Book Description
General studies were made to determine design parameters for hydraulic downpull and uplift forces on downstream seal, roller-mounted gates located in entrance transitions of large conduits. Effects of various gate lip extensions, and recesses in the gate shaft, were investigated for one seal extension. Uplift forces great enough to prevent closure of gates under their own weight were found. Uplift forces were controlled by proper shaping of offsets and recesses in the face of the gate shaft or bonnet. A gate lip extension to leaf thickness ratio of 0.55 was selected as the optimum compromise between structural and hydraulic considerations. Pressures on the gate bottoms, and hence the downpull, were significantly affected by the gate slots and side walls. Effects of air admission were also determined.

Book Description
Revised and updated, this second edition of Design of Hydraulic Gates maintains the same goal as the original: to be used as a textbook and a manual of design of gates, presenting the main aspects of design, manufacture, installation and operation of hydraulic gates, while introducing new products, technologies and calculation procedures. This edition included new chapters on intake gates and trashrack design, highlighting the aspects of safety, operational and maintenance procedures. To improve the strength against structural failure of intake trashracks, the author proposes a series of rigid calculation assumptions, design parameters and manufacturing procedures, which will certainly result in safer trashracks. Some 340 drawings and photographs, 82 tables, 107 references and 23 worked examples help the reader to understand the basic concepts and calculation methods presented.

Book Description
Measured hoist loads due to hydraulic downpull on powerhouse intake gates at Chief Joseph Dam were about twice as large as expected. For this reason model studies were necessary to determine the most practical gate bottom shape and the maximum hydraulic downpull to be considered when designing powerhouse intake gate hoists for Ice Harbor Project. Because prototype data were available, a typical intake, intake gate, penstock, and scroll case for Chief Joseph powerhouse were reproduced for a series of preliminary tests. The pattern and magnitude of downpull forces on the prototype intake gates were duplicated in the 1:25-scale model. Hydraulic forces on an intake gate in motion (closing) were compared with those for various openings of a stationary gate.
