Workshop on "Karst Modeling

9814864赫斯：喀斯特水研究所计划于1999年2月24日至27日在弗吉尼亚州夏洛茨维尔举办喀斯特建模研讨会。该研讨会将汇集地下水水文学家和建模者、喀斯特研究人员、工程师和经济地质学家，讨论如何最好地量化喀斯特孔隙度以适应实际需要。水文学家的实地经验，建模者的计算机专业知识，以及喀斯特地貌和地球化学专家的研究往往是相互孤立的。为了使这一领域向前发展，有必要利用具有这些不同但互补背景的各种科学家的经验。“喀斯特建模”，正如本次研讨会所设想的那样，涉及概念、地球化学、数值、数学和统计模型的发展，这些模型可用于组织我们对喀斯特系统的知识。最重要的主题是：优化地下水供应；跟踪、监测和修复污染物；解决喀斯特地区土地稳定性问题。具体问题包括：(1)岩溶含水层中不同类型孔隙度（如粒间孔隙度、裂隙孔隙度和溶液孔隙度）的相对百分比是多少？它们的空间变异性是什么？(2)它们在水文上是如何相互作用的？(3)能否预测溶液管道的分布？(4)对周边含水层水头分布和流量有何影响？(5)如何预测或监测喀斯特含水层中的污染物路径？(6)是否有可能建立有效的岩溶含水层数字模型？如果是这样，传统的模型是否足够，或者是否有必要设计全新的软件？会议的结构将十分紧凑，以便这些议题能够相互建立，以确定理解上的差距，这些差距可以通过跨学科合作来最好地填补。研讨会的主题演讲者将是来自各个领域的知名专家，他们可以弥合这些差距。研讨会为期三天，包括对弗吉尼亚州喀斯特地区的实地考察。该研讨会的广告刊登在几个专业媒体上，包括Geotimes、GSA Today、EOS和地下水科学家和工程师协会的通讯。公告也将邮寄给主要的环境咨询公司、相关的州和联邦机构以及大学。扩展摘要将由喀斯特水研究所出版。会议摘要将提交给各适当的专业机构。

9814864Hess The Karst Waters Institute plans to sponsor a workshop on Karst Modeling, February 2427, 1999 in Charlottesville, Virginia. The workshop will bring together groundwater hydrologists and modelers, karst researchers, engineers, and economic geologists to discuss how best to quantify karst porosity to fit practical needs. The field experience of hydrologists, the computer expertise of modelers, and the geomorphic and geochemical studies of karst specialists are all too often isolated from one another. To allow the field to advance, it is necessary to draw on the experience of a broad variety of scientists having these diverse but complementary backgrounds."Karst modeling," as envisioned for this workshop, concerns the development of conceptual, geochemical, numerical, mathematical, and statistical models that can be used to organize our knowledge of karst systems. The most important topics are: optimizing groundwater supplies; tracking, monitoring, and remediating contaminants; and solving problems of land stability in karst. Specific questions include: (1) What are the relative percentages of the different types of porosity in a karst aquifer -- e.g., intergranular, fissure, and solution porosity -- and what is their spatial variability? (2) How do they interact hydrologically? (3) Can the distribution of solution conduits be predicted? (4) How do they affect the head distribution and flow within the surrounding aquifer? (5) How can one predict or monitor contaminant paths in karst aquifers? and (6) Is it possible to construct valid digital models of karst aquifers? If so, are traditional models adequate, or is it necessary to devise entirely new software?The meeting will be tightly structured so that these topics will build upon each other in order to identify gaps in understanding that can best be filled by interdisciplinary cooperation. Keynote speakers at the workshop will be well-known specialists from a variety of fields who can bridge these gaps. The workshop will be three days in length and include a field trip to karst areas in Virginia.The workshop is being advertised in several professional outlets including Geotimes, GSA Today, EOS, and the newsletter of the Association for Ground Water Scientists and Engineers. Announcements will also be mailed to major environmental consulting firms, relevant state and federal agencies, and universities. Extended abstracts will be published by the Karst Waters Institute. Meeting summaries will be submitted to various appropriate professional outlets.
