The Role of Water and Weathering Processes in Landslides in Hungarian Loess Sediments

Loess-paleosol bluffs can be unstable, but in the course of urbanization, houses may built such locations to take advantage view. One factor affecting stability is water, role which mass movements well established. In this study, connection meteorological conditions, as rainfall and subsequent water level changes, was researched using new statistical methods. The periodicity Danube analyzed wavelet spectrum analyses, while changepoint analysis used determine variations quantity precipitation. These results were compared chronology six Kulcs, Hungary. This study also focused on changes geochemical properties loess different weather conditions (dry periods, wet flooding). showed that only two connected hydrological other case human activity have been factors. models created PHREEQC calcite kaolinite precipitation, albite dolomite dissolution main mineral over a year. Albite found dissolve precipitation significant during flood periods.
