Abstract
Su kaynakları yönetimi, dünyadaki en önemli konular ve sorunlardan biridir. Bu yönetim, kalite yönetimi veya su kaynaklarının kantitatif yönetimi şeklinde olabilir. Su kaynaklarının kalite yönetimi büyük önem taşımaktadır. Bu durumda önemli problemlerden biri, su bir baraj haznesine veya göle aktığında girdi akışının (örneğin bir nehir) nasıl davranacağıdır. Giriş akımının hazneye / göle dağılımı; giriş debisi, giriş derinliği, hazne çıkışının konumu ve tipi, giriş sediment tipi, giriş akımının sediment konsantrasyonu ve hazne / göl vb. Gibi önemli parametrelere bağlıdır. Bu nedenle, Bahsedilen parametrelerin her birinin haznedeki veya göldeki dağılım üzerindeki bu etkisi incelenmelidir. Henüz çalışılmamış önemli bir parametre, giriş akımının sıcaklığının ve onun etkisi hazne / göldeki giren suyun dağılımı üzerindeki etkisidir. Bu amaçla, bu çalışmada FLOW3D hesaplamalı akışkanlar dinamiği yazılımı seçilmiştir. Su sıcaklığının ve askıdaki sediment konsantrasyonunun hazne / göllerdeki giren akımın dağılım şeklinin üzerindeki etkisi dikkate alınmıştır. Farklı su sıcaklığı ve askıdaki sediment konsantrasyon değerleri ile çeşitli simülasyonlar yapılmıştır ve sonuçlar değişik durumlar için birbirleriyle karşılaştırılmıştır. Sonuçlar, su sıcaklığının sediment parçacıkları dağılımı üzerindeki yüksek etkisini göstermektedir.

Numerical Study on Suspended Sediment Transport under the Effect of Water Temperature in Reservoirs and Lakes
Abstract
Water resources management is one of the most important issues and challenges in the world. This management may be in the form of quality management or quantitative management of water resources. Quality management of water resources is of great importance. A major problem in this case is how the input flow (for example a river) will behave when water flows to a dam reservoir or lake. Distribution of the input stream to the reservoir/lake depends on important parameters such as inflow discharge, input depth, situation and type of the reservoir outlet, type of inlet sediment , sediment concentration of inflow current and reservoir/lake , and etc. Therefore, this effect of each of the mentioned parameters on the distribution in the reservoir or lake should be examined. An important parameter that has not yet been studied is the effect of temperature of the inflow current's and the reservoir/lake's water on the distribution. For this purpose, the FLOW3D computational fluid dynamics code was selected in this study. The effect of water temperature and concentration of suspended sediment on distribution in reservoirs/lakes is considered. Several simulations with different water temperature and suspended sediment concentration values were done. Results are shown and compared each other. The results indicate the high effect of water temperature on distribution of sediments.
