The paper investigates the performance of altimetric satellite instruments to detect river ice onset and melting dates and to retrieve ice thickness of the Ob River. This is a first attempt to use satellite altimetry for monitoring ice in the challenging conditions restrained by the object size. A novel approach permitted elaboration of the spatiotemporal ice thickness product for the 400 km river reach. The potential of the product for prediction of ice road operation was demonstrated.

As climate change completely restructures hydrological processes and ecosystems in alpine areas, monitoring is fundamental to adaptation. Here we present a database on more than 10 years of hydrometeorological monitoring at the Djankuat station in the North Caucasus, which is one of 30 unique world reference sites with annual mass balance series longer than 50 years. We hope it will be useful for scientists studying various aspects of hydrological processes in mountain areas.

Study of hydraulic and channel changes the Lena River near city Yakutsk was done using STREAM_2D two-dimensional hydrodynamic model (author V. Belikov et al.). Channel changes forecast has shown that degradation of the Adamovskaya branch will be continued, which is the most negative impact for the Yakutsk city. However, to the end of the 10-year forecast period the equal distribution between Adamovskaya and Buorylarskaya channels is possible.

Two-dimensional hydrodynamic STREAM_2D model have been applied to the confluence of Amur and Zeya rivers. Main flow characteristics and possible channel changes are considered during modeling for two scenarios – without dams near Big Heihe Island (1) and with four dams in the side channels around the island (2). Results of modeling demonstrate impact of dams construction on flow concentrating in the main channel, which can lead to increasing of flow velocities and subsequent erosion in main Amur

Inundations on the Black Sea coast of the Krasnodar territory of the Russian Federation were analysed for 1945 to 2013. Risks, hazards and damage from inundations here are some of the highest in the country. The large quantity and the extremeness of rainfall, and the intense flood regimes of the rivers are the main contributors. Additionally, anthropogenic impact such as badly planned economic activities in channels, floodplains and on river watersheds strongly enhance the effects.
