摘要

许多研究表明,塞瓦斯托波尔湾目前的水化学和水生物状况对该地区的生物多样性和娱乐潜力产生了负面影响。人口和旅游流量的增加,以及沿海地区资源的密集开发计划,实现了评估现有和规划的城市污水设施配置对游客最多的海滨地区和海水养殖发展的影响的任务。本文提出了一种计算城市污水对塞瓦斯托波尔湾水质影响函数的数值方法。对城市海滩、滨海大道、码头和贻贝养殖场进行了计算,并考虑了各种可能的排水口布置方案。我们比较了现有来源的数据,以了解城市污水排放口的布置和特点。对于影响函数场的每个图,我们分析了已知排放口与污染悬浮物不受欢迎的区域之间的连通性。分析表明,乌沙科娃Balka海滩最容易受到雨水和污水排放的影响。Severnaya一侧泊位附近的区域受到紧邻的排水口的强烈影响。城市中心雨水污水排放的悬浮物浓度对城市居民主要游憩场所的水质影响较大。

Search for an Optimal Configuration of Projected Municipal Sewerage Outfalls in the Sevastopol Bay using Computational Modelling and Geoinformation Analysis
Numerous studies have shown that the current hydrochemical and hydrobiological state of the Sevastopol Bay has a negative impact on its biodiversity and recreational potential of the region. An increase in population and tourist flow, as well as plans for intense development of the coastal zone resources actualize the task of assessing the impact of the existing and planned configuration of the municipal sewage facilities on the most visited seashore areas and mariculture development. We propose a numerical method for calculating the function of influence of municipal sewage on the quality of the Sevastopol Bay water. Calculations were performed for the city beaches, esplanade of Primorsky Boulevard, piers and the mussel farm with various potential options of outfalls arrangement in mind. We have compared the data from available sources as to arrangement and character of the municipal sewerage outfalls. We have analyzed the connectivity between the known outfalls and areas where contaminated suspended matter is undesirable for each map of the influence function field. The analysis showed Ushakova Balka Beach to be the most susceptible to storm water and sewerage discharge. The areas near the berths on the Severnaya Side are strongly influenced by the immediately adjacent outfalls. Concentration of suspended matter released from the stormwater sewerage in the city center has a dramatic impact on the water condition at major places of recreation of city residents.
