IntroductionSediment is described as solid particles generated by the disintegration process of organic and inorganic materials (Bortone, 2006). These particles, found in various shapes and sizes, can be transported by water, wind, glaciers, and other natural causes (Montgomery et al., 2000). Sediment deposited in deltas and reservoirs are generally fine-grained (sand, silt, and clay) (Kamarudin et al., 2009;Tigrek and Aras, 2011). The sedimentation process depends on the flow regime and flow rate of the river (Kamarudin et al., 2009). Natural rivers are considered balanced with respect to sediment and water inflow and outflow. However, when rivers are controlled, especially by the construction of large dams, this balance can be dramatically changed (Morris and Fan, 1998). The alteration of the natural flow regime leads to changes to the hydrological, geomorphological, and ecological conditions both upstream and downstream (Galay, 1983;Graf, 2006;Magilligan et al., 2013;Csiki and Rhoads, 2014;. Dam construction in rivers decreases velocity, causing a sedimentation increase upstream of the dam. This reduces the storage capacity of reservoirs, thus negatively influencing other benefits of large dams, such as water supply, power production, and flood control (Morris and Fan, 1998). Sedimentation can change geomorphological conditions upstream of reservoir areas. For example, sediments deposited along riverbanks due to reduced flow will narrow the cross-section of a river before it reaches the reservoir, while the accumulated sediments can change the terrain of the bottom of the reservoir (Ryan, 1991;Csiki and Rhoads, 2014). Changes in the amount and composition of sediment, carrying

“…However, a contrast was found for the composition of the sand fraction that was associated with a high percentage of quartz. The changes in the relative abundance of minerals in fine fractions have been used to reveal the earth surface processes (Haldar & Tišljar, 2014;Montgomery et al, 2000;Nicholas, 1997;Viers et al, 2007). A change in relative intensities of peaks of the minerals was recognized along with the new peak X-rays diffractograms.…”

Glaciated sediments are a significant source to know the glacier environment processes. Glacial meltwater streams draining from the Himalayan glaciers carry with a different type of sediment sizes, because of the supraglacial, englacial, and subglacial debris, as well as formation of sediments from erosion by the movement of the ice. This study examines mineralogical and textural characteristics of sediments transported in the selected Indian Himalayan glacier meltwater streams. The results indicate that various sedimentological diversity occurring within proximity of active glaciations due to glacio-hydrological processes. Sedimentological and mineralogical characteristics suggest that sediments of the proglacial area are polygenic in nature. A comparative change in feldspar/quartz among bedrock, sand, and clay suggested that the active geochemical weathering regime at a low-temperature environment maturing the sand composition. The less clay fraction in glacier sediment indicates limited generation of clay minerals in the glacier environment. Change in clay composition from supraglacial moraine to proglacial environment indicated a chemical alteration in glaciated valley assisted by low slope glacio-fluvial environment.

Farklı şekil ve büyüklükte olan bu parçacıklar su, rüzgâr, buzul ve diğer doğal etmenlerle taşınabilmektedir (Montgomery et al 2000). Delta ve rezervuarlarda biriken sedimentler genellikle ince tanelidirler (kum, silt ve kil iriliğinde) (Kamarudin et al 2009;Tigrek ve Aras 2011).…”

ÖzetErozyon sürecinin bir sonucu olarak ortaya çıkan sedimentler bozulmuş topraklara gösterilebilecek en güzel örneklerden biridir. Bozulmuş toprakların restorasyonu ve üretim potansiyellerinin yeniden yükseltilmesi amacıyla organik materyal uygulaması son zamanlarda sıklıkla kullanılmaktadır. Sera koşullarında yürütülen bu çalışmada çay posası ve ahır gübresi uygulamasının sedimentlerin bazı kimyasal özellikleri üzerine etkileri incelenmiştir. Bu amaçla sedimentlere farklı oranlarda (%0, %2.5, %5, %7.5, %10, %12.5 ve %15) çay posası ve ahır gübresi ilave edilerek 18 hafta süreyle inkübasyona bırakılmıştır. İnkübasyon süresi sonunda organik madde, toplam karbon, toplam azot ve toplam kükürt içeriklerinin çay posası uygulanan sedimentlerde önemli seviyede yüksek olduğu bunun yanında söz konusu özelliklerin organik materyalin uygulama oranına bağlı olarak artma eğiliminde olduğu belirlenmiştir. Sedimentlerin pH değerlerinin ise çay posası uygulamasında daha düşük olduğu ve uygulama oranlarına bağlı olarak çay posasında düşme ve ahır gübresinde ise yükselme eğiliminde olduğu ortaya konulmuştur.Anahtar kelimeler: Ahır gübresi, çay posası, inkübasyon, organik madde uygulaması, sediment AbstractSediments as a result of the erosion process is one of the best examples that can be shown to degraded soils. In order to increase production potential and restoration of degraded soils, organic matter addition have been used in the recent years. This study was conducted to investigate changes on some chemical properties including organic matter content, total carbon, nitrogen and sulphur contents and pH after the tea waste and farmyard manure addition to the sediments in greenhouse condition. For this purpose, different amounts of tea waste and farmyard manure (0%, 2.5%, 5%, 7.5%, 10%, 12.5% and 15%) were added to sediment samples and left for incubation of 18 weeks. Statistical analyses showed that the organic matter application caused improvement in the examined properties of the sediments and this improvement tended to increase depending on application rates. The pH of the sediments were lower in tea waste application and it was found to have a tendency to decrease depending on application rates, while it was revealed that pH increased depending on application rate of farmyard manure.
