Book Description
Discharge coefficient is usually dependent on dimensionless parameters such as Reynold's number and Weber number associated with dynamic conditions of flow over the structure, and ratios of weir, notch and flume dimensions which reflect variations in the geometrical design of the measuring structures. The data are presented to provide engineers with a means of estimating discharge coefficients for rectangular weirs whether they are flat-topped or sharp-crested. The information contained herein will provide a description of the testing apparatus and the manner in which the discharge coefficients should be used. As part of the research conducted, discharge coefficient scale effects for weir, much data was collected for various flat-topped and sharp-crested weirs & the values for height/width are determined with the help of various methods. These are varied according to the dimension of the weirs & resulted into the small, intermittent and large ones. The material from which the structures are fabricated are obtained cheaply available in the market & the methods which are applied for cutting the structures in specific dimensions are done very easily, such as Gas-cutter method.

Book Description
In the context of water management, structures that measure the flow rate in open channels are used for a variety of purposes: (i) In hydrology, they measure the discharge from catchments; (ii) In irrigation, they measure and control the distribution of water at canal bifurcations and at off-take structures; (iii) In sanitary engineering, they measure the flow from urban areas and industries into the drainage system; (iv) In both irrigation and drainage, they can control the upstream water at a desired level. This thesis represents an attempt to place such flow measurements on a solid foundation by explaining the theory of water flow through 'long-throated flumes' and their hydraulically related 'broad-crested weirs'. On the basis of this theory, and on practical experience, these structures are recommended for use whenever the water surface in the channel at the measuring site can remain free. The thesis concludes with a design procedure that will facilitate the application of these structures. The idea to undertake research on discharge measurement structures was born upon my appointment as the first civil engineer with the International Institute for Land Reclamation and Improvement (ILRI). Because my recruiter, Ir. J.M. van Staveren, then Director of ILRI, had left the Institute before my arrival, and because I was the 'first of my kind' in an agricultural environment, I looked for contact and found - vii- support from: the late Prof. Ir. J. Nugteren, Prof. Ir.
