Water balance prediction in stormwater infiltration basins using 2-D modeling:An application to evaluate the clogging process

Sustainable urban drainage systems are built along roads and in urban areas to collect urban runoff and avoid flooding, and to filter water pollutants. Sediment collected by runoff is deposited in the stormwater basin and progressively reduces water infiltration efficiency, leading to the clogging of the basin. To help stormwater basin managers and stakeholders better understand and predict clogging rates in order to elaborate maintenance plans and schedules, water transport prediction models are necessary. However,because of the heterogeneous sediment hydrodynamic properties inside the stormwater basin, a twodimensional(2-D) water flow model is required to predict water levels and possible overflow as accurately as possible. Saturated hydraulic conductivity(Ks) and sediment water retention curves were measured in the overall sediment layer of the stormwater basin, in addition to sediment layer thickness and organic matter content(11 sampling points). Sediment depth was used to predict organic matter(OM) content, and the OM was used to predict Ks. Water height in the basin was modeled with the HYDRUS-2 D model by taking into account the sediment hydrodynamic properties distribution. The HYDRUS-2 D model gave a satisfactory representation of the measured data. Scenarios of the hydraulic properties of stormwater basin sediment were tested over time, and hydraulic resistance, R, was calculated to assess the stormwater basin performance. Presently, after 20 years of functioning, the stormwater basin still ensures efficient water infiltration, but the first outflow(Hydraulic resistance,R > 24 h)) is expected to appear in the next 5 years, and clogging(R > 47 h) in the next 13 years. This 2-D water balance model makes it possible to integrate the hydrodynamic heterogeneity of a stormwater basin. It gives interesting perspectives to better predict 2-D/3-D contaminant transport.

The GSSP marking the base of the cambrian System was ratified by the IUGS in 1992. Ratification of the GSSP point at the base of the Trichophycus pedum Ichnozone in the Fortune Head section, eastern Newfoundland, canada, automatically defined the conterminant base of the lowermost series and stage of the cambrian although names for those subdivisions were not proposed at the time of the decision. In 2007, the IUGS ratified the names Terreneuvian Series and Fortunian Stage for these previously unnamed chronostratigraphic subdivisions. The Terreneuvian Series replaces the provisional name "Series 1," and the Fortunian Stage replaces the provisional name "Stage 1," of the cambrian System.

目前,旅游已经成为人们休闲娱乐的重要方式,除了去一些旅游景点外,近年来在中国,乡村旅游等特色旅游产业也有了快速的发展。尤其是中国一直以来,都将“三农问题”作为一个重要问题来对待,促进乡村发展与增加农民收入是中国政府的重要政策目标。在中国脱贫攻坚战略和乡村振兴战略下,乡村旅游产业有了较大的发展,各级政府在政策上也给予了大力支持。而在玻利维亚,乡村旅游的发展几乎是空白的,国家对旅游业发展的不重视、政局不稳定等因素都阻碍了旅游业的发展,乡村旅游更是得不到太多的政策支持。本文在对乡村旅游、乡村旅游政策等相关概念进行界定的基础上结合公共政策理论、可持续发展理论等相关理论,运用文献阅读法、内容分析法对中国乡村旅游核心政策和玻利维亚的国家层面的乡村旅游政策的政策主题、政策演化、政策内容结构进行分析,并在此基础上运用对比分析法研究中国和玻利维亚的乡村旅游政策特征的异同,结合玻利维亚的国情和乡村旅游的发展现状,总结分析中国乡村旅游政策对玻利维亚的借鉴作用,结构如下:第一部分为绪论,主要阐述了本文研究的研究背景、研究目标、研究意义、研究思路和研究方法等。第二部分为文献综述,通过对国内外有关乡村旅游政策的文献进行搜集和梳理,以求对乡村旅游的概念进行界定,并概述现有研究的状态,从而引出本文的研究内容。第三部分为理论分析,主要对乡村旅游、乡村旅游政策的概念进行界定,并阐述了公共政策理论、可持续发展理论以及对文献阅读法、内容分析法、对比分析法等方法进行了介绍。第四部分为中国的乡村旅游政策分析,以中国为主,分别从政策主题、政策演化、政策内容结构等三个维度进行了分析,并结合玻利维亚的乡村旅游政策内容的分析,在此基础上对两者的相同和不同之处进行了对比分析。第五部分在前文分析的基础上,结合玻利维亚的国情借鉴中国的乡村旅游政策,为玻利维亚乡村旅游政策的完善提出相应的建议。通过以上分析,不难看出,中国的乡村旅游政策对玻利维亚乡村旅游政策具有极强的借鉴意义。因此,本文在对中国乡村旅游政策进行深入分析的基础上,对中国乡村旅游政策进行借鉴,结合玻利维亚的具体国情,指出了玻利维亚目前乡村旅游政策方面存在的问题:(1)玻利维亚乡村旅游政策目标不够明确,缺乏系统的规划,各个主体对于乡村旅游的参与度不高,缺乏响应的旅游管理机制;(2)乡村旅游发展缺少统一的管理组织,乡村旅游法律制度不完善,难以做到对乡村旅游资源的统一管理,(3)资金缺口较大,对旅游管理专业人才的培养较为缺乏,对基础设施的政策支持力度不够。有针对性的对玻利维亚乡村旅游政策中存在的问题提出了相对应的建议:(1)做好乡村旅游统筹规划,引导多方参与合作开发,完善乡村旅游管理机制(2)加强乡村旅游组织构建,完善乡村旅游管理法律,加强乡村旅游的资源管理。(3)加大财政资金支持,加强人才培养与开发,加强基础设施建设。
