Hydraulics of flow over side weirs
This thesis reviews the present state of knowledge of the hydraulics of flow over side weirs, and describes an experimental investigation into the flow of water over side weirs using a laboratory flume. A detailed exeimination is made of the assumption conventionally used by many investigators that the total energy of the flow remaining in the channel does not vary along the length of the side weir (excluding friction loss), and following consideration of oarlier warke in this subject. Some new conclusions are suggested concerning the weir coefficient, the variation of the velocity sind pressure distribution coefficients and the end controls. The secondary flow observed along the side weirs in the experimental work and the changes it underwent on progressing along the side weir are described in detail. Some degree of confirmation of the analysis was achieved for the exact way in which the flow moves along the side weir as it leaves the channel section and enters the side weir section.

Abstract
This thesis reviews the present state of knowledge of the hydraulics of flow over side weirs, and describes an experimental investigation into the flow of water over side weirs using a laboratory flume. A detailed exeimination is made of the assumption conventionally used by many investigators that the total energy of the flow remaining in the channel does not vary along the length of the side weir (excluding friction loss), and following consideration of oarlier warke in this subject. Some new conclusions are suggested concerning the weir coefficient, the variation of the velocity sind pressure distribution coefficients and the end controls. The secondary flow observed along the side weirs in the experimental work and the changes it underwent on progressing along the side weir are described in detail. Some degree of confirmation of the analysis was achieved for the exact way in which the flow moves along the side weir as it leaves the channel section and enters the side weir section. The background of the side weir theory is given in detail, preceding an examination of the predictions of this theory in terms of the results of the present and other experimental
