W pracy przedstawiono analizę stateczności wałów przeciwpowodziowych, zlokalizowanych przy Moście Kotlarskim w Krakowie, przeprowadzonej w oparciu o modelowanie numeryczne. Uwzględniono dynamicznie zmieniające się położenie zwierciadła wody w Wiśle pomiędzy stanami charakterystycznymi dla powodzi dziesięciolecia a pięćsetlecia. Opisano metodologię przeprowadzonej analizy wraz z omówieniem wyników.

Geoinżynierska ocena ochrony przeciwpowodziowej szpitala w Słubicach
(Wydawnictwa AGH, 2011) Kołodziejczyk, Urszula
The extreme river water stages cause intensive seepage on flooded area, normally protected by levees. The example of this is town Slubice (Lubuski District), situated in 2 m lower than alarm water level. The paper describes the geoengineering opinion relating the quality of embankments in Slubice focused on the intensivity of water percolation from Odra bed to the terrains outside levees, where the hospital is situated. The modernization in 1999 limited, but not eliminated, the water percolation through the banks and, due to financial deficiency, did not included the proper condensation of subsoil and the body of banks, where, as it was proved by geotechnical analysis, still remain parts of soil of loose or average structure and parts of soil rich in organic matter. New flood protection solutions in Slubice are necessary and as long as they are not become realized, the town would fight against the excess of water percolating from Odra river bed.

Lubuski odcinek Odry - analiza stanu technicznego lewostronnego obwałowania rzeki Odry w km 432,60-442,80
(Wydawnictwa AGH, 2011) Asani, Anna
This article presents the results of the technical condition study of the embankments located on the left bank of the Oder river, at 432.60-442.80 km river section. It is a second class embankment, a length of 12.0 kilometres, which protects the following towns: Nowa Sól (Pleszówek), Koserz, Modrzyca, Otyń and Bobrowniki together with adjacent areas of agricultural crops. The scope of works was consistent with the standards and included: fieldwork (stocktalking, probing with DPL probe and small-diameter drilling), laboratory tests (to determine the leading parameters of soil: soil type, bulk density, humidity, degree of plasticity, filtration factor, the organic content, etc.) and assessing the technical condition of the embankment as for its effective flood protection. The studies indicate that the embankment is generally in the medium condition, and primarily the repair of embankments should be carried out in the most vulnerable parts of the landslide, ie at km 0+200-1+050 km 1+550, km 2+450 and km 5+330.

Problemy analizy stateczności skarp nasypów kolejowych
(2008) Batog, Andrzej; Hawrysz, Maciej
In the paper the problems of the slope stability analysis in case of the railroad embankments were presented. There was outlined the current design approaches and codes did not consider the scale of dynamic effects which will appear after the train's speed increase to 160 km/h and over. The design procedure of load determination caused by the trains running at the speed 120 km/h and over was presented and the appropriate design approach for slope stability analysis for those speeds was proposed.
