摘要推移质泥沙运动过程复杂，难以量化。现场测量提供了洞察力和改进预测方法的机会。描述了一个全面的数据库，其中包含来自近500个推移质泥沙输送数据集的15,000多个观测值。意见汇编自公布的资料来源、提交人对询问的答复以及对办公室的亲自访问。根据原始数据对每个条目的准确性进行了两次检查，并将其转换为一组通用单位。该数据库包含样品描述、排放和输送数据、河道和河滩特性、表层和次表层粒度分布以及可能情况下的河流分类描述符等部分。排污量从远低于岸值到数倍于岸值不等。该数据库向公众免费提供，可通过直接下载和通过基于WaterML的Web服务从杨百翰大学世界水数据沉积物迁移数据库访问。
AbstractThe processes involved in bed-load sediment transport are complex and difficult to quantify. Field measurements provide insight and a chance to improve predictive methods. A comprehensive database is described that contains more than 15,000 observations from nearly 500 data sets of bed-load sediment transport. Observations are compiled from published sources, author responses to queries, and personal visits to offices. Each entry has been checked twice for accuracy against the original data and converted to a common set of units. The database contains sections for sample descriptions, discharge and transport data, channel and bankfull characteristics, surface and subsurface grain size distributions, and, where possible, stream classification descriptors. Discharges range from far below to several times bankfull values. The database is freely available to the public and may be accessed via direct download and through WaterML based web services from the BYU World Water Data Sediment Transport Databa...
