摘要:

Several members of the IAHR section on the use of computers in hydraulics and water resources have expressed concern at the quality of many of the computational models currently used in hydraulic research and hydraulic and coastal engineering practice. The purpose of this article is to explain some of the grounds for their concern by illustrating some of the errors that commonly occur in this type of work. Since the article is intended only as a popular review, no attempt is made to provide a detailed treatment of problems, (which, indeed, already provides material enough for several extensive treatises, such as those of RoACHE, 1972, and MAKCHUK, 1974).

摘要:

The effects of small sinusoidal pressure fluctuations on a nappe springing clear of a broadcrested weir are analyzed, with particular reference to fluctuations in local and average velocity of the emerging nappe. Reference is made to the effects of pressure fluctuations measured during flutter experiments on a full-scale dam, and numerical values are given for this case.

摘要:

The extensive previous work on the hydraulic jump by the first two of the authors is taken as the basis for a fundamental discussion of the phenomenon. Special attention is focussed on considerations of conservation of mass and momentum. The resulting comprehensive integral relations are discussed in the light of experimental evidence.
