“…Additionally, the temperature is fixed at a constant value (ground temperature) on the lower edge of the model. The temperature on the upper edge is set at 1 h intervals to the air or water temperature (depending on the water level) [3,11].…”

This article presents a method of the stability assessment of the experimental flood embankment used in the ISMOP project. Simultaneous conduction of numerical modeling using Itasca Flac 2D 7.0 software and real performed flood experiments allows for a detailed analysis of the state of flood embankment stability. The aim of the article is a presentation of similarity assessment between numerical models and a real performed flooding experiment using an aggregate moving window and L1-norm. By evaluating these similarity measures, numerical models with greater resemblance to real data from a flood embankment are chosen. On this basis, the embankment stability state is evaluated. In addition, the purpose of this article is also to present the results of the performed tests between those gathered in the database numerical models and a real flooding experiment from a full-size earthen flood embankment with built-in sensors built in Czernichow, Poland.

“…Some preliminary measurements, including infrared imaging, were made on small experimental embankment (built in scale 1:5, without grass on its surface) before the large experimental embankment was built. Analyzes of the filtration process, numerical models and infrared imaging proved that infrared monitoring is useful in detecting the water leakages in such soil embankment [5,6].…”

The interpretation of continuous thermographic measurements of leaking soil embankment is presented in the abstract. The measurements were conducted at the daybreak and sunny morning, when air temperature rose intensively. The temperature of leak regions has increased slowly in contrary to temperature of dry one regions. Examining differential thermal images taken with one-hour delay, it was possible to detect the horizontal zone where the sand layer was located and water filtration on embankment surface existed.

“…The results of numerical calculations were compared with the results of field measurements inside of an experimental water storage facility, which was built under the ISMOP Project (IT System of Levee Monitoring) [7][8]. The study is based also on results a few experiments conducted under the project [9][10][11][12].…”

Abstract. The article discusses the potential for using numerical simulation to assess the development of deformation and pore pressure changes in a levee as a result of the increase and decrease of the flood wave. The simulation made in FLAC 2D did not take into account the filter-erosion deformation associated with seepage in the levee. The simulations were carried out for a field experimental storage consisting of two combined levees, which was constructed with the help of homogeneous cohesive materials with different filtration coefficients. Calculated and measured pore pressure changes were analysed at 4 monitoring points. The water level was increased to 4 m in 96 hours and decreased in 120 hours. The characteristics of the calculated and measured pore pressure changes over time were similar. The maximum values of the calculated and measured pore pressure were almost identical. The only differences were the greater delay of the experimental levee response to changes in water level increase compared to the response of the numerical model. These differences were probably related to filtering-erosion effects during seepage in the levee.
