Energy estimation of talus creep slopes of mountain glacier basin of the Aktru River headwaters

The talus dynamics accumulation of the mountain glacier of the Aktru River basin (south-east of the Altay Mountains), located at the declivity of diverse exposure and intercoupling the talus creep with the power of active layer, has been analysed using the energy approach. The obtained data testify that the velocities of the material motion composing taluses, is connected with fluctuations of the energy amount entering into the system from the environment and its transformations in the denudation process. In the article the method for energy features description of talus creep slopes is described, which fully reflects the system element interaction between itself and with the environment. Thus, the material motion of taluses is mostly observed during the warm time period that reduces the increase of the active layer capacity. At the same time, the energy consumption on friction and traction power decreases during talus creep. Consequently, the velocity of debris motion grows up and can cause catastrophic patterns. This approach allows calculating the denudation rates at different natural complex that are provided by one or a group of processes; defining the energy stability of a geomorphosystem; and forecasting the behaviour of any geomorphosystem
