Bu çalışmada, yatay yönde yer sarsıntısına maruz kalan prizmatik bir tankta gerçekleşen çalkalanma modellemesi düzgünleştirilmiş parçacık hidrodinamiği yöntemiyle (SPH) gerçekleştirilmiştir. SPH yöntemi sonuçları bir deney ve ANSYS Fluent modeli sonuçlarıyla doğrulanmıştır. Deneyden ve Fluent modeliyle elde edilen çalkalanma profilleri burada ele alınan SPH yöntemi sonucuyla müthiş bir uyumluluk göstermektedir. Bu çalışma irdelenen SPH yöntemi, süreksizlikleri yakalama ve hareketli sınırları ele almada oldukça etkilidir.
