtained results were compared with the concentrations specified in Surface Water Quality Management Regulation published by the T. R. Ministry of Agriculture and Forestry. According to the findings, surface water classification and distribution for Lake Aktas included the following categories class I (WS-I/natural) in terms of oxygen, ammonium, and nitrate nitrogen, and class II (WS-II/undeveloped) in terms of nitrite. It was found that ammonium and phosphate levels have considerably increased in the last ten years, based on the comparisons made with the study sampled in Aktas Lake during 2004–2005 (Ozbay and Kilinc 2008).","PeriodicalId":51539,"journal":{"name":"Journal of Geography","volume":"52 1","pages":""},"PeriodicalIF":3.1,"publicationDate":"2021-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73026343","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although poljes have been one of the most studied landforms in the Anatolian karst, except for a few studies, no particular attention has been directed to provide a quantitative study on the morphometry and spatial distribution of poljes. In this study, an attempt has been made to present a comprehensive account of the basic morphometric characteristics and spatial distribution of the poljes within the karst regions in the Taurus karst belt, based on the critical review of the previous literature and detailed map studies. In this respect, 680 topographic maps, 1;25.000 scales with 10 m contour intervals, were analyzed and the 175 poljes were mapped. A data set based on the determination of morphometric parameters of the poljes was prepared, including X and Y centroid coordinates, the elevation of the floors above mean sea level, area, perimeter length, short and long axis lengths, elongation ratio, and circularity index. Within the scope of this dataset, the spatial distribution of the basic morphometric properties of poljes and the main factors controlling these properties were evaluated and interpreted. Most of the poljes in the Taurus karst belt are found in the area within the Isparta Angle located in the Western and Central Taurus. Most of the polje floor elevation (90%) is about between 447 and 1865 m above mean sea level though they are distributed in various elevations. Some poljes cover rather large areas, but the majority (65%) of them have a surface area of not more than 10 km sq. Due to the hydrological and tectonic characteristics of poljes, the circularity index values increase up to 28 and the elongation ratio values up to 9. The circularity index reaches higher values in fluvio-karst poljes dominated by fluvial processes, whereas the elongation ratio is higher in tectonically controlled poljes.","PeriodicalId":51539,"journal":{"name":"Journal of Geography","volume":"1 1","pages":""},"PeriodicalIF":3.1,"publicationDate":"2021-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89406839","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition to the changes experienced in climates for many years, the variability in climate elements due to the effects of climate change in recent years is critical. In this study, spatial and temporal changes of the year to year experienced variability and trends in storm records in Turkey were examined. Also, atmospheric teleconnections that control storm frequency were examined within the scope of the study. According to the results of the study, significant reductions in recent years in the frequency of storm events are being experienced across Turkey. Stormy days show statistically significant upward trends in the interior and eastern half of Turkey. All coastal regions of Turkey, especially the western coasts and terrestrial areas in the eastern parts of the Mediterranean region experienced statistically significant downward trends. In Turkey, the NAO’s activity on the number of stormy days is quite evident in winter. NCP and frequency of storms is characterized by significant positive correlations in eastern Turkey. When evaluating the relationships between Turkey’s storm frequency and Atmospheric oscillations, one can say that NAO and AO are atmospheric oscillation indices that best explain storm frequency across the country.","PeriodicalId":51539,"journal":{"name":"Journal of Geography","volume":"63 1","pages":""},"PeriodicalIF":3.1,"publicationDate":"2021-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82353763","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This canyon is located in the upper basin of the Dicle River in the subbasin of the Sinebel Creek and Botan River. The Sinebel Creek valley network built on Neogene deposits was exposed to anticlinal uplift between Korkandil Mountain and Gulle Hill. The stream responded to this rise by being buried in the topography and developed a narrow-deep canyon structure. Therefore, in addition to the antecedent character, epigenetic features are also observed in the canyon. The canyon has a polygenic character because karstification, fluvial processes, and tectonism have a common effect in the development of the canyon valley. In and around the canyon, which is an example of tectonically controlled karstification in the folded karst zone belt, in addition to the karst topography, fluvial shapes and mass movements are also encountered. The study area, which has a rich geomorphic landscape, has a rugged topographic structure. In this study, the morphogenetic evolution of the Masiro Canyon and geomorphic characteristics of its immediate surroundings are clarified. For this purpose, field studies were conducted, literature was reviewed, and maps and figures related to the area were produced in a geographical information system environment using a 12.5-m-resolution digital elevation model.","PeriodicalId":51539,"journal":{"name":"Journal of Geography","volume":"64 1","pages":""},"PeriodicalIF":3.1,"publicationDate":"2021-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76514815","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
