Abstract

The aim of this study is to provide a tool to assess sediment production in an urban area. The urban environment is affected by a variety of anthropogenic and natural factors that, in particular, lead to the sediment production. The storage of sediments in the urban landscape negatively affects the quality of the urban environment. The model was developed on the basis of landscape studies conducted in residential areas of six Russian cities. The model takes into account (1) the influence of precipitation, spring snowmelt, and vehicles, (2) the influence of erosion factors for two seasons: warm (t>5°C) and cold (t<5°C), and (3) the presence of disturbed surfaces. The application of the developed model to Ekaterinburg city conditions returned sediment production equal to 1.2 kg/m2/y. A comparison of seasonal values shows that sediment production in cold season is 2.5 times higher than in the warm season. In the absence of the disturbed surfaces, sediment production decreases to 0.44 kg/m2/y. Modeling showed a correlation between sediment production in Russian cities and duration of the cold season. The efficiency of various urban area maintenance practices and cleaning measures were evaluated in terms of sediment production and storage. The developed model presented in this paper is based on research in Russian cities, but can be applied to assess the formation of sediment and measures to reduce the value of its accumulation in the urban environment in different regions of the world.

模拟城市环境中的沉积物产生：俄罗斯城市案例

本研究旨在提供一种评估城市地区沉积物产生情况的工具。城市环境受到各种人为和自然因素的影响，这些因素尤其会导致沉积物的产生。沉积物在城市景观中的储存会对城市环境质量产生负面影响。该模型是在对俄罗斯六个城市的居住区进行景观研究的基础上开发的。该模型考虑了以下因素：(1) 降水、春季融雪和车辆的影响；(2) 温暖（t>5°C）和寒冷（t<5°C）两个季节的侵蚀因素的影响；(3) 受干扰表面的存在。将所开发的模型应用于叶卡捷琳堡市的条件下，得出的沉积物产生量为 1.2 千克/平方米/年。季节性数值比较显示，寒冷季节的泥沙产生量是温暖季节的 2.5 倍。在没有扰动表面的情况下，沉积物产生量减少到 0.44 千克/平方米/年。模型显示，俄罗斯城市的沉积物产生量与寒冷季节的持续时间有关。根据沉积物的产生和储存情况，对各种城市区域维护措施和清洁措施的效率进行了评估。本文中介绍的开发模型是基于俄罗斯城市的研究，但也可用于评估沉积物的形成，以及减少其在世界不同地区城市环境中积累值的措施。

期刊介绍： Journal “GEOGRAPHY, ENVIRONMENT, SUSTAINABILITY” is founded by the Faculty of Geography of Lomonosov Moscow State University, The Russian Geographical Society and by the Institute of Geography of RAS. It is the official journal of Russian Geographical Society, and a fully open access journal. Journal “GEOGRAPHY, ENVIRONMENT, SUSTAINABILITY” publishes original, innovative, interdisciplinary and timely research letter articles and concise reviews on studies of the Earth and its environment scientific field. This goal covers a broad spectrum of scientific research areas (physical-, social-, economic-, cultural geography, environmental sciences and sustainable development) and also considers contemporary and widely used research methods, such as geoinformatics, cartography, remote sensing (including from space), geophysics, geochemistry, etc. “GEOGRAPHY, ENVIRONMENT, SUSTAINABILITY” is the only original English-language journal in the field of geography and environmental sciences published in Russia. It is supposed to be an outlet from the Russian-speaking countries to Europe and an inlet from Europe to the Russian-speaking countries regarding environmental and Earth sciences, geography and sustainability. The main sections of the journal are the theory of geography and ecology, the theory of sustainable development, use of natural resources, natural resources assessment, global and regional changes of environment and climate, social-economical geography, ecological regional planning, sustainable regional development, applied aspects of geography and ecology, geoinformatics and ecological cartography, ecological problems of oil and gas sector, nature conservations, health and environment, and education for sustainable development. Articles are freely available to both subscribers and the wider public with permitted reuse.
