Abstract

This study shows hill slope process of Mt. Ovoot in the northeast of Khangai Mountain Range, Mongolia. This work is mainly focused on sediment transportation by surface and subsurface flows in Mt. Ovoot based on movement of microelements within soil profiles along the mountain slopes and measurement of particle sizes and shapes of the soils. The main purpose is (1) to determine the chemical and physical properties of soils, and (2) to reveal hill slope process with movements of microelements. Movement of the microelements show intensive slope processes in the Mt. Ovoot.
Each surface soil on upper slope contains microelements less than those on lower slope of the mountain, where sediments have been more round and finer. It infers that more soils are eroded and accumulated on upper and lower slopes, respectively, these transport and deposition of the soil particles are caused by the surface and subsurface flows.
