It has been established that the maximum concentrations of PM2.5 in the atmosphere of Rustavi are almost always higher than the corresponding maximum allowable concentrations. The trend of hourly changes in concentrations showed that during the day the concentration of microparticles reaches its maximum in the various period of the day. Numerical modeling of the local distribution of microparticles carried out in the city of Rustavi during background easterly light air, gentle and fresh breeze showed us that the change in the daily regime of relief and temperature with eastern light air in Rustavi for 12 hours leads to a complex and significant change in the wind speed directed to land. It forms on the territory of Kvemo Kartli the opposite current of the background wind, which corresponds to the horizontal circular wind circulation. The value of circulation gradually decreases with increasing height and in the boundary layer of the atmosphere (600 m above the earth's surface) has the form of a wave disturbance. the picture obtained with an average background east wind is qualitatively similar to the field obtained with a background light air, and with a fresh breeze, in contrast to the case of a light air and gentle breeze, the pollution zone covers most of the simulation zone.","PeriodicalId":301433,"journal":{"name":"Pressing Problems in Hydrometeorology and Ecology","volume":"25 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133136202","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to global climate change, especially since the 1990s, their number and intensity have increased. Calculation of the maximum discharges of freshets using Chezy formula is mainly given in the form of Table 1. In the article, as an example, the calculation of the discharge of the catastrophic freshet on the Vere River on 14 June 2015 for the adjacent section after the connection of the Napetvrebi ravine is given by 2 methods - using the Sokolovsky and Chezy formulas, and according to the maximum discharge calculated at the Napetvrebi ravine for the laboratory section and for the entire Vere river basin using the relative coefficients of their areas, the values of the maximum discharges of the June 14 catastrophic freshet were obtained in the amount of 477 and 512 m3/s, respectively. In addition, it should be noted that comparing all three results of the maximum discharges at Napetvrebi ravine, it can be seen that they are quite close to each other, which indicates the credibility of the maximum discharges of freshets calculated by us in the laboratory section from the 1990s to the present day using the Chezy formula.","PeriodicalId":301433,"journal":{"name":"Pressing Problems in Hydrometeorology and Ecology","volume":"140 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116444205","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are selected the stations of rivers which have the longest observed data series. These rivers are Alazani (H/S shakriani), river Mtkvari (H/S Khertvisi), river Paravani (H/S Khertvisi). As a result of actual observed data of minimum discharges were allocated to the research rivers, such as: · 30-day minimum discharge (non-calendar year) · Instantaneous minimum discharge · Minimum discharge taken from daily average data. Nowadays, in Georgia there is no legal basis and corresponding normative-technical documentation for determining the normative values of discharge of water discharged for ecological purposes which of course is the cause of numerous problems in terms of conservation and use of water resources. Therefore, it is crucially important to take into consideration the complex relationship between minimum and environmental flows.","PeriodicalId":301433,"journal":{"name":"Pressing Problems in Hydrometeorology and Ecology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129428809","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They occupy the largest area in Western Georgia in the western part of the Kolkheti Lowland and comprise 2200 km2, of which 29,000 ha are included within the Kolkheti National Park and Kobuleti protected areas. They were included in the list of the Ramsar Convention adopted in 1971, and in 2021 the Kolkheti Wetlands were added to the UNESCO World Heritage List along with the Kolkheti Rainforests. Wetlands’ role in preserving natural ecosystems and coastal protection is great. The active study of wetlands in Kolkheti dates back to the 20s of the last century when the research was carried out according to their distribution, types, origin, feeding regimes, and other parameters. The main goal of the studies was to utilize the swampy areas for agricultural purposes and, accordingly, to prevent the natural events characteristic of the rivers passing through these areas, mainly for Rion. Since the 90s of the 20th century, active research in Kolkheti swamps has decreased to almost zero, due to the severe socio-political situation in the country, and until now there are almost no scientific activities in terms of studying their modern condition and geographical components. Modern methods involve their research for protection and preservation, as well as the introduction of the principles of harmonious coexistence of man and nature. In addition, it is a necessary condition to develop wetland management plans taking into account social factors. Therefore, it is necessary to actively renew research in the Kolkheti region and accumulate new knowledge about wetlands, thus facilitating the implementation of sustainable development plans for the region.","PeriodicalId":301433,"journal":{"name":"Pressing Problems in Hydrometeorology and Ecology","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128565473","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
