This action is to provide partial support for the First International Conference on Scour of Foundations (ICSF-1), to be held 17-20 November 2002 at Texas A&M University.The scouring of bridge foundations during flood conditions is an area of major concern to transportation officials. Poor correlation exists between calculated and observed scour depths, primarily because scour prediction equations developed under laboratory conditions do not adequately account for all the variables found in the field.Scour is a major problem in the United States. From 1961 to 1991, 1000 bridges collapsed and 600 of these collapses were due to scour, and lives were lost. The scour phenomenon is a water-soil interaction phenomenon which needs to be addressed through the cooperation of a number of disciplines, including hydraulic engineering, geotechnical engineering, hydrology, structural engineering, and construction. This conference will bring these disciplines together and enhance the participation of geotechnical engineers in solving this problem.The objectives of this conference are:1. To present and collect the latest international information on scour of foundations.2. To promote international discussion on research and practice of scour of foundations.3. To organize a prediction event to evaluate the precision of scour prediction methods.4. To promote the involvement of geotechnical engineers in the study of scour.The topics to be addressed include: scour of foundations, erosion of soils, scour at bridges, dams, offshore platforms, underwater pipelines, prediction of scour depth including pier scour, abutment scour, contraction scour, general degradation and aggradation, meander migration, countermeasures selection and design, monitoring, scour in gravel, sand, silt, clay and rock, laboratory measurements of erosion properties, field studies, case histories, failures and successes, international guidelines and practices, numerical modeling, model tests, field inspection, databases.

这一行动是为了向将于2002年11月17日至20日在得克萨斯州农工大学举行的第一届基础冲刷问题国际会议（ICSF-1）提供部分支持。 计算的冲刷深度和观测的冲刷深度之间的相关性较差，这主要是因为在实验室条件下开发的冲刷预测方程不能充分考虑现场发现的所有变量。 从1961年到1991年，1000座桥梁倒塌，其中600座是由于冲刷造成的，造成了生命损失。 冲刷现象是一种水土相互作用现象，需要水利工程、岩土工程、水文学、结构工程、建筑等多个学科的合作来解决。 这次会议将把这些学科聚集在一起，提高岩土工程师在解决这个问题的参与。介绍和收集国际上有关地基冲刷的最新信息.促进国际上对地基冲刷研究与实践的讨论.组织一次冲刷预报活动，对冲刷预报方法的精度进行评估.促进岩土工程师参与冲刷研究。研究课题包括：基础冲刷、土壤侵蚀、桥梁、大坝、海上平台、水下管道冲刷、冲刷深度预测（包括桥墩冲刷、桥台冲刷、收缩冲刷、一般退化和淤积）、曲流迁移、对策选择和设计、监测、砾石、沙子、淤泥中的冲刷，粘土和岩石、侵蚀特性的实验室测量、现场研究、案例历史、失败和成功、国际指南和实践、数值模拟、模型试验、现场检查、数据库。
