STREAM_2D software package was applied to retrospective and predictive simulations of the Lena River near city Yakutsk hydraulic and channel changes during ice-free period. The modelling results indicate significant correspondence of simulated water discharges distribution and water levels with observed one, model has captured main erosion and accumulation zones observed in the 2009–2016 years. Runoff hydrographs from the ECOMAG runoff model simulations based on the data the global climate model MIROC-ESM-CHEM with daily time step for two climate scenario rcp2.6 and rcp8.5 were used as input into hydrodynamic model. Comparison of scenario, based on modern hydrographs and two scenarios, based on climate projections, have shown the changes in the range of channel-forming discharges and their duration. By the results of 20-year simulation of channel evolution for tree scenario, the position of the main areas of erosion and deposition under scenario rcp2.6 and rcp8.5 retained the same as under modern scenario, but some additional new local areas of erosion during peak flows near the banks can be formed. Erosion can increase by up to 1 - 2 meters and even more in some areas, but due to the reduced duration of channel-forming flood discharges, the shifting of some large erosion-accumulative forms is slower than in under the scenario, based on the modern hydrographs.

Comprehensive data on natural hazards and their consequences are crucial for effective for risk assessment, adaptation planning, and emergency response. However, many countries face challenges with fragmented, inconsistent, and inaccessible data, particularly regarding local-scale events. To address this data gap in Russia, we developed an end-to-end processing pipeline that scrapes news from various online sources, ...

Cloud shadows lead to alternating light and dark periods at the surface, with
the most abrupt changes occurring in the presence of low-level forced cumulus clouds.

We examine the physical and biological responses of forest canopies to step changes in light
caused by passing low cumulus clouds that intermittently block the direct solar beam. Using
data obtained at a tropical rainforest and at a midlatitude deciduous forest, we estimate the
course of sensible heat flux, net ecosystem exchange, evapotranspiration, and water-use efficiency in response ...

We examined the net-ecosystem-exchange (NEE)-based annual carbon-balance estimates
obtained from eddy-covariance (EC) measurements at an unmanaged sedge-grass marsh
ecosystem (Tˇreboˇn, Czech Republic, 49°1′ N, 14°46′ E), seeking methods to improve the EC
measurements in inhomogeneous environment. The data filtering procedure was developed
using three thresholds: (a) a stationarity test; (b) a stability u∗-threshold; and (c) a high relative
humidity RH-threshold. ...

Carbon dioxide (CO₂) efflux from soil (or soil respiration, SR) is one of the most important yet variable characteristics of soil. When evaluating large areas, CO₂ efflux modeling serves as a viable alternative to direct measurements. This research aims to identify site-specific differences and their effects on empirical CO₂ efflux modeling. The experimental data from ...
