The natural resources of water that can be used for different purposes are referred to as water resources. It can be used in various household, industrial, agricultural and environmental activities. The management of different parts of the water cycle is known as water engineering. It aims to maximize the use of potable water as a precious and finite resource. Water engineering focuses on creating designs that are sustainable, safe and appropriate to the location, supportive to the local ecology, appropriate to the project's current future requirements and sensitive to anticipated shifts in climate. Water engineering also includes water treatment, hydraulic modeling and network modeling. The various sub-fields of water resources engineering along with technological progress that have future implications are glanced at in this book. It presents this complex subject in the most comprehensible and easy to understand language. Those in search of information to further their knowledge will be greatly assisted by this book.
