Flood creates the most complex problems of engineering hydrology and extreme flood contains the crucial risk for urban areas, infrastructure, industry and agriculture. The aim of this paper is to study the transient flow caused by flood for levee of Filyos River. Numerical modeling based on finite element method was performed in the analyses. PlaxFlow which is an add-on module to Plaxis 2D, is used for the time variation of seepage in several points of interest within the levee. Exit velocity at several points of interest within the levee and degree of saturation of levee and hydraulic gradient were investigated. In addition, under seepage of water through different soil types underneath Filyos levee was examined. The results of transient flow analyses when piping occurred and sand boil formed were presented for different soil types.

Taşkın, mühendislik hidrolojisinin en karmaşık sorunlarını meydana getirir ve aşırı taşkın, kentsel alanlar, altyapı, sanayi ve tarım için hayati riskleri içerir. Bu makalenin amacı, Filyos Nehri seddesi üzerinde taşkınların neden olduğu düzensiz akışı incelemektir. Analizlerde sonlu elemanlar yöntemine dayalı sayısal modelleme yapılmıştır. Plaxis 2D'ye bir eklenti modülü olan PlaxFlow, program dahilindeki çeşitli ilgi noktalarında sızıntının zaman değişimi analizi için kullanılır. Seddenin çeşitli ilgi noktalarında çıkış hızı, hidrolik eğim ve doygunluk derecesi incelenmiştir. Ayrıca Filyos seddesinin altındaki farklı zemin türleri için su sızıntısı da incelenmiştir. Borulama meydana geldiğinde ve oluşan kum kaynamasında meydana gelen düzensiz akış analizlerinin sonuçları farklı zemin tipleri için sunulmuştur.
