Streams in which sedimentation problems are encountered are extremely complex and developments within these streams depend on many factors, most of which are interrelated. Few basic principles are available to the design engineer in the solution of problems concerned with channel improvement and stabilization, and many of the plans and types of structures used have been based on experience and general judgment. Because of the difficulties and costs involved in experimenting with the actual river and the impracticality of comparing the effectiveness of various concepts and designs under the same conditions, the development of new principles and procedures or the optimum solution to many problems have to depend to a considerable extent on river model investigations coordinated with results in the field. This report is a general guide for laboratory engineers and technicians concerned with model invesitgations of sedimentation problems in alluvial streams. The report describes many of the principles and procedures used in the design, adjustment, and operation of movable-bed models and the factors to be considered in the development of improvement plans and in the interpretation of model results. Appendices cover the characteristics of model bed material, slopes required, and check list for model design and operation.
