Abstract

Surface runoff represents one of the major mechanism connecting sources, transport, deposition and storage of the particle matter in urban sediment cascade. The urban surface deposited sediment represents a medium for the transport and nonpoint source of pollution in cities. The study is aimed to characterize the role of surface stormwater runoff in accumulation of the contemporary surface deposited sediments in the urban environment taking to account the seasonal factor. The study was conducted on the example of residential area of Ekaterinburg, Russia. The role of the surface stormwater runoff in the formation of the urban surface deposited sediments was discussed. The snow and dirt mixture accumulates surface runoff and pollutants in it during the winter season in an urban area. A large supply of water accumulated in the snow cover during the cold period contributes to the formation of large volumes of snow-mud mixture during spring. The active snowmelt in the spring leads to the formation of snow-dirt sludge and transfer of the sedimentary material.

Abstract

Актуальность исследования обусловлена необходимостью изучения процессов осадкообразования на урбанизированной территории, которые снижают качество городской среды и оказывают негативное влияние на экологическую ситуацию. Цель: проанализировать метеорологические условия формирования поверхностного стока наносов в крупном городе в период интенсивного весеннего снеготаяния. Объект: урбанизированная территория города Екатеринбурга. Методы: изучение метеорологических условий за холодные периоды 2015-2016 и 2016-2017 гг., а также в весенние сезоны 2016 и 2017 гг.; оценка особенностей и различий метеорологических параметров и процессов, оказавших основное влияние на сток наносов весной 2016 и 2017 гг. Результаты. Ретроспективно восстановлены метеорологические условия холодных периодов 2015-2016 и 2016-2017 гг. и в весенние сезоны 2016 и 2017 гг. Были проанализированы метеорологические величины и процессы, оказавшие существенное влияние на поверхностный сток воды на урбанизированной территории: термический режим приземного воздуха, атмосферные осадки, снежный покров, снеготаяние, промерзание и оттаивание почвогрунтов. Установлено, что метеорологические условия весен 2016 и 2017 гг. существенно отличались друг от друга, что отразилось на формировании более интенсивного грязевого осадка в 2016 г. Весной в городской среде следующие погодные факторы являются определяющими при формировании поверхностного стока: запас воды, накопленный в снежном покрове за холодный период года; особенности термического режима в период снеготаяния (дружность весны, возвраты холодов); атмосферные осадки и интенсивность оттаивания грунта в период снеготаяния. Полученные результаты могут быть использованы при планировании мероприятий для улучшения экологической ситуации на урбанизированной территории. The relevance of the research is caused by the need to study sedimentation in urbanized area, which reduces the quality of urban environment and has negative effect on ecological situation. The main aim of the research is to analyze the meteorological conditions of surface sediment runoff formation in a large city during the intense spring snowmelt. Objects of the research is the urbanized area of the city of Yekaterinburg. Methods: study of meteorological conditions for the cold periods of 2015-2016 and 2016-2017, as well as in the spring seasons of 2016 and 2017; assess the features and differences of meteorological parameters and processes that had a major impact on the sediment runoff in the spring of 2016 and 2017. Results. The meteorological conditions of the cold periods 2015-2016 and 2016-2017 and the spring seasons 2016 and 2017 were reconstructed. Meteorological parameters and processes that had a significant impact on the sediment runoff in the urban area such as thermal regime of ground air, precipitation, snow cover, snowmelt, and freezing and thawing of soils were studied. The significant diference between meteorological conditions of the spring of 2016 and 2017 was found, that reflected in sedimentation and formation of more intense mud deposition in 2016. The following factors appear to be crucial for formation of surface sediment runoff in the urban environment in spring: water accumulated in the snow cover during the cold period of the year, characteristics of the thermal regime during snowmelt (duration, cold returns), precipitation and soil thawing intensity during the snowmelt. The results obtained can be used in planning the measures to improve the environmental situation in the urban areas.

Abstract

Abstract: The role of puddle sediments as a final depot of 137Cs horizontal migration within the urban landscape is studied using the example of Ekaterinburg city, Russia. Radioactive contamination in the city appeared due to fallout after atmospheric testing of nuclear weapons and nuclear accidents. Contamination density of 137Cs in the region was assessed from archive data to be about 5.1kBq/m2, of which the maximum activity concentration (<30Bq/kg) is associated with the upper 15cm soil layer. Results of the survey reported here indicate a mean 137Cs activity concentration in puddle sediments of 80Bq/kg, with a maximum value of 540Bq/kg. It is estimated that horizontal migration has led to about a fourfold concentration of 137Cs in puddle sediments. [Copyright &y& Elsevier]
