M. Davoodi and M. Razzaghi, M. K. Jafari,

There is a worldwide interest in the proper design of embankment dams to resist earthquake loadings. For the first time in Iran, a complete ambient vibration survey due to low-level loads such as wind, machinery activities, low level tectonic activities, and water exit from bottom outlet was performed on Marun embankment dam. These kinds of ambient vibration tests are suitable for manifesting t...

The objective of this study was to investigate how the earth dam is destroyed due to the effect of upstream and downstream slope of the body in overflow conditions. Therefore, eight models were provided that each model is constructed from the embankment dam with different upstream and downstream slopes (1:1, 2:1) and the soil properties (Sc) on breach formation. The time and method of dam break...

This study aims to assess the characteristics of humic acids (HAs) in floodplain soils. HAs were isolated from Fluvisols located out embankment riparian forest (unflooded forest) and within (inter-embankment), area periodically flooded. these soils examined for quantity, structure, humification degree using extraction methods as well elemental analysis, UV-Vis, FTIR, EPR, 1HNMR spectroscopies. ...

Abstract A summer polder had developed a deficit in surface elevation of about 20 cm respect to rising sea level during its almost one-hundred-year period embankment. We addressed the questions whether distance restored site intertidal flats and continuation livestock grazing could hamper surface-elevation change first 10 years after de-embankment polder. The showed similar positive linear rela...

In this paper, we study a task of slope collapse detection (SCD) for river embankment and formulate it as the tasks motion image recognition. Specifically, introduce an SCD method based on recognition technologies to help inspector attendants detect collapse. method, use foreground algorithm identify scene embankment. Since moving targets in may not only be but also maybe some biology, further ...

Abstract The objective of this study was to investigate the effectiveness soil–cement (SC) columns, provided either individually or in combination with lime on stability embankment constructed soft consolidating soil. evaluated terms both settlement and factor safety at various time intervals during consolidation. columns studied numerically using two-dimensional plane strain finite element met...

Abstract The article presents the process of creating a computational model for stability analysis harbour wharf’s embankment with regards to its failure. described elements that were taken into account at stage data preparation are: historical structure (structural calculations, and calculations embankment), results author’s own soil material tests (concrete, steel), environmental conditions (...

Abstract Safety and maintenance of railway tracks has been very crucial, for sustainable economic development many nations. Almost the entire Indian were built over raised earth embankments. These embankments are susceptible to slope failure due numerous reasons. One major cause is seepage surface runoff during rainy (monsoon) season. Erosion by gullying regarded as most significant scar. Vario...
