Study of Behavioral and Performance in Maroon Rockfill Dam with using Instrumentation in Operation Period

Ensuring proper behavior of rockfill dams in several conditions such as during construction, dewatering and operation with considering serious damages due to failure of the dam and existence of multiple uncertainities in basics, assumptions and design parameters of dam is important object and inevitable. Main idea of this paper is study of behavioral dams with using instrumentations. Maroon rockfill dam is located in 19 kilometers of behbahan city in Khuzestan province. This dam with 165 meter heigth is one of the high dams in Iran. In this research in five years of operation period behavioral of Maroon dam was performed. With considering numerous data of instrumentations in dam with design diagrams for important parameters such as settlement, pore water pressure, total stress, strain and water leakage behavior of dam was evaluated.
