Earthen levees are commonly used protective structures against seasonal flood activity. Monitoring of the embankments condition is an important issue related to the protection of people's lives, their property, environment and infrastructure. The assessment of the physical condition of the levee can be obtained by comparison of the sensors measurements? localized within the embankment and the changes in parameters values obtained as a result of numerical modelling of flooding process. Uncertainty of the values of ...

The accuracy of location of seismic sources using time reversal imaging techniques is considered in this article. The location procedure is performed using backpropagation of the recorded and reversed seismic signal from receiver throughout assumed geological model. The new imaging parameters, peak average power ratio (PAPR) coefficient is used for efficient visualization of the backpropagation of the seismic energy. The detection of seismic wave focusing was carried out on the basis of the high PAPR parameter val...
