Numerical Modeling of the Anthropogenic Dust Transfer by Means of Quasistatic and Non-Quasistatic Models
No full textKinematics of the anthropogenic dust propagation emitted into the atmosphere by big cities and separate sources using numerical integration of the system of three-dimensional non-linear quasistatic and non-static equations of atmosphere hydrothermodinamics and equation of dust transfer-diffusion in the atmosphere are studied. It is obtained through modeling that kinematics of a dust propagation obtained by quazistatic and non-static equations have both common and different features. In case of beta- mesoscale diffusion, which is described by means of quazistatic equations, advective diffusion plays the key role in the dust transfer process of. In case of gamma- mesoscale diffusion, which is described by means of non-static equations, the major role in the process of dust transfer, is played by convective diffusion
Numerical Modeling of PM2.5 Propagation in Tbilisi Atmosphere in Winter. I. A Case of Background North Light Wind
No full textPM2.5 propagation at Tbilisi territory in winter period in case of background north light wind is numerically modeled and analyzed through combined integration of 3D regional model of atmospheric processes evolution and equation of admixtures transfer-diffusion. Motor transport moving at city streets and trunk lines is a main source of atmosphere pollution. There are investigated the main peculiarities, which characterize the process of microaerosols spatial distribution under rugged terrain conditions. PM2.5 high concentration zones are established at the territory of city, time intervals, when high air pollution forms or air self-purification takes place, are determined. Temporal and spatial variations of PM2.5 concentration in the lower part of atmospheric boundary layer are studied. It is established that 25 mkg/m3 and higher concentration is obtained from 11AM to 1PM and from 7PM to 10PM in the surroundings of Ponichala situated in the eastern part of the city

The maximum values of the concentrations of the studied micro particles almost always exceed the values of the corresponding maximum allowable concentration.
The trend of hourly change of PM-particles concentrations in Rustavi differs from the results obtained in Tbilisi, since the content of micro particles in the atmosphere of the city of Rustavi is affected not only by the traffic intensity, but also by the mode of operation of industrial enterprises. As a result, their maximum content in the atmosphere of the city of Rustavi is observed in any interval of the day. Experimental measurements have shown that the tendency to increase the content of PM-particles in the atmosphere of the city of Rustavi determines both the flow of vehicles and emissions from industrial enterprises and meteorological conditions

Sacramento. The features of physical geography of selected areas are reviewed including inter annual distribution of precipitation and the unit runoff. The comparison between precipitation monthly averages in the Battle Creek sub-catchment and mean discharges of the river has revealed essential role of groundwater feeding in retaining the river runoff. The modeling of pasture irrigation in the basin of Cow Creek has demonstrated the increased watershedâs annual evaporative loss by 6%, resulting in 3 percent decline in the average flow volume downstream at the confluence and 0.6 meter drop in the mean groundwater elevation. The modeling of conditions required to maintain temperature regime necessary for the preservation of salmon population in the basin of Battle Creek has revealed the need of essential reconstruction of existing hydrotechnical infrastructure related with vast expenses. The modeling experience could be used in the future practice of integrated water management in the basins of separate rivers in Georgia.ÐÑеЎÑÑÐ°Ð²Ð»ÐµÐœÑ ÑезÑлÑÑаÑÑ Ð¿ÑÐžÐŒÐµÐœÐµÐœÐžÑ ÐŒÐŸÐŽÐµÐ»Ðž ОМÑегÑОÑПваММПгП ÑпÑÐ°Ð²Ð»ÐµÐœÐžÑ Ð²ÐŸÐŽÐœÑЌО ÑеÑÑÑÑаЌО WEAP 21 ÐŽÐ»Ñ ÑеÑÐµÐœÐžÑ ÐºÐŸÐœÐºÑеÑÐœÑÑ

It is shown, that the priority soil contaminant in eastern Georgia is copper, followed by lead, and silver concentrations are not significant. As for the content of heavy metals in the waters of water bodies, it is within the normal range and does not cause pollution
