Field studies of river flow dynamics in the lower pool of a hydrosystem

Results of field studies of Istra River current dynamics over a 35-km reach in the lower pool of a hydrosystem are analyzed. Data on the distribution of current velocities in cross-sections with different morphometry and the characteristics of bottom deposits at significantly different water discharges, and data on variations in the water surface slope are presented. The coefficients of hydraulic friction are assessed.     

Dynamics of the coastal zone of the Kuibyshev and Saratov reservoirs in the Tolyatti area and its correlation with the operation regime of the Zhigulevskaya HPP

The negative effect of vibrations of the spillway dam of the Zhigulevskaya HPP on the oscillations of soils and shore deformations near Tolyatti Town is demonstrated on the basis of field observational data.     

Glacier Revival and Advances in the Period of Global Warming

Surges of the Pamir Glaciers in the First 20 Years of the 21st Century

Doklady Earth Sciences - The activation of surging glaciers in the Pamirs over the past 20 years has been studied. Glacier surges occurred in the basins of the Surkhob, Muksu, Sauksai, Seldara...     

Cascades of subglacial lakes in Antarctica

Progress in understanding cascades of subglacial lakes in Antarctica and in the dynamics of their surface was derived using satellite laser altimetry measurements ICESat. The morphological and dynamical signs indicate subglacial lakes and the positions of their shore lines. Oscillations of surfaces in transition zones are periodic, while the changes in surface elevation above subglacial lakes are random. The pattern of surface displacements above cascades of subglacial lakes in Antarctica and their transition zones as similar. In the sense of technology, this paper initiates the method of mapping subglacial lakes based on satellite laser measurements of elevation.
