| Research Abstract |
Landform changes in lake-catchment systems may give a great insight into clarifying the relationship between geomorphic processes and geomorphic histories. Tracers and dating tools for mass movement(Cs-137 and Pb-210_<exc>) are inevitable in these studies. Changes in physical properties and Pb-210_<exc> concentration of sediments are closely related to geomorphic changes. Cs-137 concentration in surface layers is connected to surface erosional processes and Pb-210_<exc> and Cs-137 of lake sediments are available for sediment dating. Short-term observation and analyses in the systems reveal some relationship between the processes(heavy rainfall event, earthquake, etc.) and sediment information, suggesting clues to find long-term causal relations in land form evolutions.
