A process of the removal of dissolved elements in the ocean by adsorption onto settling particulate matters (scavenging) is studied analytically and using the Lagrangian and Eulerian numerical methods. The generalized model of scavenging in a multico

It is known that Flux Corrected Transport algorithms can produce entropy-violating solutions of hyperbolic conservation laws. Our purpose is to design flux correction with maximal antidiffusive fluxes to obtain entropy solutions of scalar hyperbolic

Our goal was to develop a robust algorithm for numerical simulation of one-dimensional shallow water flow in a complex multiply-connected channel network with arbitrary geometry and variable topography. We apply a central-upwind scheme with a novel r

There are two partially linked risks to the Kyiv city associated with the Dnieper river: (A) risk of the inundation of the urban coastal areas during the extremely high floods or due to the break of the Hydropower Plant dam located upstream Kyiv, and

The measurements of 137Cs concentration in the rivers of Fukushima prefecture demonstrate the more significant role of the fluxes of 137Cs adherent to the suspended sediments in comparison with the rivers contaminated after the Chernobyl accident. Th

The coastal areas of three nuclear power plants (NPP) in the Tohoku region of Japan were impacted by the tsunami waves of the earthquake on 11 March 2011. The overtopping of the tsunami protective dikes of Fukushima Daiichi NPP and inundation of the

The shallow water flows in coastal areas of seas, rivers and reservoirs are simulated usually by 2-D depth averaged models. However, the needs for fine resolution of the computational grids and large scales of the modeling areas require in practical

Flux-corrected transport (FCT) is one of the flux limiter methods. Unlike the total variation diminishing methods, obtaining the known FCT formulas for computing flux limiters is not quite transparent, and their transformation is not obvious when the

The Hydrological Dispersion Module of JRODOS was implemented for the predictions of the long term dynamics of radiocesium in the rivers and ponds of the Fukushima Prefecture and for the forecasting of radiocesium dynamics in the reservoirs under the
