In this study, it is aimed to reveal the soil and land use of Sarıgöl district of Manisa province (Türkiye) with the help of Geographical Information Systems tools. For this purpose, General Directorate of Soil Water data were digitized and areal and proportional distribution maps and statistical data were obtained by means of ArcMap 10.3 software. The surface area of the study area is 431.525 km2 and it is located at the intersection of 4 provinces in the Aegean Region. While the slope value is between 0-2 % in 21.58% of the total land area of the district, whose elevation varies between 170 and 1338 meters, low slope lands are generally located in Sarıgöl and Afşar plains and intensive agriculture is carried out in these areas. The soil groups of the district are calcareous brown forest soils (202.2 km2), alluvial soils (102.2 km2), calcareous brown soils (96.8 km2), kolluvial (19.5 km2) and rendzinal (7 km2). Erosion occurring at severe and very severe levels is observed in 281.81 km2 area, which shows that 65% of the land in the study area is at risk of losing its soil resources. As a matter of fact, the soil depth is less than 50 cm in 282.796 km2 of the total land area. Concave slopes, where the erosion effect occurs more slowly than other slope types, are observed in 200.788 km2 (46%), flat areas 154.142 km2 and convex slopes 76.595 km2. Agriculture is practised in 48% of the total land area of the district. When we look at the other usage areas, forest occupies 29%, heathland 18%, pasture 3%, settlement areas and river floodplains 2%. Class I, II, III and IV lands of the district have a 35% share with 147.076 km2, while class V, VI, VII, and VIII lands correspond to 65% of the land area with an area of 278.398 km2.

Bu çalışmada ulusal öneme haiz sulak alanlar kapsamında tescillenen Yeşilırmak Deltası’nın yaklaşık 18,5 km’lik kıyı bölümünde gerçekleşen erozyon uzaktan algılama ve Coğrafi Bilgi Sistemleri (CBS) yardımıyla araştırılmıştır. 1985–2022 periyodunda gerçekleşen kıyı çizgisi değişimlerinin belirlenmesi ve erozyonun derecesinin anlaşılabilmesi için 1985, 1990, 1996, 2001, 2006, 2011, 2017 ve 2022 yıllarına ait Landsat-5 TM/Landsat-8 OLI uydu görüntüleri kullanılmıştır. Uydu görüntülerinden kıyı çizgilerinin belirlenmesinde normalize fark su indeksi (NDWI) ve modifiye normalize fark su indeksi (MNDWI) entegre edilmiştir. Yıllık kıyı çizgisi değişim oranları 1985–2022 periyodunda sekiz farklı yıla ait kıyı çizgilerinden doğrusal regresyon oranı (LRR) yöntemiyle %95 güven düzeyinde hesaplanmış, Yeşilırmak Nehri’nin batı kesimindeki Bölge-1’de maksimum -25,8 m/yıl, doğu kesimindeki Bölge-2’de maksimum - 7,7 m/yıl’a ulaşan erozyon oranı belirlenmiştir. Kıyı çizgisi değişimleri sınıflandırıldığında deltanın %34’ü yüksek, %9’u orta, %18’i düşük derecede olmak üzere %61’inde erozyon gerçekleştiği anlaşılmıştır. 1985– 2022 periyodunda erozyonla kaybedilen alanlar çakıştırma analizi ile belirlenmiş, Bölge-1’de 179,23 ha ve Bölge-2’de 82,22 ha olmak üzere toplam 261,45 ha alanın erozyon ile kaybedildiği görülmüştür. Analiz sonuçları, Yeşilırmak Deltası kıyılarındaki erozyon, birikim ve stabil alanların belirlenerek kıyı dinamiklerinin ve erozyon tehlikesinin daha iyi anlaşılmasına katkı sağlamış ve kıyı çizgisi değişimlerinin belirlenmesinde Landsat görüntüleri ve LRR yönteminin etkinliğini ortaya çıkarmıştır

This study was conducted to determine the erosion risk caused by the change in land use/cover in Acısu Basin between 2000-2018. In the study where the RUSLE model was preferred, other parameters were kept constant, but the model was applied to the model twice separately with the land cover/use data of the relevant years and two independent erosion maps were created. With the study, how much soil is lost in Acısu Basin during the year, which regions are more exposed to erosion, and their distribution was classified and revealed. During the study, the data obtained from satellite images, topographic maps, and field observations were analyzed by GIS and IA techniques. Kappa statistical test was used for the accuracy of the findings. It was determined that the most change in the direction of growth in the basin in 18 years from 2000 to 2018 was 17.08 km² (3.35%) in grassland and pasture areas. On the other hand, it was determined that the highest change in the direction of the decrease occurred in plant change areas with a value of -23.05 km² (4.49%). It is seen that the change in the surface cover of the study area in this time interval caused the expansion of very light, light, and moderate erosion areas. Due to this change in the land surface of Acısu Basin covering 18 years, it was determined that there was an increase in the annual total of 197 t ha-1 y -1 and an increase in the average soil loss amount of 49 t ha-1 y -1 .

This study investigated erosion along the approximately 18.5 km coastal section of the Yeşilırmak Delta, a nationally important wetland, using remote sensing and Geographic Information Systems (GIS). Landsat-5 TM/Landsat-8 OLI satellite images from 1985 to 2022 (1985, 1990, 1996, 2001, 2006, 2011, 2017, and 2022) were used to determine shoreline changes. The shoreline determination process involved the combination of the normalized difference water index (NDWI) and the modified normalized difference water index (MNDWI). Annual rates of shoreline change were calculated using the linear regression rate (LRR) method within a 95% confidence level. Results showed a maximum erosion rate of -25.8 m/year in Zone-1, located in the western part of the Yeşilırmak River, and -7.7 m/year in Zone-2, situated in the eastern part. Erosion affected 61% of the delta, with 34% experiencing high-level erosion, 9% medium-level erosion, and 18% low-level erosion. Overlay analysis identified a total loss of 261.45 ha during 1985-2022, with 179.23 ha in Zone-1 and 82.22 ha in Zone-2. These findings enhance understanding of coastal dynamics by delineating erosion, accretion, and stable areas in the Yeşilırmak Delta. Furthermore, the study highlights the effectiveness of Landsat images and the LRR method in assessing shoreline changes. [ABSTRACT FROM AUTHOR]

The research was carried out to determine the morphometric analysis parameters of the Burdur Lake Watershed. In addition, the erosion situation in the watershed has been evaluated with the help of morphometric parameters. The data basis of the research was created using the Digital Elevation Model (DEM) obtained from Shuttle Radar Topography Mission (SRTM). The determination of the stream indexes used in the analyzes was made via the ArcGIS 10.2 program. In this context; When the morphometric analysis results of the parameters of the linear, areal and relief morphometries of the watershed are examined; bifurcation ratio 3.42, stream length ratio 3.46, drainage density 1.25, stream frequency 0.95, form factor 0.25, gravelius index 2.66, circularity ratio 0.14, elongation ratio 0.28, basin relief 1534, relief ratio 0.013, relative relief 0.29, ruggedness number respectively 1.92 and the hypsometric integral value was found to be 0.28. In general, it has been found that the infiltration capacity of the watershed is high, stream frequency and flood sensitivity are low. In consequence of morphometric analysis, it was determined that the area had arid climatic conditions and weak vegetation. As a result, it has been concluded that the erosion risk is relatively low in most of morphometry parameters. According to these results, it can be said that morphometric analysis are an important tool for interpreting the erosion situation in the watershed.

Bu çalışmanın amacı, sürüntü hareketinin yanı sıra yoğun bir askı hareketinin olduğu Sera Deresi Havzası’nda askıda katı madde (AKM) taşınımını gözlemlemek ve ana kol üzerinde inşa edilen tersip bentlerinin (TB) taşınıma olan etkilerini değerlendirmektir. Havzada seçilen 10 AKM gözlem istasyonundan, Haziran-Kasım 2019 döneminde ayda dört kez olacak şekilde su örnekleri toplanmış ve AKM (mg/L) belirlenmiştir. Havzadaki ilk gözlem istasyonunun mansabında yer alan TB1’in taşınan AKM’nin %16,5’ini tutarak mansaba geçişini engellediği ve Sera Gölü’nde havzadan taşınan AKM’nin %69,4 gibi büyük bir kısmının tutulduğu tespit edilmiştir. Havzada işletilmekte olan Derecik isimli akım gözlem istasyonundan (AGİ) seviye okumaları yapılarak ilgili kesitten geçen debiler (Q, m3) belirlenmiş ve AKM yükleri (ton) hesap edilmiştir. TB2 ile TB3 arasında ve Derecik AGİ’nin hemen mansabında yer alan istasyonda ortalama günlük debiler ve AKM yükleri yazın 99.000 m3/gün ile 24,6 ton/gün ve sonbaharda 83.945 m3/gün ile 2,5 ton/gün olarak hesap edilmiştir. Akarsu yataklarına moloz ve hafriyat dökümünün yanı sıra yerleşim birimlerinden yapılan evsel atık su deşarjlarının da AKM miktarının artışında etken olduğu havzada tersip bentleri sayısal olarak yetersiz kalmaktadır. Çok dik ve sarp eğimli orman arazilerine sahip Sera Deresi Havzası’nın membaındaki yan kollar üzerinde de geçirimsiz tersip bentlerinin yanı sıra geçirimli tersip bentlerine de ihtiyaç duyulduğu sonucuna ulaşılmıştır.

This study reveals the status of erosion risk, which is a very important soil and environmental problem, in Gaziantep in order to test the reliability of the fuzzy method. The study evaluates vegetation cover, lithological structure, slope, and precipitation as erosion indicators to determine the effectiveness of the frequently used analytic hierarchy process (AHP) and Fuzzy methods at identifying erosion risk. A weight value was assigned to each parameter using both the AHP and fuzzy methods; afterwards, mapping and analysis were carried out in the program Geographic Information System (GIS). The compatibility of both methods has been provided by comparing the values at 100 geographic points that had been selected. In accordance with these results, the AHP and fuzzy methods were determined to be highly compatible with each other. When considering the evaluation obtained as a result of the methodological comparison, while values were observed to be very similar in the categories of medium and high erosion, the similarity rates decreased in the categories of low and very low erosion. As a result, the fuzzy method has been revealed to be able to be used exclusively for evaluating erosion risk in areas with semi-arid climate characteristics and to even be an effective tool for guiding actions at preventing erosion.

The present study was conducted to determine the areas and volumes of erosion zones in Thrace peninsula using geographical information systems (GIS). Measurements made with remote sensing both save time and prevent excess workforce. In addition, it is less costly than satellite images that can be purchased for areas where drones can be shot. For this purpose, 13 erosion sites with different environmental characteristics were examined and images were obtained with an unmanned aerial vehicle (UAV) in the study area. To calibrate the UAV data, the boundaries were determined using nature-friendly white paint. Then, all measurements (lengths, angles, etc.) of these areas were calculated from various altitudes. Volume of the determined areas then processed using GIS software and a graphic program named "Autodesk Inventor". All of the UAV tasks were taken under suitable weather condition in order to avoid any difference in the images. Furher, the UAV images to be combined were obtained under similar weather conditions to ensure that factors such as light and shadow do not cause any deviation in the calculations and create visual differences. Images were taken from a total of 13 erosion areas and WGS 1984 (World Geodetic System 1984) was used as the coordinate system in the present study. Orthomosaic images of these areas were created by combining the images. In addition to the areas and volumes of the regions in the images, calibration analyzes were also made. Using a small area for calibration in the study increased the accuracy of area measurement rate above 90%, while this rate was found between 60 - 78% in volume measurement depending on the flight altitude. 12 photos were used in the image taken from a height of 100 meters and 103 from a height of 10 meters in the calibration from approximately 100 m². Accordingly, the volumetric accuracy rate was found to be 78.57% in the image taken from a height of 10 meters from the ground. [ABSTRACT FROM AUTHOR]

Drought is one of the important problems influencing forest ecosystems. This problem has been getting more attention recently due to impacts of global warming. Drought could decrease aboveground growth of plants by 30-70% and restrict their natural distribution boundary and biodiversity. Growth of trees is controlled by the availability of water up to 80-90%. In Turkey, drought triggered forest tree mortalities have been observed in leeward sides of Black Sea Region, Central Anatolian Region and Aegean Region. Dead trees of Scots pine and oriental spruce found in Black Sea Region, of black pine, scots pine and fir in Central Anatolian Region and of brutian pine in Aegean Region. In addition, drought triggered bark beetle infestation that caused dying of thousands of spruce trees in Eastern Black Sea Region. Main reasons of increasing drought effect are global warming, overgrazing, conversion of grassland and forest areas into croplands and increased erosion in Turkey. Grassland area in Turkey was 38.9 million ha in 1949 and this area had been decreased to 28.3 million ha till 1969 and today is 21.8 million ha. While agricultural land area was 8.5 million ha in 1935, it increased to 25 million ha in 1970 and today it is 28 million ha. Meanwhile forested land area had been decreased up to 2.6 million ha from 1950 to 1997. In Turkey, drought tolerant ecotypes of important timber species need to be selected in order to reduce the potential effects of global warming on tree mortalities. Additionally, drought risk maps of forest areas should be prepared to determine drought risk assessment and take necessary measures. Drought can further accelerate the effects and extent of erosion. Therefore, it is also important to account the effects of erosion on the productivity of agricultural and forest goods. Finally, effects of global warming need to be incorporated into afforestation strategies of Turkey.

The study called Erosion and Precautions in Alt'napa Dam Basin (Konya) aims to reveal the relationship between erosion and the geographical factors that cause the erosion in the region. The Alt'napa Dam Basin is located in the west of the city center of Konya. In Alt'napa Dam Basin plateau and valley basin plains form the main relief. In the basin, the Upper Miosen-Pliosen old clayed limestones, marls, and tuffs occupy a large area. The semi-arid climate, in which the spring and autumn rains are effective, is seen in the research area. The vegetation cover is poor. Generally, step formations, which can withstand more heat and drought, are more common. Ulucay river and river's reaches have been influential in shaping the basin. Besides the natural geographical features of the Altınapa Dam Basin, wrong land use, overgrazing, neglect such as forest degradation have been effective in the erosion and severity of erosion. Water erosion and its types are observed in the area. In the eastern, northern and southern parts of the research area, there is a wide area that is affected by severe and very severe erosion. The mild to moderate severe erosion has been effective on the slopes of the valley basin with different elevations. The negativity of the natural and human conditions in the Altınapa Dam Basin caused continuation of the erosion. One of the measures that can be taken in this regard is the planting measures and raising the awareness of the local people about the land use. [ABSTRACT FROM AUTHOR]

The surface irrigation methods are commonly used to apply crop water requirement in our country and the world. The runoff losses decrease irrigation efficiency and caused soil losses, especially at furrow irrigation. Furrow rate and length are important parameter for water and soil losses and are determined depend on the soil texture and slope. Although many studies on the length of the furrow; there are significant shortcomings in the determination of non-erosive flow rate. Generally flow rate is determined as a function of only the slope; but it can be varied by the soil texture, aggregate size and stability, infiltration and water advance features. In this study, different methods will investigate to determine non-erosive flow rate with using furrow geometry and flow velocity. As a result of evaluation of literatures, field observations and secondly semi-empirical method with the using more field data are recommended. For this aim maximum acceptable flow velocity was accepted as 0.13-0.17 m.s-1 for erosive soil, and 0.22-0.25 m s-1 for more stable soils. In this way, optimal flow rate using will contribute to more efficient water use and conservation of water and land resources. [ABSTRACT FROM AUTHOR]

The erosions and ulcers located on mucous membranes of oral cavity are complaints encountered frequently in our clinical practice which directly affect the life quality of patients. These lesions may be first signs of a disease with high mortality risk or presenting sign of a multisystemic disease or a cancer. Consequently, the erosions or ulcers of oral cavity are important lesions which need careful and detailed clinical evaluations. In this article, it was focused on algorithmic differential diagnosis of the diseases causing oral ulcers. (Turk derm 2012; 46 Suppl 2: 77-85) [ABSTRACT FROM AUTHOR]

Aim: To investigate the main problems faced by patients undergoing artificial urinary sphincter (AUS) implantation and the important factors that the surgeon should take into consideration in predicting these problems. Postprostatectomy incontinence continues to be a complication that most severely impairs the quality of life. Materials and methods: Of 82 initial patients, 64 patients with complete data who responded positively to the invitation for examination were divided into 3 groups: patients with implant-tissue interaction, patients with no problems, and those with mechanical failure. Univariate analysis, Student's t-test, Pearson's chi-square test, logistic regression, and Kaplan-Meier analysis were used in this study. Results: Of the 64 patients, 20 (31.2%) were reoperated on with a mean follow-up of 62 (range: 1-120) months. It was found that the risk of urethral erosion was higher in patients with obesity (P = 0.04), diabetes (P < 0.0001), radical prostatectomy (P < 0.0001), and adjuvant radiotherapy (P < 0.0001), and in those with the suspicion of urethral stricture who would undergo sphincter implantation within at least 3 months after the latest surgical treatment of urethral stricture, compared to other patients (P < 0.0001). Additionally, we found that surgical experience also had a strong effect on the risk of urethral erosion.
