    Morphological Analysis of Büyük Menderes River Over the Years Using Satellite Imagery
    (IAHR-Int Assoc Hydro-Environment Engineering Research, 2023) Bor, Asli; Hazar, Oguz; Elci, Sebnem
    Both bank erosion and sediment deposition on the inner margins are important watershed management problems for streams. Bank erosion not only causes the loss of agricultural lands, but also leads to the narrowing of the cross sections of the streams with the accumulation of sediment in the interior, resulting in floods, damage to the cultivated areas, reduction in dam reservoir lifespan and thus, serious damage to a country's economy. In this study, the morphological analysis of the B. Menderes River, which is one of the most important rivers of Turkey and a residential and intensive agriculture region, for the thirty-year period between 1990-2020 is made via utilization of QGIS for the analysis of Landsat satellite images. This study is thought to be a preliminary study to quantify the morphological changes in B.Menderes River and is expected to be a basis for linking these changes to the changes in the hydrological regime in the basin. During this analysis, the shoreline of the main river, approximately 570 km long, was divided into 10 segments and the sinuosity index values, which are fold parameters, were calculated for each segment. According to the study, it is found that the curvature of the meanders of the B. Menderes River varies between 1.5 and 2.5 in most places.

    Water Quality Evaluation Using Various Water Quality Indices: a Case Study for B. Menderes River, Turkey
    (International Association for Hydro-Environment Engineering and Research, 2022) Bor, A.; Elgi, Ș.
    Water quality is an important factor for public health and aquatic life, and it has become an increasingly important problem due to the growth ofthe population, urban expansion, and development. Forthis reason, the evaluation of surface water quality is an important issue for countries. Water quality indexing is widely used to present complex water quality data in a more comprehensible form and provides decision-makers and non-technical managers ofwater resources with concise information about water quality status. In this study, the water quality is determined based on the water quality monitoring data obtained from the Kocarli Bridge gauging station in the B. Menderes Riverforthe 9 years period between 2006 and 2014. The main pollutants in this region, with parameters exceeding border limit values PH were found to be Sulphate (S04), Nitrate (N03), Ammonia (NH4), Nitrite (N02), Phosphate (P04), Electrical Conductivity (EC), Total Dissolved Solids (TDS) Calcium (CA), Magnesium (MG), Sodium (Na), Potassium (K) and Bacteriological Parameters (E-coli, F-Strp, and Total Coli). In addition, five different WQI performances are compared so that the data can be easily interpreted. The methods used were the weighted arithmetic index (WAI-WQI) Environmental Water Quality Index (CCME-WQI) Canadian Council of Canada (CCME-WQI), Universal Water Quality Index (UWQI), Oregon Water Quality Index (0WQI), and Aquatic Toxicity Index (ATI). The applicability of different methodologies is discussed, and significant inconsistencies were observed between the classification results. © 2022 IAHR.
