Hydraulics and Fluid Mechanics is a collection of papers from the Proceedings of the First Australian Conference held at the University of Western Australia on December 6-13, 1962 at Nedlands, Australia. This book deals with the science of hydraulics and fluid mechanics in their practical uses in industry and research. In special situations when high-pressure oil is used in mechanical equipment, hydraulic lock is preferred for valve control. This book reviews the pressure drop in the pneumatic transfer of granular solids in a pipe where a formula is derived to determine the pressure drop when using either a straight or bent pipe. This text also discusses the improvements on the cavitation performance of flow pumps by using prerotation at design points. The construction of a dam in Tasmania provides another study on the behavior of rock-fill slopes subjected to seepage. Here, the book analyzes the hydraulic forces acting on the rock particles, and explains theories on the derivation of the dynamic equation for spatially varied flow with increasing discharge on a steep slope. The book also examines the concept of critical depth in spatially varied flow with increasing discharge on a steep slope. This book investigates the use of a computer model designed to determine the methods of draining flooded farmlands either through hydraulically or electrically operated drainage systems. This text also evaluates the cost of constructing a project. This collection is suitable for people in the field of applied mathematics, physics, and engineering.

This book discusses coastal defense measures, which have not improved in the past few decades, and better alternatives. It emphasizes on the existence of stable bays in coastal geomorphology and their use in coastal stabilization. The conventional measures for saving beaches, such as seawalls, groins, offshore breakwaters, and renourishment, are discussed in detail, followed by an alternative known as headland control. Many types of coast, and the respective defense measures, are discussed, especially for eroding beaches downcoast of harbors with long breakwaters. The formation of offshore bars during storms is examined and the design of stable recreational beaches is demonstrated. Practical design problems are discussed in all cases. Many issues requiring attention in coastal engineering are also outlined.
